What are the effects of acceleration and gravity on a moving body? Find out with our easy, low-cost lab which has a brand-new experiment! Determine acceleration, speed and distances attained when applying a variable force. Propel a steel ball or two down an aluminum track with a spring-activated plunger so that you hit one or more balls positioned further down the track. Observe how far and how many balls move. Vary the force applied by using any of the four trigger positions.
