Forces and Motion Review

Front

What is speed?

Back

Speed is the distance traveled per unit of time, calculated as distance/time.

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the Earth.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What happens to an object in motion if no forces act on it?

Back

An object in motion will continue to move at a constant speed in a straight line.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
