On which car there is resultant force?
Correct answer: B. Car moving at constant speed around a bend
- A. Car moving on a straight horizontal road
- B. Car moving at constant speed around a bend
- C. Car moving uphill at a constant velocity
- D. Car that is stationary
Explanation
The correct statement is B. Car moving at constant speed around a bend. In this scenario, there is a resultant force (centripetal force) directed towards the center of the bend, which allows the car to maintain a curved path.

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.
