What is kinetic energy?

Question

hi, what is kinetic energy, and also how can i get it?

Answer 1

Well kinetic energy is movment energy soo you can get it anyway you move

Answer 2

energy of motion

Answer 3

KE = 1/2 m*v*v (in joules)

a stationary object has no KE, until you accelerate it, which requires force (F = ma)

m = mass

v = velocity

a = acceleration

(Aside: totally random movement (KE?) by individual atoms/molecules is actually thermal energy or heat!  KE, on the other hand, involves many many many atoms/molecules moving as a whole.  Its a macroscopic effect!)

Answer 4

Energy due to Molecular Motion WITHIN a substance and, Motion OF a substance. (Physical movement).

You already have it within you and when you are moving.

The formula is: KE = ½mv²

Answer 5

"Kinetic energy is the energy of motion.  An object which has motion - whether it be vertical or horizontal motion - has kinetic energy.  There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another)."(http://www.glenbrook.k12.il.u... par 1)   "Kinetic energy is a scalar quantity; it does not have a direction."(http://www.glenbrook.k12.il.... par 3)  In order to get kinetic energy, you must have potential energy.  Potential energy turns into kinetic energy when you have movement.  Hope this helps.  I got most of it from the website below.

Answer 6

Movement.
