SUMMARY
The discussion clarifies the distinction between impact force and impulse using a tennis ball as an example. Impact force is defined as the force exerted on the pan of a balance when the ball strikes it, while impulse is the product of that force and the time duration of the impact. According to Newton's second law, impulse is equivalent to the change in momentum of the object, expressed mathematically as FΔt = Δp = mΔv. The conclusion confirms that the correct answer to the posed question is B, referring to the impact force on the pan due to the ball.
