Question

question 2 of 20
which example illustrates newtons first law?
a. the force of a wheelbarrow on the ground is equal to the force of
the ground on the wheelbarrow.
b. the force of a wheelbarrow on the ground is in the opposite
direction of the force of the ground on the wheelbarrow.
c. a person pushes a wheelbarrow, causing it to move forward.
d. more mass is added to a wheelbarrow, and a larger force is
required to move it.

Explanation:

Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Option A is about forces being equal (Newton's third law). Option B is about action - reaction pairs (Newton's third law). Option C is about force causing motion (Newton's second law \(F = ma\)). Option D shows that more mass (more inertia) requires more force to move, which relates to Newton's first law (inertia is the property of an object to resist changes in its state of motion, and mass is a measure of inertia).

Answer:

D. More mass is added to a wheelbarrow, and a larger force is required to move it.
