● How does an object change motion?
An object can change motion in several ways, including:
1. Applying a force: When a force is applied to an object, it can cause the object to accelerate or decelerate, changing its motion.
2. Changing the direction of force: If a force is applied in a different direction than the object is currently moving, it can cause the object to change direction.
3. Changing the mass of the object: Increasing or decreasing the mass of an object can affect its motion. A heavier object may be more difficult to accelerate or decelerate, while a lighter object may change motion more easily.
4. Changing the surface or environment: The surface on which an object is moving can also impact its motion. For example, a rough surface may provide more friction, slowing down the object, while a slippery surface may allow the object to move more easily.
5. Exerting external forces: External forces such as gravity, air resistance, or friction can also affect the motion of an object, causing it to speed up, slow down, or change direction.
