Five marbles roll down a ramp.
Use 1 d kinematics to predict the velocity of the ball xi at the bottom of the ramp.
Sample learning goals explain the motion of an object on an incline plane by drawing free body diagrams.
The fact that f gravity mg is important because it says that the acceleration of a falling body doesn t depend on its mass.
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.
In this experiment the inclined plane makes work easier by allowing gravity without any help from you to move the marble down the ramp.
