The Dynamics of Newton's 3 Laws

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.
