Paper 1 Eq Flashcards
1
Q
work done =
A
force x distance
2
Q
kinetic energy
A
0.5 x mass x (speed)
2
3
Q
gravitational potential energy
A
= mass x gravity x height
4
Q
power =
A
work done / time = energy / time
5
Q
efficiency =
A
useful output / input
6
Q
charge =
A
current x time
7
Q
potential difference =
A
current x resistance
8
Q
power
A
= potential difference x current
9
Q
power =
A
power = (current)2x resistance
10
Q
energy transferred =
A
charge flow x potential difference
11
