Energy Test

Front

What is the energy conversion that occurs when gasoline is used in a car?

Back

Chemical energy is converted to mechanical energy.

Front

What energy transformations occur when a student rubs their hands together rapidly?

Back

Chemical energy is transformed into mechanical energy, which is then transformed into thermal energy.

Front

What type of energy is associated with a moving skateboard?

Back

Kinetic energy.

Front

What is the formula for gravitational potential energy (GPE)?

Back

GPE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

Electrical energy is transferred to which type of energy?

Back

Thermal energy.

Front

Define kinetic energy.

Back

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

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy increases with an increase in mass.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with an increase in height.

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 mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.
