Explain how the kinetic energy of an object changes when the speed of the object doubles?

Kinetic energy is (1/2) (mass) (speed)2 .
The only part of that formula we need in order to answer the question is
the (speed)2 part. It says that if you multiply the speed by 'K', then the
kinetic energy gets multiplied by K2 .
So if you double the speed, the kinetic energy is multiplied by (2)2 = 4 .

How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
What is the theory used to explain changes in state?
The answer is Kinetic Theory or Kinetic Moleculer Theory
Does kinetic energy increase or decrease when a liquid changes to a gas?
the kinetic energy increases
What are the energy changes in a catapult?
kinetic energy to gravitational potential energy
When kinetic energy changes into potential energy it undergoes an energy?
An energy transformation.

If the of an object doubles Its kinetic energy doubles?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
What is the theory used to explain changes in state?
