Question

two rocks A and B of masses 100 kg and 20 kg respectively are setting at anedhe of a cluff. which rock has a higher potential energy? when the rocks are made to fall on the ground, which Rock will make a deeper impression on the ground? give reason​

Answer 1

Answer:

because PE=mgh

rock A has the higher potential energy

Explanation:

When fell, rock A willmake deeper impression. It is because the Gravitational force is directly proportional to the product of mass of the two objects.

Answer 2

Explanation:

rock a has higher potential energy because the gravitational force is directly proportional to the product of mass of the two objects. and rock a make also makes deeper impression because Rocky has more mass that's why Rocky has more potential energy.
