Key words: Force, acceleration, mass, inertia, reaction-action, opposite-equal
Newton’s Laws of Motion
An object at rest will remain at rest unless an unbalanced force stops it
An object in motion continues in the same speed and direction as the vehicle
Experiment 1: What we did was first put a big bucket down then put a pretty wide thick book down , last we put an empty paper towel roll and a golf ball on top. Then we took a yardstick and SMACKED it against the book and the book went forward the paper towel roll went backward and the golf ball fell right into the bucket. So now thats proof something at rest will stay at rest.
Experiment 2: What we did is we took a small plastic car and a small troll (stuffed animal) and put it in the car. One person held the yardstick the other pushed the car/troll into the yardstick, the troll went FLYING forward but the car stopped. Now you know to always wear a seat belt. 🙂
Law 2. Acceleration is produced when a force acts on a mass. The greater the mass ( of object being acceleration) the greater the amount of force needed (to acceleration the object).
The greater the mass the more force you have to put into it
Acceleration is produced when a force acts on a mass. The greater the mass ( of object being acceleration) the greater the amount of force needed (to acceleration the object).
Experiment 1: What we did first is we all got a partner and grabbed a chair. First we pushed it to the other side of the room and it was pretty easy, then we had our partner sit in it then push it to the other side of the room and it was pretty hard, because when it was just the chair there was less mass so you didn’t need to use a lot of force, but with a person in the chair they have more mass and you need more force.
For every action there is an equal and opposite reaction.
Experiment 1: What we did first we had was two scooters and two people. we had two people push against each other and one them went straight back and the other went to the trash can.
Experiment 2: First we got string and tied one end of the other side of the room, then we cut a straw and put it through the string then tied the string to both ends of the room. Then we got a black balloon and blew the balloon up (but don’t tie it) then tape the balloon to the straw and let it go! It went about half way but there was an action and a reaction, the air that came out of the balloon was the reaction the balloon going forward was the action. It happens with a lot of things seadoos, walking, swimming, a lot of things
