Question
If an object of mass 1 kg is falling from a height of 8 m, then find the potential energy of the object (g=10 m/s2).
- 60
- 70
- 80
- 100
Hint:
Potential Energy= 
The correct answer is: 80
- Potential Energy=
- where m= mass,
- g= acceleartion due to gravity (10
)
- h= height
- so P.E=1.8.10=80 Joule
