Question

if a ping pong ball and a basketball were both dropped at the same time from the roof of our school, which would hit the ground with a greater force? common sense tells us that the basketball ball would. the difference in forces would be caused by the different masses of the balls. newton stated this relationship in his second law, the force of an object is equal to its mass times its acceleration.
list two other situations where newtons 2nd law may apply.

Explanation:

Newton's second law ($F = ma$) applies in various situations. For example, when a car accelerates, the force exerted by the engine ($F$) is related to the car's mass ($m$) and its acceleration ($a$). Another example is when a person pushes a shopping cart. The force applied to move the cart ($F$) depends on the cart's mass ($m$) and how quickly it accelerates ($a$).

Answer:

1. A car accelerating: Force from engine = mass of car × acceleration of car.
2. Pushing a shopping cart: Force applied = mass of cart × acceleration of cart.
