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 SI Unit: Joule or J (1 J = 1 kg m2/s2) Cgs Unit: Erg (107 erg = 1 J)...
An object can start from rest and acquire velocity. An object can also change its velocity during its motion. Suppose the object moves with a velocity vi, the initial velocity. A force alters its motion such that its velocity changes to vf, which is the final velocity. Then, the change in kinetic energy is, ΔK.E. = ½ mvf2 – ½ mvi2 Now, work is bein...
An object rotating about its axis also has kinetic energy. Its kinetic energy depends on angular velocity and moment of inertia. For rotational motion, the expression for kinetic energy is different from linear motion. The formula is, K.E. = ½ Iω2 Where, I: moment of inertia ω: angular velocity An example of rotational kinetic energyis a merry-go-r...
