rotational dynamics - Why does a ball roll? - Physics ...

The ball rolls because: the friction present between the surface pushes the atoms/particles in contact with surface or ground backwards, hence with centre of mass moving in a direction, the ball's bottom surface (ie. The surface in contact) moves in opposite direction or backwards, causing the ball to roll. The ball slips because there is no ...

Factors Affecting Green Speed

Mowing Height. Ball roll increases when the mowing height is reduced (Fig. 1). Lower mowing heights tend to promote smoother, more uniform surfaces; however, reducing the mowing height below the optimum height for a species or variety can result in a loss of shoot density, root growth and production, decreased carbohydrate synthesis, and increased susceptibility to environmental and …

Big Idea: A push or a pull is a force that makes things move

ball moves. Listen for words that describe the ball's motion (fast, slow, straight, bouncy, etc.). Help students begin to notice a pattern in how the ball moves (The ball rolls in a straight line. More force, or a harder push, makes the ball roll faster and farther.) Example: students roll ball to targets at varying distances (short, medium, long).

How to stop a rolling ball "realistically"? : Unity3D

In the real world things roll to a stop because of friction, air resistance, and deformation, so in this context "realistically" means: The ball slows gradually relative to the rolling resistance coefficient or friction coefficient of the surface. A higher value should slow the ball faster. The ball does not stop if the angle of the surface is ...

(a-c) The type of motion depends on where the cue hits the ball. (a) If the cue hits the ball at exactly (frac{7}{5} R) above the table, the ball will exhibit pure rolling motion, (omega = vR). (b) If the cue hits the ball above the critical spot, it will rotate faster than translate (omega gt vR) and exhibit a slipping rotation.

$begingroup$ In regard to Chris2807's answer, I have a question: If a ball is rolling down the hill on its own, there is a continual component of gravitational force that pulls it down the incline. Since this force produces no torque about the center of mass, I have concluded that a frictional force must be exerted on the contact point at all times when the ball slides down the incline, or ...

The reason a ball rolls farther on dirt is because the grass has more potenial than dirt because once you roll the ball really hard the ball will slow down on grass and the grass is sometimes standing up and the dirt doesn't have any thing to stop the ball the dirt is is flat unlike the grass.
