Kinetic and Potential Energy

What is kinetic energy?

• Energy stored in an object due to its position

• Energy released from the sun

• Energy an object possesses due to its motion

• Energy produced by an object at rest

Define potential energy.

• Energy due to position or state

• Energy due to motion

• Energy due to temperature

• Energy due to color

How is kinetic energy calculated?

• KE = 0.5 * mass * velocity^2

• KE = mass + velocity

• KE = mass * velocity

• KE = mass / velocity

Explain the concept of gravitational potential energy.

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

• The energy produced by the movement of an object

• The energy stored in an object due to its temperature

• The energy stored in an object due to its speed

What are some examples of potential energy being converted to kinetic energy?

• Sitting on a chair, book on a desk, rubber band on a wrist

• Roller coaster car going down a hill, book falling off a table, stretched rubber band being released, pendulum swinging back and forth

• Car parked on a hill, book on a shelf, rubber band on a table

• Car going uphill, book floating in water, rubber band being stretched further

What is the formula for calculating potential energy?

• PE = mgh

• PE = mgh^2

• PE = 2mgh

• PE = m^2gh

Describe the relationship between kinetic and potential energy.

• They are completely separate forms of energy

• Kinetic energy is always greater than potential energy

• They are interrelated and can be converted into each other.

• They have no relationship

How does an object's mass and speed affect its kinetic energy?

• Only mass affects the kinetic energy of an object

• Only speed affects the kinetic energy of an object

• Neither mass nor speed affect the kinetic energy of an object

• Both mass and speed affect the kinetic energy of an object.
