average speed
average speed = distance / time
1 of 20
acceleration
acceleration = change in velocity / time
2 of 20
force
force = mass x acceleration
3 of 20
weight
weight= mass x gravitational field strength
4 of 20
momentum
momentum = mass x velocity
5 of 20
momentum
momentum = force x perpendicular distance from pivot
6 of 20
power
power = current x voltage
7 of 20
voltage
voltage = current x time
8 of 20
wave speed
wave speed = frequency x wavelength
9 of 20
refractive index
n = sin I / sin R
10 of 20
efficiency
efficiency = useful energy output / total energy input
11 of 20
work done
work done = force x distance moved
12 of 20
gravitational potential energy
gpe = mass x grams x height
13 of 20
kinetic energy
kinetic energy = 1/2 x mass x speed^2
14 of 20
energy transferred
energy transferred = work done
