2 Kinematics
2.1 Equations of motion
Candidates should be able to:
1 define and use distance, displacement, speed, velocity and acceleration
2 use graphical methods to represent distance, displacement, speed, velocity and acceleration
3 determine displacement from the area under a velocity-time graph
4 determine velocity using the gradient of a displacement-time graph
5 determine acceleration using the gradient of a velocity-time graph
6 derive, from the definitions of velocity and acceleration, equations that represent uniformly accelerated motion in a straight line
7 solve problems using equations that represent uniformly accelerated motion in a straight line, including the motion of bodies falling in a uniform gravitational field without air resistance
8 describe an experiment to determine the acceleration of free fall using a falling object
9 describe and explain motion due to a uniform velocity in one direction and a uniform acceleration in a perpendicular direction
3 Dynamics
An understanding of forces from Cambridge IGCSE/O Level Physics or equivalent is assumed.
3.1 Momentum and Newton’s laws of motion
Candidates should be able to:
1 understand that mass is the property of an object that resists change in motion
2 recall F = ma and solve problems using it, understanding that acceleration and resultant force are always in the same direction
3 define and use linear momentum as the product of mass and velocity
4 define and use force as rate of change of momentum
5 state and apply each of Newton’s laws of motion
6 describe and use the concept of weight as the effect of a gravitational field on a mass and recall that the weight of an object is equal to the product of its mass and the acceleration of free fall
3.2 Non-uniform motion
Candidates should be able to:
1 show a qualitative understanding of frictional forces and viscous/drag forces including air resistance (no treatment of the coefficients of friction and viscosity is required, and a simple model of drag force increasing as speed increases is sufficient)
2 describe and explain qualitatively the motion of objects in a uniform gravitational field with air resistance
3 understand that objects moving against a resistive force may reach a terminal (constant) velocity

3.3 Linear momentum and its conservation
Candidates should be able to:
1 state the principle of conservation of momentum
2 apply the principle of conservation of momentum to solve simple problems, including elastic and inelastic interactions between objects in both one and two dimensions (knowledge of the concept of coefficient of restitution is not required)
3 recall that, for a perfectly elastic collision, the relative speed of approach is equal to the relative speed of separation
4 understand that, while momentum of a system is always conserved in interactions between objects, some change in kinetic energy may take place
