Question

consider this situation: a custodian pushes a large crate across the gym floor. of the forces listed, identify which act upon the crate. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

• Normal Force: The floor exerts a normal force perpendicular to its surface on the crate to support its weight.
• Gravity: The Earth's gravitational pull acts downward on the crate.
• Applied Force: The custodian applies a force to push the crate.
• Friction: There is friction (likely kinetic) between the crate and the gym floor opposing the motion.
• Tension: There is no rope or string pulling the crate, so no tension force.
• Air Resistance: Since it's a large crate moving at a likely slow speed in a gym (not high - speed motion), air resistance is negligible.

Answer:

Normal, Gravity, Applied, Friction
