Title: The Dynamics of Newton's 3 Laws


1
The Dynamics of Newtons Laws
  • By Ryan Thomas

2
Magnetic Force
  • Magnetic forces are very large in comparison to
    gravitational forces. Magnetic forces are caused
    by moving electrical charges. Magnetic and
    electric forces are very closely related.

3
Electric Force
  • The force that appears when you push on something
    with your hand is an electric force. This
    electric force of repulsion develops as the
    electrons of the hand are brought close to the
    electrons of an object.

4
Gravitational Force
  • Gravitational force is an extremely weak force in
    comparison to the other forces. If two tennis
    balls are held one meter apart, the gravitational
    force between them is only 0.00000000001 newtons.

5
Weak Interaction Nuclear Force
  • Nuclear forces are much stronger than any of the
    other forces. The nuclear force holds the nucleus
    of an atom together in spite of the strong
    electric force of repulsion between its protons.
  • The second force inside a nucleus is the weak
    interaction force. This is the force believed to
    break some atoms apart.

6
Newtons 1st Law of Motion
  • A body continues in its state of rest, or of
    uniform motion in a straight line, unless its
    acted upon by a net eternal force.
  • Example When youre riding in a car and the car
    stops your body lunges forward because it wants
    to continue moving.

7
Newtons 2nd Law of Motion
  • When an unbalanced force acts on a body, the body
    will be accelerating.
  • Example when you hit a golf ball is hit by a
    golf club the ball goes in the direction you hit
    the ball.

8
Newtons 3rd Law of Motion
  • Every force is accompanied by an equal and
    opposite force.
  • Example When you hit a baseball with a baseball
    bat, the ball goes further than the ball because
    you hit the ball with more force than the ball
    had.

9
FMA
  • This means that force equals mass times
    acceleration.
  • Example The force that was exerted on the car is
    found by multiplying the cars mass times the
    acceleration it has.

10
M F/A
  • This means mass equals force divided by
    acceleration.
  • Example The mass of a car is found by dividing
    the force exerted on the by the acceleration of
    the car.

11
A F/M
  • This means that acceleration equals force divided
    by mass.
  • Example The acceleration of a car is found by
    dividing the force exerted on the car by the mass
    of the car.

12
W MG
  • This means that weight equals mass times
    gravitational pull.
  • Example Your weight is found by multiplying your
    mass by your gravitational pull.

13
M W/G
  • Mass is found by dividing your weight by your
    gravitational pull.
  • Example Your mass is found by dividing your
    weight by your gravitational pull.

14
G W/M
  • Gravitational pull equals weight divided by mass.
  • Example Your gravitational pull is found by
    dividing your weight by your mass.
