In what surfaces does the ball roll faster Why?
It is because the rough surface is having more friction that the smooth surface. A ball, rolls faster in a smooth surface because it is having less or no friction at all to stop it.
Does surface affect speed?
The makeup of the two surfaces in contact has a great affect on the amount of friction. So, the short answer to your question is yes, if you change the surface that the ball rolls down, the ball’s speed will change.
What is the effect of different surfaces on the movement of a rolling object?
Rolling friction is affected by the texture of both the surface and the rolling object. Had I used a tennis ball it probably would have rolled a shorter distance because of the ball’s texture. Rolling friction is also affected by how large the contact area is between the object and the surface.
How does different surfaces affect friction?
A: Heavier objects press together with greater force, and this causes greater friction between them . Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them . Heavier objects also have more friction because they press together with greater force.
How does the surface affect the speed of a toy car?
The general idea is that rough surfaces create more friction with the car’s wheels, while there is little friction between a car and a smooth surface, causing the car to travel faster and make it harder to stop immediately.
What is the velocity of the ball?
Conclusion: The magnitude of the velocity of the ball is 26.3 m/s for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward. Notice the figure above has the positive y direction upward.
What surface do you run fastest on?
Pros: As all road-runners know, asphalt is one of the fastest surfaces you can find, it’s easy to measure distances on it, and it’s simple to keep up a steady rhythm. While it’s rather solid, it’s a predictable, even surface that puts less strain on the Achilles tendon than softer or uneven terrains.
Do different surfaces affect the speed of cars?
Will a ball roll faster on a wood or tile surface?
The ball will roll at a faster rate over the timber floor, than the tiles and carpet, as it is smoother.
Does speed affect friction?
sliding or kinetic friction between 2 surfaces that are moving relative to each other does not change with speed, but skin friction and drag is dependent on the speed, which you and others have noted: the faster the speed, the greater the ‘drag’.
