2) A moving object's kinetic energy is a function of its mass and its velocity. EK = (m*v2)/2
3) A moving object's momentum is also a function of its mass and its mass and its velocity. P = m*v
4) Kinetic energy and momentum are different quantities, but both can answer the question "How much will it hurt when it hits me?"
5) What are the respective terminal velocities of a falling penny, bullet, and bowling ball?
6) What are the respective masses of a penny, bullet, and bowling ball?
7) What are the respective kinetic energy and momentum of a penny, bullet, and bowling ball?
8) Rate the three object is order of how much they will hurt you when they hit you.

One very slight correction: An object falling in the atmosphere does not necessarily maintain its terminal velocity to impact with the ground unless the air is still. [Objects with very low terminal velocities display this characteristic all the time.]
