Energy Forms

What is potential energy?

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

• The energy of motion in an object.

• The energy released during a chemical reaction.

• The energy required to change the temperature of an object.

What is kinetic energy?

• The energy of an object at rest.

• The energy of an object in motion.

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

• The energy released during a chemical reaction.

What is the relationship between height and potential energy?

• The higher an object is, the greater its potential energy due to the gravitational force acting on it.

• Height has no effect on potential energy.

• Potential energy decreases as height increases.

• Potential energy is only dependent on the mass of the object.

What is gravitational potential energy?

• The energy an object possesses due to its speed.

• The energy an object possesses because of its height above the ground.

• The energy stored in an object due to its mass alone.

• The energy an object possesses due to its temperature.

What is the formula for calculating kinetic energy?

• KE = 1/2 mv²

• KE = mv

• KE = mgh

• KE = 1/2 mv

At what point does a roller coaster have the highest kinetic energy?

• At the highest point of the track

• At the lowest point of the track

• At the midpoint of the track

• At the starting point of the track

What is the principle of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be transformed from one form to another.

• Energy is a finite resource that can be depleted.

• Energy can be converted into matter.

What is elastic energy?

• The energy stored in an object when it is heated.

• The potential energy stored in an object when it is stretched or compressed, such as in a rubber band.

• The energy released when an object is dropped from a height.

• The kinetic energy of an object in motion.

How does energy transform between potential and kinetic energy?

• Energy transforms from potential to kinetic energy when an object moves from a higher position to a lower position.

• Energy remains constant regardless of the object's position.

• Kinetic energy is always greater than potential energy.

• Potential energy is converted to thermal energy during motion.

How can you increase the potential energy of an object?

• By lowering its height

• By increasing its mass

• By increasing its speed

• By reducing its weight
