In Newtonian mechanics the formula is:
E = 1/2 m v^2
Where E is the kinetic energy, m the mass of an object and v its velocity.
If the speed approaches that of light a different formula should be used according to special relativity:
E = (gamma - 1) m c^2
Here c is the speed of light and gamma is the gamma factor given by: 1 / sqrt(1-sqr(v/c)).

What is the formula for calculating mechanical energy?
Mechanical energy is the sum of potential energy + kinetic energy.
How do you find an object's mechanical energy?
By calculating and adding its kinetic energy and its potential energy.
What is needed to calculate kinetic energy?
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
What is the fromula for kinetic energy?
Kinetic energy = (1/2)mv^2 Kinetic energy =199295.1 J
Mass is 145g and velocity is 25ms Find the answer using kinetic energy formula?
Kinetic energy is 0.45 joules using the formula Ek = ½ x mv2

Calculating kinetic energy?
Vague question... To calculate the kinetic energy of a moving object you use the formula: Ek = 0.5 * m * V^2 For example: The kinetic energy of a car driving 30 m/s and weighing 800 kg is: 0.5* 800 kg * 30^2 m/s = 360000 joules
How does the formula of kinetic energy define?
kinetic energy is defined as the energy possessed by a body by virtue of its MOTION Formula ;Ek=0.5xmassx(velocity)to the square
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.
Formula for total energy?
kinetic energy+potential energy=total energy
What are the formulas for kinetic energy?
The formula for kinetic energy is KE = 1/2(mass)(velocity squared)
What is the formula for kinetic energy and what it stands for?
The formula for kinetic energy is KE = 1/2mv2, where m is mass in kg and v is velocity in m/s.
What is needed to calculate kinetic energy?
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
