Ball Rolling On Frictionless Surface
Lastly let s try rolling objects down an incline.
Ball rolling on frictionless surface. The ball will only slide on a friction less surface. Ice is nearly a frictionless. Walking does not work on a frictionless surface because taking a step requires gripping the ground through friction. This often heard question exposes pervasive misconceptions about friction that can arise from inadequate textbook treatments of the subject.
Frictional force between ba. A ball rolling without slipping on a horizontal surface encounters a frictionless downward sloping ramp as shown above. Rolling down an incline. Ice is a very low friction surface so if a stationary ice skater pushes another stationary ice skater they both move in opposite directions.
That means spin on the ball is immaterial. A 50 0 kg ball rolling at 10 0 m s eastward on a frictionless surface collides with a 20 0 kg ball rolling westward at 20 0 m s. An example of this can be seen in the real world. Ice has a much smoother surface than the surface of the ground therefore there is less friction acting on the hockey puck compared to a ball rolling on the ground.
When we throw the ball it will continue to be in motion with the same initial velocity unless external forces act on it newton s first law of motion and these external opposing forces will be 1. A constant translational speed with no angular speed b increasing translational speed with no angular speed. The linear motion of a spinning ball and non spinning ball would be same on a friction less surface. Asked by erika on november 14 2012.
Will a cylinder roll forever. However objects resist rotational accelerations due to their rotational inertia also called moment of inertia more. The ball will slide if it has some linear momentum. What is the momentum after the.
Which of the following correctly describes the motion of the ball on the ramp. If a rigid solid metal sphere or cylinder is rolling without slipping on a perfectly smooth rigid and frictionless horizontal surface would it ever come to a stop.
