Will potential energy of a body will increase or decrease if we bring that body closer to the earth ???

Answers (1)

if a body of mass m is moved from  r_{1 } to r_{2 }

Then Change of potential energy is given as

 \Delta U=GMm\left [ \frac{1}{r_{1}}-\frac{1}{r_{2}} \right ]

If r_{1}>r_{2} then the change in potential energy of the body will be negative.

So potential energy of a body will decrease if we bring that body closer to the earth.
