Arrange the balls in order from greatest amount of gravitational potential energy to least.
2 answers:
Answer : Gravitational potential energy is greatest in A while least in D.
Explanation :
When an object raised through a certain height then its energy increases because work is done against gravity. The energy associated with such type of object is called as the gravitational potential energy.
The formula for gravitational potential energy is :
PE = m g h
where,
m is the mass of an object
g is acceleration due to gravity
h is the height attained by the object
When height tends to zero, the gravitational potential energy also becomes zero.
In the given figure, ball A is at the maximum height and ball D is at minimum height. So, potential energy in ball A is maximum and in ball B is least
So, the correct order is
