Which formula defines Force in this material?

• A. Mass x Velocity
• B. Acceleration x Distance
• C. Mass x Acceleration
• D. Force equals work done

Answer: (C)

Newton's second law: the force acting on an object equals its mass times the acceleration it experiences. This means how hard you push depends on how heavy the object is and how quickly you want it to speed up, expressed as F = ma. For example, a 3 kg cart accelerated at 4 m/s^2 requires 12 Newtons of force. The other ideas mix different concepts: velocity is speed with direction, not force; mass times velocity would give momentum, not force; acceleration times distance isn’t a direct definition of force; and equating force to work confuses energy transfer with the cause of motion. So mass times acceleration is the correct relationship.
