investigating motion Flashcards
What are examples of objects that could be used in the experiment?
A paper cone and a tennis ball.
What is the independent variable in the experiment?
Distance, d.
What is the dependent variable in the experiment?
Time, t.
What is a control variable in the experiment?
Use the same object (paper cone, tennis ball, etc.) for each measurement.
What height should be measured for the experiment?
Measure out a height of 1.0 m using the tape measure or metre ruler.
What should be done with the object during the experiment?
Drop the object (paper cone or tennis ball) from the measured height.
How should the time be measured in the experiment?
Use the stop clock to measure how long the object takes to travel the distance.
What should be recorded during the experiment?
Record the distance travelled and time taken.
How many times should steps 2-3 be repeated?
Repeat steps 2-3 three times, calculating an average time taken for the object to fall a certain distance.
What heights should be tested in the experiment?
Repeat steps 1-4 for heights of 1.2 m, 1.4 m, 1.6 m, and 1.8 m.
