Question

What is the potential energy of a 2 kg plant that is on a windowsill 1.3 m high

Answer 1

Answer:

Potential Energy=mgh=2×9.8×1.3=25.48.

Answer 2

Given:

mass =2kg

h=1.3m

Find P.E=?

Formula of potential energy is:

P.E= mvg

where g=9.8m/s²

So P.E = 2 × 9.8 × 1.3

P.E = 25.48J

Hence the potential energy is 25.48J
