Kinetic And Potential Energy Flashcards
0
Q
What is a gravitational field
A
Somewhere where gravity acts on an object
1
Q
What is gravitational potential energy
A
Is the energy that an object has because of its height in a gravitational field
2
Q
What happens when an object is vertically lifted
A
Work is done against the force of gravity . The object gains gravitation potential energy
3
Q
What is the equation for working out gravitational potential energy
A
Mass x gravitational field strength x height
Ep= m x g x h
4
Q
What is the gravitational field strength of earth
A
10n/kg
5
Q
What is kinetic energy
A
Energy of movement
6
Q
What does the kinetic energy depend on
A
Mass and speed
7
Q
What is the equation for kinetic energy
A
1/2 x mass and speed2
Ek= 1/2 x m x v 2
