If a car collides with a housefly, what will be the magnitude of the force experienced by the housefly?
Correct answer: C. Equal to the force experienced by the car
- A. Much greater than the force experienced by the car
- B. Much less than the force experienced by the car
- C. Equal to the force experienced by the car
- D. Cannot be determined without knowing the masses of the car and the housefly
Explanation
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that when the car collides with the housefly, the housefly exerts an equal force on the car. Therefore, the magnitude of the force experienced by the housefly is equal to the force experienced by the car.

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.
