Question

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

Explanation:

Step1: Analyze gravitational force

The sled is on Earth, so gravity acts down - ward on it.

Step2: Analyze normal force

The ground exerts a normal force on the sled perpendicular to the surface, counter - acting the vertical component of gravity.

Step3: Analyze applied force

The father is pulling the sled with a rope, so there is an applied force.

Step4: Analyze friction force

The sled is moving on a surface, so there is friction between the sled and the surface.

Step5: Analyze tension force

The rope connecting the father and the sled has tension force.

Step6: Analyze air - resistance force

Although the speed is constant and the situation may not imply high - speed motion, air resistance is present when the sled is in motion through the air.

Answer:

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