A Ball Rolling : What forces are involved?

AI Thread Summary
In the discussion about a basketball rolling on a level road, key forces at play include gravity, friction, wind resistance, and rolling resistance. Gravity acts downward, while friction and rolling resistance oppose the motion, with rolling resistance specifically related to the deformation of the ball. Wind resistance is also considered, but it is not an example of inertia. The normal force from the ground does not work against the rolling motion. Understanding these forces is essential for analyzing the dynamics of rolling objects.

Let's say that a basketball was rolling on a road. A completely level road. A road that wasn't downhill or uphill, just straight. So, as its rolling, what forces are working against it? I'm thinking of 3. Gravity and friction. Also wind resistance. Am I correct? Would the wind resistance be an example of inertia?

Also rolling resistance, which is energy dissipated by deformation of the ball.
 
you must also account for normal force that exerts from the ground on the ball
 
The normal force is not working against the rolling.

I think it is natural to decompose this into two parts:

1) Energy dissipated because of the overall shape deformation of the ball.

2) Energy used to brake the microscopic contact bond between the ball and the ground.

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
