How is impulse derived from the force of impact equation without using calculus?

• By dividing the net force by the change in time.

• By multiplying the change in momentum by the change in time.

• By multiplying the net force by the change in time.

• By taking the derivative of momentum with respect to time.

In the calculus-based derivation, what does the integral of the net force with respect to time represent?

• The instantaneous momentum.

• The change in velocity.

• The change in momentum.

• The average force.

What does the area under a force versus time curve represent?

• The net force applied.

• The change in velocity.

• The impulse.

• The work done.

Why might the impulse calculated using the average force (F_avg * Δt) differ from the impulse calculated as the area under the force-time curve, especially for short impacts?

• The average force method only applies to constant forces.

• The force platform's data sampling frequency might be too low to accurately capture the peak force.

• The area under the curve method is only for elastic collisions.

• The change in time (Δt) is difficult to measure accurately.
