Question

when a body falls ,then its total energy. hint: (consider the law of conservation of energy). a) increases. b) first increases. c) decreases d)remain constant​

Answer 1

Answer:

b

Explanation:

Since, total energy of the system is always conserved, so when a body falls freely towards the earth, then its total energy remains constant i.e., the sum of the potential energy and kinetic energy of the body would be some at all points.

Answer 2

Answer:

option d) remain constant ✓✓ is correct

Explanation:

Since, total energy of the system is always conserved, so when a body falls freely towards the earth, then its total energy remains constant i.e., the sum of the potential energy and kinetic energy of the body would be same at all points.
