If a car collides with a housefly, what will be the magnitude of the force experienced by the housefly?
Correct answer: C. Same as the force experienced by the car
- A. Much greater than the force experienced by the car
- B. Much lesser than the force experienced by the car
- C. Same as the force experienced by the car
- D. 10 times less than the force experienced by the car
Explanation
The force experienced by the housefly and the car must be equal in magnitude due to Newton's Third Law, which states that every action has an equal and opposite reaction. Even though the fly is much lighter and suffers more damage, the force pair is the same. Therefore, the force on the fly is equal to the force on 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.
