Inclined Planes Marble Roll Lab

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. Copy the data from the first set of measurements in hypothesis a into the data table for hypothesis b unless you prefer to collect that data a second time. Roll the marble down the longer ramp for increasing amounts of time one second two seconds three seconds etc until the time the marble goes past the end of the ramp.

Generally having a greater mass means that a rolling object such as a ball will have a greater moment of inertia.

Inclined planes marble roll lab.

Kinetic energy is the energy of an object in motion. Call out the numbers as marbles roll into the cups. Another example is a marble teetering at the top of an inclined plane. Steel ball bearing or marble wood block stopwatch tape meter stick protractor procedure.

Video of a steel ball rolling down an incline plane with uniform acceleration. For many years the effects of mass on objects rolling down an inclined plane have been studied and well known. My two hypotheses suggested that the surface texture of an inclined ramp would affect the distance traveled by a marble rolled down it and that the less textured the ramp s surface was the farther the marble would roll. Using a water clock galileo measured the time it took for the ball to roll a known distance down the inclined plane.

Raise the top of the ramp to 0 15 m. Drop a marble or other small ball at the top of the inclined plane and watch it roll down to land in one of the cups. Average calculated on rolls 2 3 and spare roll. Aim for a certain number.

When the rubber band is released and pours out all that energy it had stored up or when the marble begins to fly down the inclined plane that energy is kinetic energy. Divide the ramp s length into six equal parts and mark the six positions on the board with pieces of tape. Add numbers or letters to the tops of the cups or to the tape at the front of the cups. Experiment with different sizes of marbles.

The ball is released from different distances up the incline and the time is m. After many trials he observed that the amount of time it took for the ball to roll down the entire length of the ramp was equal to double the amount of time it took for the same ball to only roll a quarter of the distance. Starting with the cylinder at rest use the stopwatch to measure the time to roll 1 0 meter down the ramp. These positions will be your.

Time to roll 1 0 m when h 0 1 m 3. Set up a ramp with the angle of the incline at about 10 to the horizontal as shown in figure a.
