Final answer:
Non-linear acceleration is caused by tension, friction, and the force of gravity.
Step-by-step explanation:
Non-linear acceleration can be caused by a combination of three forces: tension, friction, and the force of gravity. Let's take a look at each force:
- Tension: In scenarios involving a rope or string, tension can cause non-linear acceleration. For example, when a tether ball is being hit, the tension in the rope causes the ball to move in a curved path.
- Friction: The force of friction can also result in non-linear acceleration. For instance, a car going around a curve experiences friction between the tires and the road, which allows it to change direction.
- Force of Gravity: Gravity can cause non-linear acceleration when an object is in freefall or when a satellite orbits a planet. In these cases, the force of gravity acts as a centripetal force, pulling the object toward the center of its circular path.
