Chapter 3: Dynamics
Newton's laws of motion
Linear momentum and its conservation
(a) State and apply each of Newton's laws of motion.
(b) Show an understanding that mass is the property of a body which resists change in motion (inertia).
(c) Describe and use the concept of weight as the force experienced by a mass in a gravitational field.
(d) Define and use linear momentum as the product of mass and velocity.
(e) Define and use impulse as the product of force and time of impact.
(f) Relate resultant force to the rate of change of momentum.
(g) Recall and solve problems using the relationship F = ma, appreciating that resultant force and acceleration are always in the same direction.
(h) State the principle of conservation momentum.
(i) Apply the principle of conservation of momentum to solve simple problems including inelastic and (perfectly) elastic interactions between two bodies in one dimension (knowledge of the concept of coefficient of restitution is not required).
(j) Show an understanding that, for a (perfectly) elastic collision between two bodies, the relative speed of is equal to the relative speed of separation.
(k) Show an understanding that, whilst the momentum of a closed system is always conserved in interactions between bodies, some change in kinetic energy usually takes place.
