Step-by-step explanation:
Yes, it is possible for an object's kinetic energy to suddenly decrease. Kinetic energy (KE) is directly related to an object's speed (v) and mass (m) through the formula:
KE = (1/2) * m * v^2
If the mass remains constant and the kinetic energy decreases, it means the square of the speed (v^2) must decrease. This implies that the speed (v) of the object must decrease.
In other words, if an object's kinetic energy decreases, it indicates that the object is slowing down or losing speed. Factors such as friction, air resistance, or external forces can cause a reduction in an object's kinetic energy by decreasing its speed.
