6th Grade Semester 1 Exam Review

Front

What type of wave can travel through a vacuum or empty space?

Back

Transverse or electromagnetic waves can travel through a vacuum.

Front

What happens to potential energy when a spring is compressed?

Back

Compressing a spring increases its potential energy.

Front

What is the sequence of energy conversion from solar energy to usable energy for humans?

Back

Radiant energy → chemical energy → mechanical energy.

Front

Which object has the most potential energy?

Back

A boulder at the edge of a cliff has the most potential energy.

Front

At which point does a falling rock have the most kinetic energy?

Back

The rock has the most kinetic energy at point 3.

Front

Define kinetic energy.

Back

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

Front

Define potential energy.

Back

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

Front

What is the difference between mechanical energy and chemical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, while chemical energy is the energy stored in the bonds of chemical compounds.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is light.

Front

What is an example of a longitudinal wave?

Back

An example of a longitudinal wave is sound.
