consider this situation: a father uses a rope to pull a child on a sled 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

Answer

Brief Explanations:

  • Normal Force: The surface (e.g., ground) exerts a normal force perpendicular to its surface on the sled to support its weight.
  • Gravity: The Earth's gravitational pull acts downward on the sled (and the child on it).
  • Applied (Tension): The father pulls the rope, and the tension in the rope is the applied force on the sled.
  • Friction: Since the sled is moving (even at a constant speed), there is kinetic friction opposing the motion between the sled and the surface (assuming it's a non - frictionless surface, which is a reasonable assumption in real - world scenarios).
  • Air Resistance: When the sled is in motion, air molecules exert a resistive force (air resistance) opposite to the direction of motion.

Answer:

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