Safety Precautions: Be careful when testing the free fall speed.

Purpose: The accelerations will stay constant, while the velocities will increase.

Materials and Equipment: Wood Cart, Tape, The Spark Machine, Tractor, Special Tape for Sparks, Plank

1) Determine 5 meters on the ground and for each meter place a piece of tape down.

2) Switch the tractor so that it rolls forwards. Each time that the tractor crosses the tape, observe the time and write it down.

4) After you have finished all the trials calculate the interval velocity and interval acceleration for each trial.

1) Take the cart and tape the special spark tape to the back. Then thread the tape through the spark machine.
