Equations to learn

HideShow resource information
Distance-time graphs
speed (m/s) x time (s) = distance (m)
1 of 11
Velocity-time graphs
acceleration (m/s-squared) x time (s) = final velocity (m/s) - initial velocity (m/s)
2 of 11
Resultant force
mass (kg) x acceleration (m/s-squared) = force (N)
3 of 11
Work done
force (N) x distance moved in the direction of the force (m) = work done (J)
4 of 11
Kinetic energy
1/2 mass (kg) x velocity-squared = kinetic energy
5 of 11
Momentum
velocity (m/s) x mass (kg) = momentum (kg/m/s)
6 of 11
Conservation of momentum in an explosion
Before = 0; After = 0
7 of 11
Changing momentum
force (N) x time (s) = change in momentum (kg/m/s)
8 of 11
Resistance
potential difference (volts) x current (amperes) = resistance (ohms)
9 of 11
Mains electricity
frequency (hertz) x time peroid (s) = 1
10 of 11
Power of an appliance
power x time = energy transferred
