If no force is acting on a body, can it have any energy? Explain.?

Answer 1

It has POTENTIAL energy!

Why?
Because:
A body is material, since it has mass!
Matter has energy (law of conservation)

Answer 2

If this is a question in the physics of dynamics, then the answer is yes if it is in motion. Potential energy only exists if a force acts on the body, such as gravity. A brick on a ladder on earth has potential energy, in outer space not. Never mind E=mc^2

Answer 3

Certainly, but said body must be moving

Since you specified that there were no external forces we must put said body in deep space. Then since you're asking if it can have energy, we must allow for motion.

Then since Newtonian energy is 1/2mv^2 - and as said body has mass and velocity, it therefore has energy.

Straight facts, simple logic (as Spock was fond of saying)

Answer 4

There is always energy on the molecular level of things. There is no KINETIC energy if there is no force acting on the body.

Answer 5

One basic form of all bodies on our planet have is kinetic energy. This comes from the rotation of our planet on its axis, also from its movement about the sun. Even though we do not realize it, everyone and everything has this form of energy in abundance within them.

Answer 6

You need to give more information. It could have Potential Energy. By "no force," do you mean gravity as well?

Answer 7

yes it can have energy stored in it as internal energy like electronic energy, nuclear energy, potential energy transitional energy, vibrational energy, rotational energy etc.

Answer 8

yes it has internal energy due to it's molecular confriguation and molecular motion
