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
