Question

consider this situation: a team of landscapers grab the root ball of an unplanted tree and drag it across the lawn. of the forces listed, identify which act upon the tree. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

• Normal force: The lawn exerts a normal force (perpendicular to the surface of the lawn) on the tree to support its weight.
• Gravity: The Earth's gravitational pull acts downward on the tree.
• Applied force: The landscapers are applying a force to drag the tree.
• Friction: As the tree is dragged across the lawn, there is frictional force (opposing the motion) between the tree and the lawn.
• Tension: If the landscapers are using ropes to drag the tree, tension forces act along the ropes.
• Air Resistance: Although relatively small compared to other forces in this situation (assuming slow - moving tree), air resistance still acts on the tree as it moves through the air.

Answer:

Normal, Gravity, Applied, Friction, Tension, Air Resistance
