Physical Science Fall Final Review

Front

What is the true statement about heat transfer?

Back

Energy as heat is transferred from a higher temperature to a lower temperature.

Front

What is defined as the transfer of energy by a force acting on an object as it is moved?

Back

Work.

Front

In what states of matter does convection occur?

Back

Convection occurs in liquids and gases.

Front

What consists of an object's speed and direction?

Back

Velocity.

Front

How do you calculate average speed?

Back

Average speed = total distance / total time.

Front

What is the average speed of a runner who runs 500.0 meters in 96 seconds?

Back

5.2 m/s.

Front

What is the definition of energy?

Back

The capacity to do work or produce heat.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.
