Question

# Find the potential energy of a body if a body of mass 10 kg is falling from a height of 10 m.

- 900J
- 950J
- 980J
- 1000J

Hint:

### Potential energy= mass x gravitational acceleration x height.

## The correct answer is: 980J

### Given,

mass of the object = 10 Kg

Height from which the object is falling = 10 m

According to the formula,

Potential energy= mass x gravitational acceleration x height.

PE = 10 x 9.8 x 10 ( gravitational acceleration = 9.8m/s^{2})

PE = 980J
