Work done Flashcards
1
Q
What is work done?
A
- When force makes an object move
2
Q
How are work and energy related?
A
- Energy transferred = work done
3
Q
Formula for work done:
A
Work done = force applied X distance move
W (J) = F (N) X s (m)
4
Q
What happens to work done to overcome friction?
A
- Energy is transferred to the thermal energy stores of objects causing friction and to surroundings.
5
Q
What happens to work done to overcome friction caused by air resistance?
A
- Object falling transfers energy
- Gravitational potential energy + Kinetic energy transfer to thermal energy of object
