• Usain Bolt ran 100 meter in 9.58 sec
Displacement• How far an object has moved in relation to

• Record the time your car travel from 0 to 1 meter (repeat 3 times)
• Repeat the procedure with 0-2 meter and 0-3 meter
• Make sure you do the test twice - with the tires and without the tires
Comic Strip Assignment
• Create a short story using comic strip to illustrate motion or speed
• Must have at least 6 (color) pictures
