CALCULATE THE WORK DONE WITH A FORCE OF 15N AND 10M GIVEN THAT IT TOOK 15MINS FIND THE POWER
HOW TO CALCULATE KINETIC ENERGY
HOW TO CALCULATE POTENTIAL ENERGY
Work done = Force x Distance
Work done = 15N x 10m
Work done = 150 Joules
Power = Work done / Time
Power = 150J / (15min x 60s/min)
Power = 150J / 900s
Power = 0.167 Watts
To calculate kinetic energy:
Kinetic Energy = 0.5 x mass x velocity^2
To calculate potential energy:
Potential Energy = mass x gravity x height
