(1) Why use seat belts? Riding in a car you and the car have the same motion. When the brakes are applied, the brakes stop the car. What stops you? Eventually the steering wheel, the dashboard, or the window unless they are replaced by a seat belt, which stops your body. When the accelerator is depressed with the car in gear the motor turns the wheels and the car moves forward. What moves you forward? As the car moves forward the seatback comes forward, contacts, you and pushes you forward.
(2) While you are riding in the front passenger seat of a car, the driver suddenly turns left. What about you? You continue to move in a straight line until the door to your right, turning left, eventually runs into you. In the car it may appear to you that you slid outward and hit the door.
(3)When you slide your book on floor it will stop soon. When you slide it on icy surface, it will travel further and then stop. Galileo believed that when you slide a perfectly smooth object on a frictionless floor the object would travel forever.
(4)when scoring a hockey goal, the hockey puck slides toward the open goal in a straight line because the ice it slides on is nearly frictionless. If you're lucky, the puck won't come into contact with the opposing goalie's stick, which would cause it to change its motion.
(5)If you dropped a piece of popcorn on the floor, it would stay there until something moved it or picked it up. This does not apply to things in a vauum.

(6)balanced or unbalanced FORCE, act on a a car and a crash-test dummy system that they build with wood, wheels and clothespins.
(7)if a baseball is sitting on a table at rest it will stay at rest until acted upon by an unbalanced force. The second example is if someone goes into outer space and throws a baseball as hard as they can, the baseball will not slow down or change direction until it is acted upon by an unbalanced force such as a meteor
(8)if you threw a ball up it would go on forever in the direction you threw it and at the speed you threw it, unless it got hit
(9)if a ball is thrown it will go in the same direction and speed until acted upon by an unbalanced force such as gravity which will bring to the floor. The friction in the floor will then slow it down.
(10)someone is riding their bike and and a big max truck is coming to and to max truck hits the guy on the bike goes flying because the max truck mass is more than the guy on the bike mass.
