P2 - Work Done And Potential Energy Flashcards
1
Q
What is the formula for work done?
A
Work done = Force (N) x Distance (m)
2
Q
What is the formula for gravitational potential?
A
GP (J) = mass x G x H
3
Q
What is the gravitational field strength on Earth?
A
10N per 1kg.
4
Q
What is the relation between work done and gravitational potential energy?
A
When an object moves vertically upwards, work is done against gravity.
5
Q
What is work done?
A
When forces move an object through a distance and energy is transferred.
