Detailed explanation-1: -Kinetic energy is the energy of mass (an object) in motion (moving). The faster an object is moving, the more kinetic energy it has. Any object that is moving has kinetic energy – the moving object has energy because of its motion.
Detailed explanation-2: -Anytime matter is in motion it has kinetic energy. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.
Detailed explanation-3: -The relationship between kinetic energy and speed as a nonlinear (square) proportional relationship (KE ∝ v2) in which: 1. The kinetic energy quadruples as the speed of the object doubles. 2. The kinetic energy decreases by a factor of four as the speed of the object is cut in half.
Detailed explanation-4: -Because the motion of an object depends on how fast it’s traveling, but also how much mass it has, though velocity is the more important factor.
Detailed explanation-5: -Kinetic energy is directly proportional to the square of the speed of the body.
