What else can I help you with?
Is the resistance of a smooth surface to abrasion or scratching?
Yes, a smooth surface offers less resistance to abrasion or scratching compared to a rough surface. This is because a smooth surface has fewer irregularities or rough areas that can catch or snag against an abrasive material.
Why does a smooth object glide when rubbed over a smooth surface?
Because if there are no rough edges then there is less resistance.
Does a basketball roll faster on a smooth surface or a rough surface?
A basketball will roll faster on a smooth surface due to less friction compared to a rough surface. The rough surface creates more resistance, slowing down the ball's movement.
Is greater force needed to move an object over a smooth surface than over a rough surface?
No, greater force is typically needed to move an object over a rough surface compared to a smooth surface. This is because the irregularities on a rough surface create more friction, making it harder to overcome resistance and move the object. Smooth surfaces offer less resistance to movement.
How does a surface affect friction?
Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
Why does a ball roll faster on a smooth surface than on artificial turf?
A ball rolls faster on a smooth surface because there is less friction between the ball and the surface. On artificial turf, the texture and composition create more resistance, slowing down the ball as it rolls. Smooth surfaces allow the ball to glide more easily, resulting in faster movement.
Is the amount of friction greater between rough surfaces smooth?
smooth surfaces have less friction, take an ice rink for example, the resistance on that is less than the resistance on asphalt
Why do small objects have less air resistance?
Small objects have less air resistance because they have less surface area compared to larger objects. Air resistance is caused by the interaction between the object's surface and air molecules as they flow around it. With less surface area, there are fewer interactions and therefore less air resistance acting on the object.
Is the force is greater on a smooth surface or on a rough surface?
The force is greater on a rough surface compared to a smooth surface, due to the increased friction between the surfaces. The rough surface provides more resistance to motion, requiring more force to overcome the friction.
Does a smooth surface reduce friction?
Yes, a smooth surface reduces friction because there are fewer microscopic irregularities that can create friction between surfaces. This results in less resistance when two objects slide or move against each other.
Is friction is more on smooth surface?
Surface friction is defined as the resistance of an object experiences during motion. So, for the same object, a smooth surface has less friction than a rough surface. Think about skating on ice or a piece of plywood!
Which force will decrease if the surface of the ramp is made smoother?
Friction is the force that will decrease if the surface of the ramp is made smoother. Smooth surfaces reduce friction by allowing objects to slide more easily with less resistance.
