Question

when the force on an object increases, so does its __________. a. acceleration b. velocity c. mass d. inertia please select the best answer from the choices provided. a b c d

Explanation:

According to Newton's second law of motion, \( F = ma \) (where \( F \) is force, \( m \) is mass, and \( a \) is acceleration). If the mass \( m \) of an object is constant, when the force \( F \) increases, the acceleration \( a \) must also increase (since \( a=\frac{F}{m} \)).

• Option B: Velocity is not directly proportional to force in a simple way; force affects acceleration, which then affects velocity over time, but velocity doesn't necessarily increase just because force increases (e.g., if the force is in the opposite direction of motion, it could decrease velocity).
• Option C: Mass is a property of the object and does not change with the applied force (in classical mechanics, for non - relativistic cases).
• Option D: Inertia is related to mass, so it also does not change with the applied force.

So the correct answer is A as acceleration is directly proportional to the net force acting on an object (when mass is constant).

Answer:

A. acceleration
