Newton’s Laws of Motion

Law 1.

• 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.

Law 3.

• 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

Marbles on the Ramp
by Nathan Ribbens
What did I learn from the experiment?
The more weight the marble has the more speed it goes. If the marble goes down the with oil there is less friction. The force of the marble going down is gravity because on earth there is gravity but in space there is no gravity. The acceleration of the speed of the marbles the small one took 2.14 sec to get down the ramp, the medium marble took 2.12 sec to get down the ramp, and the large marble took 2.08 sec to get down the ramp.

How does what I learned apply to a pinball machine?

When the force makes the ball go up and then the gravity pulls the ball down and the steel marble is a conductor.  Like when it goes threw something it could turn on a light bulb.   Marble 1 can go the fastest because the more the weight the more speed and distance.

     This is a pitcher of a Marble on a Ramp.

This connects to when me and my mom went tubing and we went faster and farther than Josh. This shows that the more mass the faster it goes.
