Force and Motion Test Study Guide

Front

Why would the crash affect the motion of the satellite, and which crash caused a greater change in motion for the satellite?

Back

The crash affects the motion due to the change in velocity, and the crash with the greater force caused a greater change in motion.

Which toy boat(s) experienced the strongest force when it was bumped? How do you know? Options: The blue toy boat experienced the strongest force because it takes a stronger force to slow something down than it takes to speed something up., The gray toy boat experienced the strongest force because it had the fastest ending speed., The orange and gray toy boats experienced the strongest forces because they both gained the same force as they sped up. The blue boat lost force, so it slowed down., All three toy boats experienced the same strength force because they changed speed by the same amount.

Back

All three toy boats experienced the same strength force because they changed speed by the same amount.
