All The Equations You Need To Learn

speed = distance/time taken
acceleration = change in velocity/time taken
density =mass/volume
momentum= mass x velocity
work done=force x distance moved in direction of force
power = energy transferred/time taken = work done/time taken
weight= mass x gravitational field strength
kinetic energy= ½ x mass x speed2
change in potential energy= mass x gravitational field strength x change in height
