1st Law of motion

• “the law of inertia”-  An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Examples:

  • A person sky diving — when the parachute opens it slows the fall.

  • A marble rolling on a floor– it will slow down because of Friction

2nd Law of motion

f=ma

• Acceleration is produced when a force acts on a mass the greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerated the object).

• Example:

  • A fully loaded truck will have a harder time to stop than a not fully truck.

  • A person on a chair is harder to push then a person not on a chair

3rd law of motion

Force-Pairs

• For every action there is an equal and opposite reaction.

• Example: if you shot a gun the Bullet would go one way and the gun would go the other way which is called a kick.

• If someone was on a scooter and tried to push a cart the person on a scooter would go backwards and the cart would go forwards which is called an equal and opposite reaction

2. How should we apply that to our  pinball machine?

Law #1-For law number 1 the ball will stay in motion until the game is over and then when the ball goes into the launcher and it will stay at rest until someone  launches the ball to start the game.
