Question

consider this situation: a moving car skids to a stop with the wheels locked across a level roadway. of the forces listed, identify which act upon the car. tap to select the forces that are present. normal gravity applied friction tension air resistance

Explanation:

1. Normal force: The road exerts an upward - acting normal force on the car to counteract the force of gravity.
2. Gravity: The Earth's gravitational pull acts downward on the car.
3. Friction: Since the wheels are locked and the car is skidding, kinetic friction acts between the tires and the road surface, opposing the car's motion.
4. Air resistance: As the car is moving, air resistance acts in the opposite direction of the car's motion, although its effect might be relatively small compared to friction in this case. There is no applied force (no external pushing or pulling force other than friction), and no tension (no ropes or cables pulling on the car).

Answer:

Normal, Gravity, Friction, Air Resistance
