Work + Power Flashcards
1
Q
What are the units of work?
A
The same as the units of energy - joules -J
2
Q
What is work?
A
The Transfer of energy
3
Q
Equation for Work done is?
A
Work Done = Force x Distance Moved W.d = Fxd
Force is measured in Newtons - N
Distance moved is measured in metres - M
Work done is measured in joules - J
4
Q
What is power?
A
Power is the rate of doing work
5
Q
What does a powerful engine do compared to a less powerful engine?
A
does work (transfers energy) much faster
6
Q
Equation for Power is?
A
Power = Work done/ time taken P = W.d/t
⚫ Time is measured in seconds (s).
⚫ Power is measured in watts (W).
⚫ Work done is measured in joules (J).
