The product of force and time is equal to:
Correct answer: C. Change in momentum
- A. Angular momentum
- B. Force
- C. Change in momentum
- D. Velocity
Explanation
The correct answer is C: Change in momentum. According to Newton's second law, when a constant force is applied over a time interval, it results in a change in momentum represented by the equation F * t = Δp. Here, F is the force applied, t is the time duration over which the force is applied, and Δp is the resulting change in momentum. The other options are incorrect because: A) Angular momentum relates to rotational motion and does not stem from this equation; B) Force cannot equal the product of itself and time; D) Velocity is a measure of speed in a specific direction and does not directly relate to the force-time product.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
