Question

which quantity does not change while freely falling under gravity in vacuum (a) kinetic energy (b) potential energy (c) total mechanical energy (d) total linear momentum

Answer 1

Answer:

total mechanical energy

Explanation:

please make answer in brain list

Answer 2

Answer:

Option C) Total mechanical energy

Explanation:

As the body is falling freely under gravity, the potential energy decreases continuously and kinetic energy increases continuously as all the conservative forces are doing work. So, total mechanical energy (PE+KE) of the body will be constant.
