-Air track will be leveled. Turn on the air supply under the air track bench.
-Push cart and allow it to bounce back and forth along the 2.5 meter track.
-Nearly all energy loss (up to 10%) occurs during the collisions at the ends of the track.
-Leave some slack in the table cloth so your hands will come up to speed before the cloth becomes taut.
-Vary the acceleration of the block by changing the mass on the hanger.
-Suspend a partly extended slinky in the air
-Release the slinky.
-Measure static friction by noting the scale reading just before the block slides.
-Pull block along lecture bench at a constant speed to measure sliding friction.
