Skate Force - Using a Skateboard to Investigate Force, Mass and Acceleration
This lesson investigates Newton's First and Second Laws of Motion by observation and interpretation of graphs. It includes a stop motion motion video and graphs based on measurements of a skateboard propelled by an electric leaf blower with different sized forces and masses. It allows students to investigate the effects of forces produced by touch, magnetism and gravity. It introduces the concepts that acceleration increases with force and decreases with mass.
