Kinetic and Potential Energy

At which point is Kinetic Energy greatest in a pendulum?

• At the highest point of the swing (position A)

• At the lowest point of the swing (position X)

• At the midpoint of the swing (position B)

• At the starting point of the swing (position C)

What is Kinetic Energy?

• The energy an object possesses due to its motion.

• The energy stored in an object at rest.

• The energy required to lift an object against gravity.

• The energy released during a chemical reaction.

What happens to Elastic Potential Energy when a spring is compressed?

• It decreases.

• It remains the same.

• It increases.

• It becomes kinetic energy.

What is the formula for Kinetic Energy?

• KE = mv

• KE = 1/2 mv²

• KE = mgh

• KE = 1/2 mv

What is Gravitational Potential Energy?

• The energy an object has due to its height above the ground, calculated as mass x gravity x height.

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

• The energy an object has due to its temperature.

• The energy released during a chemical reaction.

What is Elastic Potential Energy?

• The energy stored in elastic materials as the result of their stretching or compressing.

• The energy produced by moving objects.

• The energy stored in chemical bonds.

• The energy released during nuclear reactions.

How does height affect Potential Energy?

• The higher an object is, the more Gravitational Potential Energy it has due to its position.

• Height has no effect on Potential Energy.

• Potential Energy decreases as height increases.

• Potential Energy is only affected by mass, not height.

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 transferred but not transformed.

What is the relationship between mass and Kinetic Energy?

• Kinetic Energy decreases with an increase in mass.

• Kinetic Energy remains constant regardless of mass changes.

• Kinetic Energy increases with an increase in mass; if mass doubles, Kinetic Energy also doubles if speed remains constant.

• Kinetic Energy is independent of mass and depends only on speed.

In which position does a spring lose its Elastic Potential Energy?

• When it is fully compressed

• When it is fully stretched

• When it returns to its natural length (position X)

• When it is at half its length
