phisics equations
weight
weight = mass x gravitational field strength
work done
work done = force x distance
Force applied to a spring
Force applied to a spring = spring constant x extension
distance travelled
distance travelled = speed x time
Acceleraration
acceleration = change in velocity/time taken
resultant force
resultant force = mass x acceleration
momentum
momentum = mass x velocity
kinetic energy
Kinetic energy = 0.5 x mass x (speed)^2
gravitational potential energy
gravitational potential energy = mass x gravitational field strength x height
Power
Power = energy transferred/time
