Original Project
Force and Motion
A force is a push or a pull between two objects.
Item FM054002: For a tire swing hanging from a tree, both the force of gravity and the force of the rope on the tire are forces acting on the tire.
A tire swing can be made by tying a car tire to a rope and then tying the rope to a tree branch. What are the forces acting on the tire in the tire swing shown below?
- Only the pull of the rope on the tire
- Only the pull of earth’s gravity on the tire
- Both the pull of the rope on the tire and the pull of earth’s gravity on the tire
- Neither the pull of the rope on the tire nor the pull of earth’s gravity on the tire
