## Investigation: Momentum and Collisions

You will be investigating momentum and collisions using

Compare TOTAL kinetic energy

$$KE_{total}=\frac{1}{2}m_1v_1^2+\frac{1}{2}m_2v_2^2$$

and TOTAL Momentum

$$\vec p_{total}=m_1\vec v_1+m_2\vec v_2$$

 level 1 level 2 level 3 level 4 Can you draw important conclusions about in elastic and inelastic collisions momentum and energy You can differentiate elastic and inelastic collisions based on conservation laws. You have done some independent research to verify your conclusions. You can differentiate elastic and inelastic collisions based on conservation laws. You have done some independent research and verified your conclusions, noting any differences between a theoretical and measured result.
