Paper 1 Flashcards
1
Q
Work Done?
A
Work done = force x distance
2
Q
Kinetic Energy?
A
Kinetic Energy = 0.5 x mass x (speed)^2
3
Q
Gravitational Potential Energy
A
Gravitational Potential Energy = mass x gravity x height
4
Q
Efficiency?
A
Efficiency = Useful Output/input
5
Q
Power? (work done and time)
A
Power = work done/time
6
Q
Charge?
A
Charge = current x time
7
Q
Potential Difference?
A
Potential Difference = current x resistance
8
Q
Power? (PD and Current)
A
Power = Potential Difference x current
9
Q
Power (current and resistance)
A
Power = (current)^2 x resistance
10
Q
Energy Transferred?
A
Energy Transferred = charge flow x potential difference
11
Q
Density?
A
Density = mass/volume
