Question

You push really hard against a round rock, but you cannot make it roll. Which statement best explains why you cannot move the rock

Answer 1

Answer:

b

Explanation:

a Gravity pulls the rock toward the center of Earth.

b The forces between you and the rock are balanced.

c The force of your push is greater than the opposing force.

d There is no friction to help you move the object.

The correct answer would be that the forces between you and the rock are balanced.

In order to get the rock rolling, both the frictional force between the rock and the surface on which it stands as well as the gravitational force acting on its mass must be exceeded. If the applied force balances these forces or falls short, the rock will not move.

The correct option is b.
