How will the player stop sliding?
Friction opposes the motion of two objects when they come in contact with each other. In this case friction between the players’ shoes and the basketball court keep the players from sliding.
What material causes the most friction?
Rougher surfaces have more friction between them than smoother surfaces. That’s why we put sand on icy sidewalks and roads. You can’t slide as far across ice with shoes as you can on the blades of skates (see Figure below). The rougher surface of the soles of the shoes causes more friction and slows you down.
What material has least friction?
Glass
What is a good experiment for friction?
Another simple experiment illustrating the friction is inserting a pencil into a bottle. Bottle should be light and filled with rice. Put a pencil into a bottle and try to pull out the pencil. The bottle will pick up also.
What are two ways friction can be increased?
There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction between the tyre and the road.
Can we reduce friction to zero?
Friction can be reduced to a great extent by polishing surfaces or by using a large amount of lubricants such as oil, water, or grease but we cannot reduce friction to zero.
How does speed affect friction?
Friction drag force causes objects to slow down as they move through a fluid, such as air or water. As an object’s speed increases, the drag force from the fluid increases exponentially. • For example, when you drive at high speeds, the frictional force of air on the car increases, and fuel economy decreases.
Does friction increase as acceleration increases?
Frictional Force is the force exerted by a surface as an object moves across it or makes an effort to move across it. So frictional force will be affected by the change in speed. The higher the acceleration, the higher the frictional force experienced by the object.
Does friction force depend on the speed?
Friction is a contact force when two surfaces interact. Notice that both of these friction formulas ONLY depend on the coefficient of friction and the normal force. It does not depend the area of contact, it doesn’t depend on the sliding speed.
