No, an object cannot have kinetic energy if it is not in motion. Kinetic energy is explicitly tied to the motion of an object. The kinetic energy (KE) of an object is given by the formula KE = 0.5 × mass × velocity², where velocity is the speed of the object. When an object is at rest (velocity equals zero), its kinetic energy becomes zero as well. Kinetic energy arises from the movement of particles within or the entire object itself. Without motion, there is no kinetic energy, and any previous kinetic energy is converted or dissipated through other forms of energy.

The kinetic energy (KE) of an object with mass (m) and velocity (v) is calculated using the formula: KE = 0.5 × m × v². In this equation, 0.5 represents the constant factor and is included to account for the relationship between kinetic energy and velocity squared. The mass of the object is multiplied by the square of its velocity, and the result is divided by 2. This formula demonstrates that kinetic energy increases with both mass and the square of velocity. It quantifies the energy associated with an object’s motion, providing a useful tool for understanding and analyzing dynamic systems.

The equation demonstrates that the final velocity squared is equal to the sum of the initial velocity squared (u²) and twice the product of acceleration (a) and displacement (s).

If the acceleration of an object is zero, its velocity remains constant. According to Newton's first law of motion, an object at rest stays at rest, and an object in motion continues at a constant velocity unless acted upon by a net external force.

If the acceleration of an object is zero, its velocity remains constant. According to Newton’s first law of motion, an object at rest stays at rest, and an object in motion continues at a constant velocity unless acted upon by a net external force. When acceleration is zero, there is no net force acting on the object, so it maintains its current state of motion. If the object is at rest, it remains at rest; if it is in motion, it continues moving at a constant speed in a straight line. In summary, zero acceleration implies a lack of change in velocity.
