The Dynamics of Newton's Laws

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.
