How does friction affect the type of rolling motion of an object. For instance, does having more friction than the required friction for rolling cause the object to spin?
I think you misunderstood me. A typical example is a ball rolling down an igloo from the top. The friction changes as it goes along the surface. So, when the ball starts sliding, is the friction less than or greater than required friction for rolling?jerromyjon said:Friction is the resistance to motion. Force is required to overcome resistance then acceleration occurs and friction increases.
Friction is a force that opposes motion between two surfaces in contact. It can affect rolling motion by creating a resistance force that slows down or stops the rolling object.
The type of surface can greatly affect friction and rolling motion. Rough surfaces typically have higher friction, which can slow down rolling motion. Smooth surfaces, on the other hand, have lower friction and can allow for easier rolling motion.
Some real-life examples of friction and rolling motion include a car's wheels rolling on a road, a ball rolling on a grassy field, or a skateboard rolling on a sidewalk. In each of these examples, friction is present and affects the rolling motion of the object.
Friction can decrease the speed of rolling motion by creating a resistance force. This force acts in the opposite direction of the rolling motion and can slow it down. However, in some cases, friction can also be used to increase the speed of rolling motion, such as in the case of a bowling ball rolling down a lane.
No, friction cannot be completely eliminated in rolling motion. It is a natural force that is always present when two surfaces come into contact. However, friction can be reduced by using smoother surfaces or by adding a lubricant, such as oil, between the surfaces.
