density=
Mass / Volume
9 of 20
work done=
Force x Distance moved by object
10 of 20
Change in Gravitational Potential Energy=
Mass x Gravitational Field Strength x Vertical height
11 of 20
Kinetic energy =
(mass x (speed)^2 ) / 2
12 of 20
power=
Work done / time taken
13 of 20
energy transferred=
Charge x voltage (ET= Q x V)
14 of 20
Charge =
Current x Time (Q= I x t )
15 of 20
Potential difference (Voltage) =
Current x Resistance (V = I x R )
