A ruler and three books are used to make a ramp. Marble X is placed at the top of a ruler, and marble Y is placed in front of the ruler on the ground, as shown.
When marble X rolls down the ruler and hits marble Y, marble Y rolls away from the ruler. The activity is repeated except with only one book supporting the ruler.
What will happen when marble X and marble Y collide after the number of books under the ruler is decreased?
The distance marble Y moves will increase because the energy from marble X will decrease.
Marble Y will move farther because more energy is transferred from marble X.
The distance marble Y moves will not change because energy from marble X will not change.
Marble Y will not move as far because less energy is transferred from marble X.
