Answer (3)
The energy an object has is due to it's Kinetic Energy. ;
Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula K.E. = 0.5 * mass * velocity^2. ;
The energy an object possesses due to its motion is called kinetic energy, defined mathematically as K E = 2 1 m v 2 . Kinetic energy depends on the mass of the object and the square of its velocity, meaning that it increases significantly with speed. This concept is crucial for understanding various physical phenomena in real-world scenarios.
