Question 8 of 29

Which of the following is an example of Newton's second law of motion?
OA. A wheelbarrow is more difficult to move as more objects are
placed inside.
OB. When a gymnast jumps off the ground, Earth also exerts a force
on the gymnast.
OC. Rocks lose energy as they roll down a hillside.
OD. A satellite in space can travel without slowing down, even after
using up all its fuel.

Answer 1

Option A

Step-by-step explanation:

In reality what they are trying to say, is that we need to exert more force to accelerate a wheelbarrow that has more mass.

In other words, when mass increases the force exerted to maintain an acceleration increases as well, and this is given by newton's second law of motion, which suggests that the force exerted on a system is proportional to the mass of that system.
