Demonstrate the difference between constant and changing acceleration
The High Low Road demo allows students to see that the shortest distance between two points is not necessarily the fastest while providing an excellent dramatization of potential and kinetic energy and friction. Two steel balls are released simultaneously – one on a straight metal track, the other on a bent metal track. Have students hypothesize which ball will be the winner. The outcome is sure to surprise. Includes: 2 -1” steel balls, large support block, small support block, straight metal track, bent metal track.
