Work, Potential Energy and Kinetic Energy Flashcards
1
Q
What is meant by “work done”?
A
When a force moves an object through a distance, energy is transferred and work is done.
2
Q
How do you calculate the work done?
A
Work done = Force x Distance
3
Q
How do you calculate gravitational potential energy?
A
Gravitational Potential Energy = mass x gravity x height
4
Q
What is the formula for kinetic energy?
A
kinetic energy = 1/2 x mass x speed squared.
5
Q
How do you slow down the kinetic energy of a car?
A
The kinetic energy has to be converted to heat energy as friction causing the temperature to increase.
