How do different surfaces affect the momentum of marbles?

How do different surfaces affect the momentum of marbles?

If friction is not a factor, momentum will pass from one object to a second and then to a third at a constant rate. The total amount of momentum transferred would remain constant from the first object to the last.

What is the effect of marble size on rolling distance?

Potential and kinetic energy were not variables in this experiment because the ramp’s height and length did not change and neither did the marble’s shape, size or texture. Conclusion: The marble rolled farther on smoother textures, with texture clearly affecting the distance traveled.

How does friction affect a marbles motion?

Friction: Here’s a simple way to explain friction to a child: “If you rolled the marble down a grassy hill, it would move more slowly than down a smooth sidewalk. Friction is the force that slows objects down.” While constructing your marble run, hypothesize about the different materials that will line the tubes.

What affects the motion of the marble?

-Objects move when pushed or pulled. -Objects will change speed and direction when in contact with another object. -Force (how hard the marble is pushed) will affect how fast the marble moves (speed).

How does the speed of a marble change as it rolls down a ramp What causes this change in speed?

The surface of the ramp can cause friction on the ball; therefore kinetic energy is lost, so the ball slows down. Different surfaces of ramp will change the speed of the ball and therefore also the distance it rolls. The weight of the Marble will affect the distance it roll and also the speed at which it rolls at.

How does speed of a marble change as it rolls down a ramp What causes this change in speed?

As the marble rolls down the hill its potential energy is converted to kinetic energy (its height decreases, but its velocity increases). When the marble goes back up the loop its height increases again and its velocity decreases, changing kinetic energy into potential energy.

What causes the marble to speed up?

Continuously blowing on the marble causes a greater change in velocity—it moves faster when you blow in the direction it is moving and slower when you blow against the direction in which it is moving.

What causes the marble to speed up and slow down?

Friction occurs any time two objects rub against each other. This rubbing slows movement and creates heat in the process. You can feel this heat by quickly rubbing your hands together. If the force of friction is greater than the force of gravity, the marble will roll to a stop.

Why does marble go faster on a curved path?

The marble on the curved path is pulling a Duncan. It drops down and speeds up in the beginning of the path, which means it takes a longer but faster overall path than the straight line of the flatter path. That marble wins the race by optimizing for the shortest time, not for the shortest path.

What causes a marble ramp to slow down?

In my experiment this force was the friction caused by the texture of the ramp. This caused the marble to slow down when the more textured surfaces created more friction. This type of friction is called rolling friction.

What happens when marble is shaped into a cylinder?

If my marble was shaped into a cylinder there would be more contact area between the surfaces and so there would be more rolling friction. Potential and kinetic energy were not variables in this experiment because the ramp’s height and length did not change and neither did the marble’s shape, size or texture.

What makes a sphere roll at the same speed?

Applying the same concept shows two cans of different diameters should roll down the ramp at the same speed, as long as they are both either empty or full. The same principles apply to spheres as well—a solid sphere, such as a marble, should roll faster than a hollow sphere, such as an air-filled ball, regardless of their respective diameters.
