Question

1. Write the formula of potential energy​

Answer 1

Answer:

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

Answer 2

• We have the formula of mechanical energy that depends on the force engaged on the 2 objects. For the attractive force.
• the formula is$P.E. = mgh$, wherever m is that the mass in kilograms, g is that the acceleration thanks to gravity (9.8 m / s2 at the surface of the earth), and his that the height in meters.
• As we know that it depends upon the relative position of varied components of a system mechanical energy keeps that energy.
• The spring has additional mechanical energy once it's compressed or stretched.  
• As we know a steel ball has additional mechanical energy raised higher than the bottom than it once falls to Earth.
