What is kinetic energy?

• The energy of an object at rest.

• The energy of an object in motion, calculated using the formula KE = 1/2 mv².

• The energy stored in an object due to its position.

• The energy released during a chemical reaction.

What is the law of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be created, not destroyed.

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy is a constant that does not change.

What is energy?

• Energy is the ability to do work or cause change.

• Energy is a measure of temperature.

• Energy is the total amount of matter in an object.

• Energy is the force exerted by an object in motion.

What is gravitational potential energy?

• The energy an object possesses due to its height above the ground, calculated using the formula GPE = mgh.

• The energy stored in an object due to its motion.

• The energy released when an object falls to the ground.

• The energy required to lift an object to a certain height.

What is an example of energy transformation?

• A light bulb converting electrical energy to light energy.

• A car using gasoline to move forward.

• A roller coaster gaining potential energy as it climbs and converting it to kinetic energy as it descends.

• A battery storing energy for later use.

What is thermal energy?

• The energy stored in chemical bonds of a substance.

• The total kinetic energy of particles in a substance, which increases with temperature.

• The energy associated with the motion of an object in space.

• The energy required to change the state of a substance.

What is potential energy?

• The energy of an object in motion.

• The energy stored in an object due to its position or state.

• The energy released during a chemical reaction.

• The energy associated with the temperature of an object.

What is the formula for kinetic energy?

• KE = mv

• KE = 1/2 mv²

• KE = mgh

• KE = 1/2 mv

How does energy transform from potential to kinetic?

• Energy transforms from potential to kinetic when an object falls or moves from a higher position to a lower position, converting stored energy into motion.

• Energy transforms from potential to kinetic when an object is at rest and begins to vibrate.

• Energy transforms from potential to kinetic when heat is applied to an object, causing it to move.

• Energy transforms from potential to kinetic when an object is compressed and then released.

How do you calculate gravitational potential energy?

• GPE = mv²

• GPE = mgh

• GPE = m/g

• GPE = mg²h
