The work done on an object causes a change in its velocity. Specifically, it changes the object’s velocity from its initial velocity (u) to its final velocity (v) by causing acceleration.
The work done (W) on an object is calculated as the product of the constant force (F) acting on the object and the displacement (s) in the direction of the force, so W = F * s.
To express the kinetic energy of an object in equation form, we consider the object’s mass (m), initial velocity (u), final velocity (v), displacement (s), and the constant force (F) acting on it in the direction of displacement.
The kinetic energy of a moving body is defined as the work done on it to make it acquire its velocity.
An object in motion possesses energy because its motion implies the ability to do work. This energy is termed kinetic energy, and it arises from the object’s velocity and mass. As the object moves, it can transfer this energy to ...
Examples of objects possessing kinetic energy include a falling coconut, a speeding car, a rolling stone, a flying aircraft, flowing water, blowing wind, and a running athlete.
A moving bullet pierces a target by transferring its kinetic energy upon impact. The high speed of the bullet means it possesses significant kinetic energy, which is converted into destructive force upon collision with the target.
Kinetic energy is the energy possessed by an object due to its motion.
A larger unit of energy is the kilojoule (kJ), and 1 kJ equals 1000 joules (J).
