Question

Which of the following factors does not affect the potential energy of an object of constant mass
a mass
b gravitational acceleration
c position
c velocity

Answer 1

Mass, because in my opinion gravity, position and velocity cannot be the answer.

1. Gravity -- We all know that it is constant, but it is not necessary that the planet should be Earth it can be Venus, Jupiter or any other planet. And mass is gonna be same anywhere in this universe.
2. Position -- Position means co-ordinate (x, y) indirectly it means height, and in the formula of potential energy is (P = mgH) and as you can see clearly that it is directly proportional to Height, So this concludes that height can affect potential energy of an object.
3. Velocity -- So, this can be a little tricky my friend, It's gonna be simple but tricky!! Velocity is directly proportional to kinetic energy that is,
4. $k.e = \frac{1}{2} m {v}^{2}$

And as we can see clearly that k.e is directly proportional to v^(2), and kinetic energy is inversely proportional to potential energy, From all this we can conclude that velocity is inversely proportional to potential energy. So, it can also affect potential energy of an object.

HAVE A NICE DAY!!!
