Third Law of motion | "For every action, there is an equal and opposite reaction." |
First Law of motion | "An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force." |
14. Blood rushes from your head to your feet when the decending elevator you are riding on quickly stops. | First Law of motion |
15. To dislodge ketchup from the bottom of a ketchup bottle, it is turned upside down and thrust downward and abruptly stopped. | First Law of motion |
16. Headrests are placed in cars to prevent whiplash injuries during rear-end collisions. | First Law of motion |
17. While riding a skateboard you hit a rock which abruptly halts the motion of the skateboard. You fly forward off the board. | First Law of motion |
18. You are riding in a car at a high rate of speed and the driver makes a sharp turn. Your body lurches in the original path of motion and you get pushed into the side of the car. | First Law of motion |
