Class Notes: Newton’s Third Law - action and reaction

Newton’s Third Law

  1. When one object exterts a force on a second object, the second object exerts and equal force on the first object in the opposite direction.

    • for every action there is an equal but opposite reaction.

    • action - the initial force

    • reaction - the equal but opposite push back

    • act on different objects (sketch)

  2. because action and reaction act on different objects - they sometimes behave very differently.

    • Examples:

      • ball bounce

      • standing on floor

  3. action and reaction make a force pair.

    • Forces always occur in pairs.

    • normal force is a reaction force to pushing against a surface

Todays Agenda:

Finish Newton’s second Law of motion notes:

  1. The acceleration of an object is equal to the Net force acting on it divided by its mass

    • A = Fnet/M.

    • If mass increases, acceleration becomes less

    • If mass decreases, acceleration becomes more

  2. Example problem in slide show.

  3. Example Problem(s)

    • What is the acceleration of a skateboarder with a mass of 50 kg who us pushing with a net force of 100 N?

    • What is the acceleration of a 100 kg skydiver who has a net force of gravity pulling him downward with a net force of 980 N?

Class Notes:

Newton’s 1st Law

  1. If the net force acting on an object is zero, motion does not change.

    • does not mean there is no motion - just no CHANGE in motion

    • stopped or constant velocity

  2. Also called Law of Inertia

    • inertia is the tendency of an object to resist motion in proportion to its mass

    • objects do not change motion unless an unbalanced force acts upon them.

  3. Balanced forces - net force = 0

    • object at rest

    • object maintains constant speed and direction (velocity)

  4. Unbalanced froces (Net force >0)

    • object speeds up

    • object slows down

    • object turns

Newton’s second Law of motion

  1. The acceleration of an object is equal to the Net force acting on it divided by its mass

    • A = Fnet/M. also F = M x A

    • If mass increases, acceleration becomes less

    • If mass decreases, acceleration becomes more

Today’s Lesson:

Combining Forces

  1. Net Force is the combination of all forces acting upon a body.

    • When forces act together in the same direction, they are added.

    • When forces act in opposite direction, the are subtracted.

  2. Vectors are used as a way to identify the direction and magnitude (strength) of the net force.

    • example

      • use vectors to determine the net force on a car with an applied force of 1500 N acting to the right moving it forward and a friction force of 2000 N acting to the left.

  3. Also, assign forces a sign (+/-) based on their direction (just like a coordinate system)

    • +for right and up

    • - for left and down

    • Example

      • use vectors to determine the net force on a model rocket with an applied force of 1000 N acting upward and a friction force of 250 N acting downward.
