Work done meaning
Transfer of energy (only when you cause movement)
Work done, force, distance formula
Work done= force x distance moved (in direction of force)
Power, work done, time equation
Power = work done/ time
Power meaning
The rate of transfer of energy (or doing work)
Force, mass, acceleration equation
Force = mass x acceleration
Newtons 2nd law
The force applied and the acceleration are directly proportional
Describe how terminal velocity occurs
at the point of release the only force acting on the object is weight
This unbalanced force causes acceleration
As acceleration and speed increases, drag increases
Eventually the drag force is equal to weight and the forces are balanced
This causes the object to travel at a constant speed called terminal velocity
