Is a rolling marble a kinetic or potential energy?
A rolling marble has kinetic energy due to its motion.
What forces make marbles roll?
Marbles roll due to a combination of gravitational force pulling them downward and frictional forces between the marble and the surface it is rolling on. If the surface is smooth, gravity will dominate and the marble will roll faster. If the surface is rough, friction may slow down the marble's rolling.
What is the coefficient of friction for marble?
The coefficient of friction is not defined for a single substance, but for two substances that have contact with each other - for example, marble with marble, marble with wood, etc.; it may also vary a lot depending on lubrication. That is, on a wet wet marble floor you'll slip easier - there is less friction - than on a dry one.
How can marbles reduce friction?
Marbles can reduce friction because their smooth, rounded surface allows them to roll more easily than flat surfaces. This rolling motion helps to minimize the contact area between the marble and the surface it is rolling on, resulting in less friction and smoother movement. Additionally, the hard surface of marbles reduces deformation when in contact with surfaces, further reducing friction.
What kind of energy is there when a marble rolls across a flat floor?
The marble has kinetic energy as it is moving. Additionally, there may be some small amount of potential energy due to the height of the marble above the floor.
Does friction cause the average speed of a marble on a floor to decrease?
Yes, because of rolling friction which is a type of friction that any rolling object experiences. This friction adds resistance to roll which will slow the marble and eventually stop.
What are somethings with little friction?
Ice and marble floor have little friction and results in objects slidding as they go across the surface.
What force slows a marble rolling flat on a surface?
The force that slows a marble rolling on a flat surface is friction. Because friction is what stops something when it's moving. Like when you throw a ball, it starts going slower, and slower, and slower, until it stops. Why? Well you know a force is involved in something like this! But what kind? It's called: Friction!
What causes a marble to roll?
Because of the force of friction pushing against the ball. The only way it could avoid that is if it wasn't rubbing against the ground and was instead closing floating in air, like the puck in air hockey. The air blowing up on it keeps the puck and the table from rubbing against each other and causing friction. :)
How could you use a board and different materials found in a classroom to show the effect of friction on a rolling marble?
Every time the marble hits something then it will slow down and eventually stop.

What are all the forces acting on marble rolling up a hill?
When a marble rolls up a hill, the primary forces acting on it are gravity, normal force, and friction. Gravity pulls the marble downward, acting against its upward motion, while the normal force acts perpendicular to the surface of the hill, supporting the marble. Friction occurs between the marble and the hill's surface, opposing the marble's motion and helping to stabilize it. As the marble ascends, these forces determine its acceleration and eventual stopping point.

What do you think causes the marbles to stop rolling?
If you were to roll a marble (across what doesn't matter), what slows the object down is called traction.
Is it possible for a marble to go 10 ft per sec?
Yes, it is possible for a marble to travel at 10 ft per second or even faster depending on the force applied to it and the surface it is rolling on. The speed of the marble will be influenced by factors such as its size, weight, and friction.
