Science SOL 5.2 Energy Assessment

Front

What form of energy does a moving object possess?

Back

Mechanical energy is the energy that an object has due to its motion or position.

Front

When is work done?

Back

Work is done only when a force moves an object.

Front

What energy transformations occur in a lamp that plugs into a wall socket?

Back

The energy transformations are electrical → thermal → light.

Front

What device transforms electrical energy into mechanical energy and sound?

Back

A pencil sharpener plugged into a wall outlet.

Front

What is energy?

Back

Energy is the ability to cause change.

Front

What type of energy is associated with the position of an object?

Back

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

Front

What is kinetic energy?

Back

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

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of electrical energy?

Back

Electrical energy is the energy carried by electric current, such as the energy used to power a light bulb.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.
