Imagine you are rolling a marble down a wooden ramp for an experiment. What are some variables you can experiment with to increase the velocity of the marble? *

Explanation:

In free fall, gravity constantly accelerates an object (increases its velocity)—until it hits terminal velocity. Specifically, gravity increases a falling object's velocity by 9.8 meters per second (m/s) with every passing second. (Whereas velocity is measured in m/s, acceleration is measured in meters per second squared, or m/s2.) How does this constant acceleration affect the distance that an object travels over time? In this experiment you will roll a marble down a ramp to find out.

A few variables you could change to affect the velocity of this marble are:

1. Change the slant of the wooden ramp.

2. Change the height of the wooden ramp, so gravity has a different effect.

3. Possibly blow the marble?
