Title: The Dynamics of Newton's Laws


1
The Dynamics of Newtons Laws
  • The study of Forces Which Cause Motion.
  • By Benjamin N. Rose

2
Magnetic Force
  • Large compared to gravitational forces.
  • Produced by electric charges.
  • Closely related to electric forces.

3
Electric Force
  • Electric force is also stronger compared to
    gravitational forces.
  • An example is pushing a chair.

4
Gravitational Force
  • The weakest force
  • If two tennis balls are held one meter apart, the
    gravitational force between them is 0.00000000001
    newtons.

5
Weak Interaction/Nuclear Force
  • The two strongest forces.
  • Both forces act in the nuclei of atoms.
  • The nuclear force is what holds an atom apart.
  • The weak interaction force is what tries to split
    them apart.
  • They are also the hardest forces to
    observe-especially weak interaction.

6
Newtons First Law
  • This law is also known as the law of inertia.
  • The law states that a body at rest, stays at
    rest, and that a body in motion stays in motion,
    unless acted upon by another force.
  • An example of this is say a ball sits in space is
    being acted upon by no force. It is at rest. But,
    a force has acted on it now it is in motion and
    unless it is stopped by another force it will go
    on forever.

7
Newtons Second Law
  • This law states that when a unbalanced force acts
    on a body, the body will be accelerated.
  • An example of this is when one force is having a
    stronger effect on an object than another like a
    rocket blasting off into space. The rockets
    electric force is stronger than earths
    gravitational force.

8
Newtons Third Law
  • This law is also known as the law of action and
    reaction.
  • The law states that a single force can never
    exist. Every force is accompanied by an equal and
    opposite force.
  • An example is the Earth and the Moon. Even though
    the Earth has more mass, the moon is still coming
    at it with an equal amount of force.

9
FMxA
  • This equation represents force equals mass times
    acceleration.
  • An example of this is if you add mass to an
    object versus another object of smaller size.
    This would cause the smaller object to have more
    acceleration.

10
MF/A
  • It is just another example of FMxA.

11
AF/M
  • Also just another example of FMxA.

12
WMxG
  • This means weight equals mass times the
  • Acceleration of gravity.
  • If an object was 10g on earth it would weigh 98
    newtons.

13
MW/G
  • This formula finds the magnitude of force.
  • Same result as wmxg.

14
GW/M
  • Also for finding magnitude of force.
  • Same result as wmxg.
