Physics Topic: Dynamics

  1. State each of Newton’s laws of motion.

  2. Show an understanding that mass is the property of a body which resists change in motion.

  3. Describe and use the concept of weight as the effect of a gravitational field on a mass.

  4. Define linear momentum and impulse.

  5. Define force as rate of change of momentum.

  6. Recall and solve problems using the relationship F = ma, appreciating that force and acceleration are always in the same direction.

  7. State the principle of conservation of momentum.

  8. Apply the principle of conservation of momentum to solve simple problems including elastic and inelastic interactions between two bodies in one dimension. (Knowledge of the concept of coefficient of restitution is not required.)

  9. Recognise that, for a perfectly elastic collision between two bodies, the relative speed of approach is equal to the relative speed of separation.

  10. Show an understanding that, whilst momentum of a system is always conserved in interactions between bodies, some change in kinetic energy usually takes place.
