Online classes are going on and I was so fussed with my science I was so good at it but now m y physics got poorer then I searched for chapter force and law of motion ,got your videos and now tomorrow is my online periodic test and I am prepared for the chapter.
Just think of Force as an thing that makes things move in a certain direction. We can then use numbers to measure the speed of the movement, how long it will move, how strong it moved, etc. Force is the thing that makes things move.
Forces can stop an object, start an object to move, change the direction of an object, change the shape of an object, and also increase/decrease the speed of an object.
Wait did I really just forget forces and motion? Nah da da da da da da da alright na na na na, when I popped off and the science notebook went out of the world. It went like lalalalala! I got my brain shining like shashashasha I got your teacher like lalalala. Damn I made a song on the spot
This is such a great video! I never really understood the concept of Forces, but now I understand it's a disturbance in the velocity of an object. That is so cool!
Thank you so much for your appreciation. We are really happy to hear that it was helpful to you. We are glad that you understood the concept. For more videos, please visit our website - dontmemorise.com/
Same I am doing a presentation about energy and I am learning from videos and this one has already helped I have gotten 2 slides just from this video thank you

For a rolling ball, it is less about friction and more about a likely deformation of the ball that causes the ball to lose energy (energy is transferred to its own motion of particles) and come to a stop. Thoughts?
ma'am I loved your video on all maths stuff ,I would like that you do a video on Limits ,Derivatives and Integration.Please do it ma'am as there are asked in cpt of CA, Jee and other exams .
Force does not exist physically like an object with mass. Force, as we know it, turns out to be nothing more than an expression to express an idea like one would use the word "Love" to express once feelings. Force or Net Force is not the initial cause of motion. Energy (applied energy) is the origin of motion and not Force. Example: Choose an object of your choices and without applying the energy from within you, try to push and pull by applying "only" the Force or Net Force. Meaning that Energy (applied energy) is the origin of motion and not "Force". Once Energy (E) is applied, it creates what is known as Momentum (p). When this Momentum (p), which is mass and velocity, comes in contact with an object(s), it makes a surface contact that will enable you to push and pull. Energy (E) and Momentum (p) or "Ep", are not to be confused with Kinetic Energy in any way. Without Energy, there is no Momentum. Without Momentum, there is no surface contact on an object(s) to push, pull, work, shaping objects, motion, gravity, magnetism, radiation, etc. Momentum does not and cannot exist without the applied Energy that creates it. Energy and Momentum or "Ep", is the only common denominator that links all fundamental forces of nature. Without Ep, all fundamental forces of nature would be inert or non-existence. ~Guadalupe Guerra
@BRANSON TORO Sadly, RU-vid doesn't show dislikes, but just so u know, i totally disliked u. Thumbs-down. Through LOADS of devices. And i basically dislike YOU. what u are saying is a very lame thing to say in the comment section of educational videos. I mean, this comment section is filled with people who actually TRY instead of wallow in their miserably pitiful lives full of theories such as "always failing". So find another person to discourage; no place for you here. :(
Force (physics) does not exist physically in the same way that an object with mass, thus making it “not” the initial cause of pushing, pulling, shaping objects, motion, work or being a Vector Quantity (Magnitude + Direction). In physics, the word, “Force” as we know it, turns out to be nothing more than an expression to express an idea, like one would use the word “Love” to express one's feelings. But, physics and in mathematics, still use “Force” as thou it were something physical that could enable the initial cause of motion making it counterintuitive. Example: Without applying the Energy from within you, choose an object of your choices to push and pull by simply applying “only” the Force or Net Force. Meaning that Energy (applied energy) is the origin of motion and not “Force”. Once Energy (E) is applied, it creates what is known as Momentum (p). When this Momentum (object in motion) comes in contact with another object(s), it makes a surface contact that will enable you to push and pull. Example: Ep=ma, Ep=mv and so on. Note: Ep is not to be confused as Kinetic Energy in any way. Momentum represents things like work, wave, gravity, light, lightning, tsunami, earthquake, current, electricity, motion, magnetism, hurricane, etc. Without Energy, there is no Momentum. Without Momentum, there is no surface contact on an object(s) to push, pull, work, shaping objects, motion, etc. Momentum does not and cannot exist without the applied Energy that creates it. Energy and Momentum or “Ep” is the one and only common denominator that links all fundamental forces of nature. Without Ep, all fundamental forces of nature would be inert and non-existence. Energy is energy, but it’s when Energy (E) is being applied that creates the Momentum (p) making it the initial cause of motion. Example: Ep. By applying the right amount of Energy, nothing is immovable or unstoppable. ~ Guadalupe Guerra
Mam , what happens if the net force applied on the ball is not 0 ? What if we decrease the air resistance but dont make it negligible? Will the more gravitational force create fiction? And the ball will come to a hold?
Physics (F=ma) test: “Without” applying the Energy from within you, choose an object of your choice, and apply only the Force or Net Force needed to push it away from you or pull it towards you. Please let me know if you’re able to. This is only a test. Thank you.
Excellent video, there was a misconception though (4:45). Both the kick force and the force exerted by the ball on the kicker's foot are equal. The ball simply moves because it has a lower mass than the kicker, which gets the force distributed across his leg and hips.
Hi.. Pls subscribe and support my RU-vid channel.. I'm new to you tube.. Trying to solve physics question paper which will be helpful to understand the basics
Unfortunately the author does the same mistake as most text books: she puts a gravitational force equal to a electromagnetic (EM) force. Newtons third law says that the two force must be of the same KIND. There are in total 4 forces and we have to pair them correctly. The two EM forces at the contact point are equal. The gravitational force from the ball and the earth are also equal. The Physics books are full of such mistakes (hundreds) which we just repeat as we have learnt. Often that is not a problem however
Earth is NOT flat (Unless you r a flat earth believer) Earth is mostly round and it has a centre so when it says that gravitational force pulls the ball to the centre of the earth, then the ball remaining still(or stationary) is right! Since the core is in the middle of the earth and gravitational force is applied to every object
4:51 is wrong by the way, according to Newton's Third Law of Motion if object A applies a force on object B then object B will exert same magnitude of force but in opposite directions. So in this example the force the ball applies to your foot is the same as the force you kicked the ball with. The reason why the ball moves is because the ball has SO LESS INERTIA than the leg you kicked the ball with. NOT BECAUSE IT APPLIES SMALLER FORCE THAN THE KICK .
who else has parents that make then do work when ur not even doing a test on and when u have just started a new topic u dont understand they make u do hours of work at the weekend HELP ME

Yes bro you are right ball can't roll without friction it can only slide because to roll the ball torque if friction is important But here is the basic defination 😂
This video is very informative, my knowledge has been more expanded because of this video, now I've learned that there is not only one but multiple types of forces.
Don't forget to watch the second part of this video, here's the link - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iGwBZTWySWk.html To watch more physics videos, click here - bit.ly/Physics_DMYT To learn more about Forces, enroll in our full course now - infinitylearn.com/cbse-fullcourse?RU-vidDME&B6mi1-YoRT4&Comment
there is an error, you say (1:45) "for the object to move, there has to be some net force". that is wrong, because an object could be moving, and yet without any net force applied, that happens in uniform linear motion, where the object moves with constant velocity. your phrase could be changed to "for an object to accelerate, there has to be some net force applied, if not, the object maintains a constant velocity, or remains stationary (zero velocity)". many thanks for your great videos.
You're most welcome Huong. We are really happy to hear that it was helpful to you. We are glad that you understood the concept. Do support us by subscribing to our channel. 👍👍
Very nice video but you messed up majorly at the end. If you kick the ball the force of the ball on you isnt smaller, it is the same. The reason why the ball moves forward but you dont move backwards is because the friction withe the floor stopping you from going backwards (friction is differenr for you and the ball).
"Force does not exist physically in the same way that an object with mass does. This means that force cannot make surface contact with an object, much less push or pull it. The initial cause of all bodies in motion originates from the applied energy (E), which creates the momentum (p) necessary to make surface contact with an object, thereby enabling it to push and pull. This concept is mathematically expressed as Ep or the equation Ep = ma. Force was originally used as a placeholder by Sir Isaac Newton because he did not know the true nature of this force." ~ Professor Guadalupe Guerra from Laredo, Texas c/s
