Kinetic energy, form of energy that an object or a particle has by reason of its motion. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.
The kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: where is the mass and is the speed (magnitude of the velocity) of the body. In SI units, mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules.
Kinetic energy is a scalar quantity, not a vector. It takes positive values that depend on two factors – velocity and mass. It cannot be negative since mass cannot be negative. The formula for kinetic energy is given by, K.E. = ½ mv2. Where, K.E.: kinetic energy. m: mass. v: velocity.
The energy of motion is called kinetic energy. It can be computed using the equation K = ½mv² where m is mass and v is speed.
The formula for calculating kinetic energy is an essential tool in understanding the energy associated with an object’s motion. The equation for kinetic energy is given by: \(\begin{array}{l} KE = \frac{1}{2} mv^2 \end{array} \)
Microsoft Teams. Learn what kinetic energy means and how it relates to work. What is kinetic energy? Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work.
The kinetic energy formula defines the relationship between the mass of an object and its velocity. The kinetic energy KE equation is as follows: KE = 0.5 × m × v². where: m — Mass; and; v — Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object.
