Question

A new process converts potential energy of an object to kinetic energy. Neither work nor heat is added to the system. No reaction takes place. What determines the velocity of the object? Change in height of the object All of the above Not sure Mass of the object Elevation of the process

Answer 1

Answer:

Change in height of the object

Explanation:

Change in height of the object

Since ,

We know potential energy can be written as mgh where

P.E. = mgh

M = mass ,

g = gravity constant

h = height

Kinetic energy can be written as 0.5 mv²

So , the Potential energy = kinetic energy

Then ,

velocity of object = √2 gh

Since g is a constant ,

Hence ,

Height of object will determine the velocity.
