If an object is moving with a constant velocity and no acceleration, its kinetic energy remains constant. The kinetic energy (KE) of an object can be calculated using the formula:
KE = 0.5 * m * v^2
where: KE is the kinetic energy, m is the mass of the object, v is the velocity of the object.
Since the object is moving with a constant velocity and no acceleration, the velocity (v) remains constant. Therefore, the kinetic energy (KE) would also remain constant as long as the velocity is unchanged.
