What factor does not change when the mass of an object is increased while keeping its velocity constant?

• A. Kinetic energy
• B. Momentum
• C. Weight
• D. Inertia

Answer: (D)

When the mass of an object is increased while keeping its velocity constant, the factor that does not change in the context of dynamics is inertia. Inertia refers to an object's resistance to changes in its motion, which is directly associated with its mass. Therefore, as mass increases, the inherent property of inertia also increases proportionally. Inertia is defined as the ability of an object to resist acceleration when a force is applied; it is fundamentally linked to the mass itself. Consequently, if the mass increases, the extent of the inertia increases as well, but the property defining the resistance to motion (inertia) remains the same – it reflects the object's mass. On the other hand, kinetic energy, momentum, and weight are all dependent on the mass. For example, kinetic energy increases with mass since it is calculated using the formula \( KE = \frac{1}{2} mv^2 \), thus changing as mass increases while velocity remains constant. Similarly, momentum, defined as \( p = mv \), also changes because it is directly proportional to mass. Weight, defined as the gravitational force acting on an object, is calculated as \( W = mg \), showing that it too increases with mass. Therefore, while inertia increases with mass
