Forms of Energy

What is kinetic energy?

• The energy of motion

• The energy of rest

• The energy of light

• The energy of sound

What is the formula to calculate kinetic energy?

• mass * velocity^2

• 1/2 * mass * velocity

• mass + velocity^2

• 1/2 * mass * velocity^2

Give an example of an object with high kinetic energy.

• A parked bicycle

• A speeding car

• A stationary rock

• A sleeping cat

How does the mass of an object affect its kinetic energy?

• The mass of an object has no effect on its kinetic energy

• The mass of an object increases its potential energy

• The mass of an object decreases its kinetic energy

• The mass of an object affects its kinetic energy by directly influencing it.

How does the speed of an object affect its kinetic energy?

• The kinetic energy increases as the speed of the object increases.

• The kinetic energy remains constant regardless of the speed of the object.

• The kinetic energy decreases as the speed of the object increases.

• The speed of the object has no effect on its kinetic energy.

Explain the concept of potential energy.

• Potential energy is the energy that an object has due to its color.

• Potential energy is the energy that an object has due to its speed.

• Potential energy is the energy that an object has due to its position or state.

• Potential energy is the energy that an object has due to its temperature.

Differentiate between kinetic and potential energy.

• Kinetic energy is the energy of heat, while potential energy is the energy of electricity.

• Kinetic energy is the energy of sound, while potential energy is the energy of light.

• Kinetic energy is the energy of motion, while potential energy is the stored energy of an object.

• Kinetic energy is the energy of rest, while potential energy is the energy of movement.

What are the different forms of kinetic energy?

• Wind energy, geothermal energy, tidal energy, nuclear energy

• Mechanical energy, thermal energy, radiant energy, and electrical energy

• Potential energy, sound energy, chemical energy, nuclear energy

• Light energy, magnetic energy, gravitational energy, elastic energy

Explain the concept of mechanical energy.

• Mechanical energy is the energy stored in chemical bonds.

• Mechanical energy is the energy produced by machines only.

• Mechanical energy is the sum of potential energy and kinetic energy in an object.

• Mechanical energy is the energy generated by wind and water.

Give an example of an object with both kinetic and potential energy.

• A stationary rock

• A moving car

• A book on a shelf

• A light bulb
