What is Kinetic Energy?
|
Movement. Anything that is moving has kinetic energy
|
|
|
What does kinetic energy depend on?
|
Mass and speed. The greater its mass and faster its going, the bigger its KE will be
|
|
|
What's the formula for KE?
|
KE = 1/2 x mass x speed squared
|
|
|
A car with a mass of 2450kg travels at 38m/s what's its KE?
|
1/2 x 2450 x (38 x 38)
1/2 x 2450 x 1444 = 1768900J |
|
|
What does Gravitational Potential Energy depend on?
|
Energy is due to height
|
|
|
What is GPE?
|
Energy stored in an object when raised to a height against gravity (10 m/s squared). It's like storing kinetic energy.
|
|
|
What's the formula for GPE?
|
GPE = m x g x h
mass x gravitational force x height |
|
|
How is stored kinetic energy of GPE released
|
The object falls!!! Falling objects convert GPE to Kinetic. The further it falls the faster it goes
|
|
|
What is the formula for Kinetic energy gained by falling objects
|
KE gained = GPE lost
|
