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).
The toy car starts moving because it has acquired energy from the winding action, which enables it to do work and move.
The unit of energy is the joule (J), which is the amount of energy required to do one joule of work.
The second object receives the energy, may move, and performs work, demonstrating the first object’s capacity to do work.
An object with energy can exert a force on another object, transferring energy to it, causing it to move and thus do work.
