Energy Review for Test

What types of energy does a stretched rubber band have?

• Kinetic energy

• Potential energy

• Thermal energy

• Chemical energy

• Elastic Energy

Answer explanation

A stretched rubber band possesses potential energy due to its position or configuration, which can be released when the band is allowed to return to its original state.

In a roller coaster ride, where does kinetic energy reach its maximum?

• At the top of the hill

• At the bottom of the hill

• At the start of the ride

• At the end of the ride

• None of the above

Answer explanation

Kinetic energy reaches its maximum at the bottom of the hill due to the highest speed achieved at that point.

Food is considered to be which types of energy?

• Kinetic energy

• Potential energy

• Thermal energy

• Mechanical energy

• Chemical energy

Answer explanation

Food stores chemical energy, which is released during digestion and metabolic processes to provide energy for the body.

When a car brakes to stop, what energy transformation occurs?

• Kinetic to Potential

• Potential to Kinetic

• Kinetic to Thermal & Sound

• Chemical to Electrical

• Mechanical to electrical

Answer explanation

When a car brakes to stop, the kinetic energy of the moving car is converted into thermal energy due to friction between the brake pads and the wheels.

What types of energy does a battery store?

• Kinetic energy

• Potential energy

• Thermal energy

• Chemical energy

• Electrical energy

Answer explanation

A battery stores potential energy due to the separation of charges, chemical energy from the chemical reactions happening inside, and electrical energy when it is connected in a circuit.

In a stretched spring, what type of energy is being stored?

• Kinetic energy

• Elastic Potential energy

• Thermal energy

• Electrical energy

• Sound energy

Answer explanation

In a stretched spring, elastic potential energy is being stored as the spring is deformed from its equilibrium position.

When you use in a lamp, what energy transformation occurs?

• Kinetic to potential
• Potential to kinetic
• Electrical to thermal & radiant

• Mechanical to electrical
• Thermal to electrical

Identify the type of energy transformation that occurs in a microwave oven.

• Electrical to Radiant (invisible) to Thermal

• Electrical to Thermal

• Mechanical to electrical
• Chemical to electrical
• Electrical to mechanical
