physics equation sheet paper one 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
power
A
power = work done / time = energy / time power = (current)²x resistance power = potential difference x current
5
Q
efficiency
A
efficiency = useful output /input
6
Q
charge
A
charge = current x time
7
Q
potential difference
A
potential difference = current x resistance
8
Q
energy transferred
A
energy transferred = charge flow x potential difference
9
Q
density
A
density = mass/volume
