Unit 05: Force, Motion & Energy Practice

Front

What is the force that opposes the motion of a sliding object?

Back

Friction is the force that opposes the motion of a sliding object.

Front

What is an example of kinetic energy?

Back

A flying airplane is an example of kinetic energy.

Front

Which object has kinetic energy?

Back

A rolling ball has kinetic energy.

Front

What type of force is friction?

Back

Friction is a force that opposes motion.

Front

What does the term 'speed' refer to in physics?

Back

Speed refers to how fast an object is moving.

Front

What is the definition of motion?

Back

Motion is the change in position of an object over time.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move or change its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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 an example of potential energy?

Back

A book on a shelf has potential energy due to its height.
