Final answer:
Examples of everyday circular motion where different types of forces cause centripetal acceleration include: the Earth's gravity acting on the Moon, the normal force on a roller coaster car, static friction between car tires and the road, and tension in the rope of a tetherball.
Step-by-step explanation:
When examining everyday examples of circular motion, there are various forces that can provide the necessary centripetal acceleration. Here are examples for each of the forces asked about:
- Gravity: An everyday example of circular motion where gravity provides the centripetal force is the orbit of the Moon around the Earth. The gravitational pull of Earth ensures the Moon's stable orbit, acting as the centripetal force that keeps the Moon moving along its circular path.
- Normal Force: The normal force acts as the centripetal force in the case of a roller coaster car at the top of a loop. The track pushes on the car with a force that is perpendicular to the car's surface, which keeps the car following a circular trajectory.
- Static Friction: When a car turns around a curve on a road, static friction between the tires and the road provides the centripetal force necessary for circular motion. Without this force, the car would not be able to turn and would continue moving in a straight line.
- Tension: A classic example of tension providing the centripetal force is a child playing with a tetherball. As the ball swings around the pole, the tension in the rope keeps the ball moving in a circle.
