Animation marble down a ramp.
Marble 1 10g marble 2 20g marble 3 25g marble 4 40g marble 5 30g.
In this experiment the inclined plane makes work easier by allowing gravity without any help from you to move the marble down the ramp.
The fact that f gravity mg is important because it says that the acceleration of a falling body doesn t depend on its mass.
Potential energy is the energy that is stored in an object.
An example of potential energy is a stretched out rubber band the farther you stretch it the more potential energy it has.
Rotational kinetic energy 4 of 19 ball hollow rolling down an incline duration.
The time it took for the marble to go through the photogate timers was 3 00 seconds.
The height of the ramp is now 30 inches.

This animation depicts a classic physics demonstration of balls rolling different ramps.
Acceleration is a vector meaning it has a direction and a magnitude so this equation really boils down to g an acceleration straight down toward the center of the earth.
