Question

consider this situation: a child pulls a sled by a rope across the lawn at a constant speed. of the forces listed, identify which act upon the sled. tap to select the forces that are present. normal gravity applied friction tension air resistance check answers

Explanation:

1. Gravity: Always acts on objects near Earth, pulling the sled down.
2. Normal: The lawn exerts an upward normal force to balance gravity.
3. Applied: The child’s pull (via rope) is an applied force.
4. Friction: Since the sled moves on the lawn, kinetic friction opposes motion.
5. Tension: The rope exerts tension force on the sled.
6. Air Resistance: As the sled moves, air resistance acts against its motion.

Answer:

A. Normal, B. Gravity, C. Applied, D. Friction, E. Tension, F. Air Resistance
