Unit 05: Force, Motion & Energy Practice

Front

What is kinetic energy?

Back

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

Front

Give an example of kinetic energy.

Back

A flying airplane is an example of kinetic energy.

Front

What type of force is friction?

Back

Friction is a force that opposes motion.

Front

What does it mean when we say a bicycle is traveling south at 15 km/h?

Back

It describes the bicycle's direction and speed.

Front

What effect does friction have on a moving object?

Back

Friction opposes the object's motion.

Front

What is potential energy?

Back

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

Front

How does gravity affect motion?

Back

Gravity pulls objects toward the Earth, affecting their motion.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces cause an object to change its motion.
