Suppose you start the marble at rest xe 0 m s and it travels a distance of d.
Animation marble down a ramp.
An example of potential energy is a stretched out rubber band the farther you stretch it the more potential energy it has.
The table lists the mass of each marble.
F gravity ma mg.
Marble 1 10g marble 2 20g marble 3 25g marble 4 40g marble 5 30g.
Explore forces energy and work as you push household objects up and down a ramp.
Use 1 d kinematics to predict the velocity of the ball xi at the bottom of the ramp.
This animation depicts a classic physics demonstration of balls rolling different ramps.

Each marble reaches the bottom of the ramp at a speed of 3 meters second.
In this experiment the inclined plane makes work easier by allowing gravity without any help from you to move the marble down the ramp.
Potential energy is the energy that is stored in an object.
The motion sensor gave me the speed of the marble at each different height.
Graphs show forces energy and work.
Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet.
Which marble has the highest kinetic energy at the bottom of the ramp.
As you can see there is a direct relationship between the height of the ramp and the time it took the marble to go down the wooden ramp.
Five marbles roll down a ramp.
The best gifs are on giphy.
The time it took for the marble to go through the photogate timers was 3 00 seconds.
Sample learning goals explain the motion of an object on an incline plane by drawing free body diagrams.
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.
G 9 8 meters second 2 32 2 feet second 2.
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.
Which ball wins the ramp depends on the details of the ramps shape.
The height of the ramp is now 30 inches.
The fact that f gravity mg is important because it says that the acceleration of a falling body doesn t depend on its mass.
In one of your experiments you will roll a marble down a ramp to provide an initial horizontal velocity.
Mark the distance.
