Kinetic Energy
What affects the magnitude of the damage in a collision: the speed at which a vehicle is travelling or the mass of the vehicle?
Concept: Newton’s 2nd Law of Motion
Essential Question: How does an object’s mass affect its change in motion (aka acceleration) during a collision?
Speed plays a greater role in the amount of damage produced by a collision than mass.

Mass, Speed, and KE Lab
Distance vs. Mass
Lab Video - Distance vs mass.movDistance vs. Mass
First, read and complete the background and the lab before you do anything. Answer the questions on the pages. Then use the video clip to get an idea of how the receiver car moves when the mass of the source car is changed. Note: the data to the bottom right is NOT from the video. The video is just a demonstration of the lab with different mass added to the source car. Use the data below for your data table, and then graph it. Answer the follow up questions.
