Work done
work done = force
work done = force × distance
work done = distance / force
Distance
distance travelled = speed × time
distance = speed / time
distance = time / speed
Acceleration
acceleration = change in speed
acceleration = velocity x time
acceleration = velocity / time
Force
force = mass / acceleration
resultant force = mass × acceleration
force = acceleration / mass
Momentum
momentum = mass × velocity
momentum = velocity / mass
momentum = mass / velocity
Kinetic Energy
KE = mass x speed
KE = speed / mass
KE = 0.5 × mass × speed squared
Wave Speed
wave speed = frequency × wavelength
wave speed = wavelength / frequency
