Question

select the correct answer. a child sits on top of a slide at the park. he pushes forward lightly, but does not go down the slide. pick the sentence that best describes why the child is not moving. earths gravitational force pulls the child down the slide. there are no forces exerted on the child. air is holding the child in place. the net force on the child is zero.

Explanation:

According to Newton's first - law of motion, 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. When the child is not moving, it means the forces acting on the child (such as gravitational force pulling down, normal force from the slide pushing up, and frictional force opposing the motion) are balanced, resulting in a net force of zero.

Answer:

The net force on the child is zero.
