2.Tape two metre sticks together along their edges to
make a V-shaped channel. Set up one end of the
metre sticks on a book so that they act a ramp.
3. Predict how much time it would take the ball to roll
50 cm. Record your prediction in your data table.
4. Release the steel ball from 0 cm so that it rolls down
the ramp. Using a stopwatch, measure the time it
takes to roll 50 cm. Record the time in your data
table. Repeat twice more, and average your result of
the three trials.
5. Write a sentence describing the motion of the ball.
6. Predict how much time it would take the ball to roll
100 cm. Record your prediction.
7. Release the steel ball from 0 cm so that it rolls down
the ramp. Using a stopwatch, measure the time it
takes to roll 100 cm. Record the time in your data
table. Repeat twice more, and average your results of
the three trials.
8. Determine the time it takes the ball to travel from
50 cm to 100 cm by subtracting your average time
in step 4 from your average time in step 7. Record
this time.
9. Clean up and put away the equipment you have used.
