Question

An object which has a mass of 70 kg is sitting on a cliff 10 m high. Calculate the object's Potential energy. Given g = 10m/s2

Question 16 options:

a) 7,000 Joules
b) 3,500 Joules
c) 70 Joules
d) 35 Joules
e) 700 Joules

Answer 1

Answer is a.)

Given: Mass m = 70 Kg Height h = 10 m; g = 10 m/s²

Required. Gravitational Potential Energy or P.E

Formula: P.E = mgh

= (70 Kg)(10 m/s²)( 10 m)

P.E = 7,000 Kg.m²/s² or

P.E = 7,000 J
