Question

without changing mass or height what else do u think u could do to design a system in which gpe and ke values are more equal

Answer 1

System with earth at centre and body revolving around it.

Step-by-step explanation:

Given that gravitational and kinetic energy should be nearly equal without changing the mass or height.

So ,

Let us consider a system where we have a body revolving around the earth with a velocity such that it remains in orbit.

Gravitational potential energy at a height h from the ground is given by

`-(GMm)/(R+h)`

`(1)/(2) mv^(2)=(GMm)/(R+h)`

For velocities satisfying abow the system can have gpe and ke same in ideal cases.

[Note: For the abow velocity usually the body will escape as potential at infinity will be zero .This can just be a type of system where gpe and ke will be equal without mass and height changing.]
