Front

What is a collision?

Back

A collision is the moment when two objects hit each other.

Front

What direction must a force come from to stop an object in motion?

Back

The force must come from the opposite direction as the object's motion.

What is force?

Back

Force is a push or pull on an object that can cause it to change its velocity.

Front

What is speed?

Back

Speed is the distance an object travels per unit of time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is inertia?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.
