Physical Science Review

Front

What happens to an object when the temperature decreases?

Back

The object contracts.

Front

What is the process called when heat is transferred through ocean and wind currents?

Back

Convection.

Front

In which direction does heat always flow?

Back

From the hot object to the cold object.

Front

What effect does more friction have on the speed of an object?

Back

It decreases the speed of the object.

Front

If an object travels 3 meters in one second, 6 meters in two seconds, and 9 meters in three seconds, what can we say about its speed?

Back

It is moving at a constant rate.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves.

Front

What is the definition of temperature?

Back

A measure of the average kinetic energy of the particles in a substance.

Front

What is the relationship between mass and speed when friction is present?

Back

More mass can lead to more friction, which can decrease speed.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.
