Potential vs Kinetic Energy

Energy is never created or destroyed... only transferred between potential and kinetic energy.

by Mr. Arch

What is Kinetic Energy?

Kinetic Energy is energy of motion.
An object gets kinetic energy from its mass and velocity. An object with kinetic energy has energy stored in motion.

Kinetic Energy

KE is the energy of motion

The amount of Kinetic energy is dependent on the mass and velocity of an object.

Multiple Choice

What is kinetic energy?

the energy an object has because its moving

the energy an object does not have because its moving

the energy an object sometimes has because its moving

the energy an object never has because its moving

Multiple Choice

Kinetic energy depends on

mass and height

height and speed

mass and speed

mass and force

Potential Energy

Potential Energy is energy of position.
An object gets potential energy from height, mass and gravity.
An object with potential energy has the potential to do work. This potential is only released when the object falls.

Potential Energy

Stored energy

The energy of position

The amount of energy contained in an object at rest

Multiple Select

What variables determine the amount of PE an object has?

Energy/Force

Position/Height

Gravity

Mass

Multiple Select

What variables determine the amount of KE an object has?

Mass

Gravity

Speed

Potential Energy

Multiple Choice

Which point has the most potential energy?

at point A

at point F

at point B

at point G

Multiple Choice

At which point is potential energy least?

Multiple Choice

Look at the picture. Which of these has the least potential energy.

Potential and Kinetic Energy

Notice that as the kinetic energy increases the potential energy decrease.

When the coaster goes back up the hill the energy is converted back to potential energy.

Formula for finding kinetic energy

Energy has a unit of Joules (J).

Multiple Choice

You serve a volleyball with a mass of 2 kg.

The ball leaves your hand with a speed of 30 m/s.

The ball has kinetic energy.

Calculate it.

60 J

1800 J

900 J

Multiple Choice

A car is traveling with a velocity of 20 m/s and has a weight (mass) of 1000 kg. What type of energy does the car have?

kinetic

potential

Formula for finding potential energy

m is the mass, h is the height and g is acceleration of gravity (g)= 10

Multiple Choice

A baby carriage is sitting at the top of a hill that is 20 m high.

The carriage with the baby in it weighs 40 kg.

Calculate how much potential energy the carriage with baby has?

800 J

8000 J

80 J

Open Ended

What is the difference between kinetic energy and potential energy?

Type response here

Open Ended

The Law of Conservation of Energy states, "Energy is never created or destroyed only change." How does the relationship between potential and kinetic energy illustrate this?

Type response here
