Energy

What is potential energy?

• Energy possessed by an object due to its motion.

• Energy possessed by an object due to its temperature.

• Energy possessed by an object due to its position or condition.

• Energy possessed by an object due to its color.

Give an example of an object with high potential energy.

• A car parked on a hill.

• A roller coaster at the top of a hill

• A book on a shelf.

• A basketball at the top of a hoop.

What is kinetic energy?

• Energy possessed by an object due to its motion.

• Energy possessed by an object due to its shape.

• Energy possessed by an object due to its temperature.

• Energy possessed by an object due to its position.

What is the formula to calculate kinetic energy?

• KE = mass * velocity^2

• KE = mass * velocity

• KE = 1/2 * mass * velocity

• KE = 1/2 * mass * velocity^2

Which type of energy does a moving car have?

• kinetic energy

• nuclear energy

• thermal energy

• potential energy

What happens to potential energy when an object is lifted higher?

• The potential energy decreases.

• The potential energy increases.

• The potential energy remains the same.

• The potential energy becomes zero.

What happens to kinetic energy when the speed of an object increases?

• Kinetic energy becomes negative.

• Kinetic energy remains constant.

• Kinetic energy decreases.

• Kinetic energy increases

What is the unit of measurement for energy?

• Joule (J)

• Watt (W)

• Volt (V)

• Ampere (A)

What is the law of conservation of energy?

• Energy can be created but not destroyed.

• Energy can be both created and destroyed.

• Energy cannot be created or destroyed, only transferred or transformed.

• Energy can be destroyed but not created.

Explain the difference between potential and kinetic energy.

• Potential energy is the energy possessed by an object due to its motion, while kinetic energy is the energy possessed by an object due to its position or condition.

• Potential energy is the energy possessed by an object due to its shape or size, while kinetic energy is the energy possessed by an object due to its color or texture.

• Potential energy is the energy possessed by an object due to its temperature, while kinetic energy is the energy possessed by an object due to its weight or mass.

• Potential energy is the energy possessed by an object due to its position or condition, while kinetic energy is the energy possessed by an object due to its motion.
