Physics Laws of Motion Quiz

A (a)   is a push or pull on an object.

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

(a)   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.

(a)  

Motion is a change in position over time.

(a)  

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

(a)  

Velocity is speed in a specific direction.

(a)  

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

(a)  

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?
