A 50kilogram object is located 5metre above the ground level. Find its potential energy.
Step 1: Given data:
Mass,m=50kgheight,h=5mAccelerationduetogravity,g=9.8m/s2
Step 2: Find the potential energy
P.E=mghP.E=50×9.8×5P.E=2450J
Hence, the potential energy is 2450J.
6. An object of mass 40 kg is raised to a height of 5 m above the ground. . What is its potential energy? If the object is allowed to fall, find its kinetic energy when it is just above the ground
Calculate the potential energy of an object of mass 50 kg resied to a height of 4m above the ground. If the object falls down, what is its kinetic energy when it has fallen through 2m? (take g-10m/s2)
_______ energy possessed by an object is directly proportional to its height above the ground level
