Marbles On A Ramp.

I learned that the bigger the marble the faster the marble goes. Also more mass = More speed.

I could apply this by: The ramp is sort of like the pinball machine. I also could put sandpaper or something to make more friction.

Newton’s Laws of motion.

• Law #1 – Law of inertia.

  • An object will stay at rest until acted on by an unbalanced force.

    • I learned that if you are in a car and you turn fast your body wants to go straight.

    • I learned that if you are in a car and you hit an unbalanced force and you don’t have a seat belt you will still go forward.

• Law #2 – F = ma (Force = Mass x Acceleration)

  • The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

    • We pushed a medicine ball and a basketball. The medicine ball is heavier than the b-ball, so the medicine ball will go faster and further.

    • We pushed each other in chairs, to see who was heavier.

• Law #3 – Force-Pairs

  • For every action there is an equal opposite reaction.

    • I learned that if you shot 20 gauge the gun would kick some.

    • I learned that if you taped a balloon to a straw on the string and blew it up with air and let it go it would go forward.

I could apply this to my pinball machine by:

The flippers will hit the ball and the flippers will go back
