A number of equations exists, but the ones listed below are some of the most common ones. If the velocity of an object is much smaller than the speed of light, use one of these:
E = 1/2mv2
E = p2/2m
E = 1/2Iω (for rotational kinetic energy)
where:
ω = angular velocity
I = moment of inertia
p = momentum
m = mass v = velocity

The formula above would give:
[J] = [m/s]*[s2] WHICH IS INCORRECT!
The correct equation is:
Ekin= 1/2 * m * v2 = 1/2 * [kg] * [m2/s2] = [N]*[m]= [J]

Which is the correct equation for kinetic energy?
Kinetic Energy = (1/2) x (Mass) x (Velocity)2
How can the work-kinetic energy theorem explain why the force of sliding friction reduces the kinetic energy of a particle?
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
What forms of energy does a moving car have?
a moving car has kinetic energy which is defined by the equation "Kinetic Energy = (1/2) X Mass (Kilograms) X (Velocity (m/s))2
Which is the best term to use when describing the energy of motion?
The energy that comes from an object's motion is called kinetic energy. The object's kinetic energy can be found by using the equation K=1/2mv2 which means that kinetic energy is equal to one-half of the object's mass multiplied by the square of its speed.
You can calculate kinetic energy by using the equation what?
KE=1/2*m*v2whereKE is kinetic energym is the massand V is the velocity
What is the kinetic energy of the emitted electrons when the cesium is exposed to UV rays of frequency 1.1times 1015Hz?
Before you can do anything with kinetic energy, you must know the kinetic energy equation. The equation for kinetic energy KE=hv-hv0.
What factors determine an object's kinetic energy?
Look at the equation for kinetic energy. It clearly shows that the kinetic energy depends on the object's mass, and its speed.
Which is the correct equation for kinetic energy?
Kinetic Energy = (1/2) x (Mass) x (Velocity)2
How does speed affect a rollet coaster?
it has more kinetic energy. if this is a problem for school, use the equation for kinetic energy.
What objets has kinetic energy?
kinetic energy is the energy an object has by virtue of its motion- therefore any object that is moving possesses kinetic energy ( and the kinetic energy is proportional to both the mass of the object and the object's velocity, according to the equation KINETIC ENERGY= 1/2 mv2)
Where velocity is squared in the kinetic energy equation doubling an object's velocity will do what to its kinetic energy?
Multiply it by 4 (4 = 22)
Do you have an equation to calculate kinetic energy?
KE=1/2mvsquared
What does kinetic energy depend on in addition to speed?
Kinetic energy can be expressed by the equation: Ek= ½ mv2. Therefore in addition to speed (v), kinetic energy is also dependent on mass (m).
What equation is used to represent kinetic energy?
kinetic energy =1/2 x m x v x v
What will be the effect on kinetic energy by dubbling the mass?
the defining equation for kinetic energy= 1/2 mv2therefore kinetic energy is directly proportional to mass or as kinetic energy increases, mass increases proportionally (and vice versa).therefore if mass is doubled, the kinetic energy is also doubled.
Formula for mechanical energy?
potential energy+kinetic energy=mechanical energy
What equation use for kinetic energy?
Kinetic energy for a moving object is given as KE=mv 2 where KE is the kinetic energy, m is the mass and v the velocity.
