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 its surface on the tree root - ball to support its weight.
• Gravity: The Earth's gravitational pull acts downward on the tree root - ball.
• Applied force: The landscapers are applying a force to drag the tree root - ball.
• Friction: As the tree root - ball is dragged across the lawn, there is frictional force opposing the motion between the root - ball and the grass.
• Tension: If the landscapers are using ropes or straps to pull the tree root - ball, tension forces will act along those ropes/straps.
• Air resistance: Although relatively small compared to other forces (assuming slow - moving motion), as the tree moves, there is air resistance acting against its motion.

Answer:

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