What is the range of possible values for the coefficient of restitution ee?

0≤e≤10 \le e \le 1

What value of ee indicates a perfectly elastic collision?

e=1e = 1

What happens when the coefficient of restitution e=0e = 0?

Objects stick together (no rebound)

Newton's experimental law states that ee equals what ratio?

Speed of separation to approach

If u1=20u_1 = 20 m s−1^{-1} and u2=−4u_2 = -4 m s−1^{-1}, what is the speed of approach?

24 m s−1^{-1}

For oblique impact with a smooth plane, what happens to the parallel velocity component?

It remains unchanged

For oblique impact perpendicular to a plane, which equation applies?

e=vyuye = \frac{v_y}{u_y}

Which two equations are needed to solve direct collision problems?

Momentum and Newton's law

When an object collides with a wall, is momentum conserved for that object?

No, wall exerts external force
