Physics Laws of Motion Quiz

A ________ is a push or pull on an object.

________ forces can create changes in motion. These occur when net force is greater than zero.

________ forces do not create changes in motion. These occur when net force is equal to zero.

Newton's second law tells us that when force on an object increases, acceleration ________. When the mass of an object increases, acceleration ________.

Inertia is the tendency of an object to resist changes in motion.

Motion is a change in position over time.

Speed is a measure of how far something moved (distance) divided by the given amount of time it took to travel that distance.

Velocity is speed in a specific direction.

Acceleration is the change in velocity over time. This means an object changes speed, direction, or both.

You're playing catch with a friend using balls of different masses. First, you toss a small tennis ball to your friend, then you toss a heavy bowling ball. You exert the same amount of force for each throw. Which ball will experience more acceleration, and why?
