###### 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

## Answers

Answer:Change in height of the objectExplanation:Change in height of the object Since , We know potential energy can be written as mgh where P.E. = mghM = 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.
