Verified Answer :

Final answer:

Several types of forces can change an object's motion, including friction (static, sliding, and rolling) and air resistance. These forces are influenced by factors such as surface texture and the weight of the object. Understanding these forces can help describe how and why objects move differently in various situations.


Explanation:

Understanding Forces that Change Motion

In physics, various types of forces can change an object's motion. The main categories are:

  1. Friction
    • Static friction: This occurs when an object is at rest, and a force is applied but does not cause motion.
    • Sliding friction: This occurs when two surfaces slide against each other, slowing down an object in motion.
    • Rolling friction: This involves the resistance encountered by an object rolling over a surface, such as a wheel on the ground.
  2. Air Resistance: This force acts on objects as they move through air, typically opposing the force of gravity and affecting the motion of objects in free fall.

These forces depend on several factors such as the surface texture, the weight of the object, and the speed at which it moves. For example, a heavy box will have greater static friction compared to a light box when pushed across the same surface.
