The Dynamics of Newtons Laws

• By Trey McCarty

Dynamics

• Dynamics is the study of forces which cause
  motion.
• Dynamics deals with the cause of motion (forces)
  rather than motion itself.

3
Gravitational Force

• The first one I would like to talk about is
  gravitational. Gravitational is the smallest most
  observable interaction you can see. Say we had
  two tennis balls that where held only one meter
  apart the gravitational force between the is
  0.00000000001 Newtons.

4
Electric Force

• Electric force on the other hand, unlike
  gravitational force, can be very large. Say we
  added an extra atom to the two tennis balls, in
  result of it the electronic force between them
  would be 500000000000000000000 newtons.

5
Magnetic Force

• Magnetic force is very closely related to
  electric force. They are both very large in
  comparison to gravitational forces. Actually,
  magnetic forces are produced by moving electric
  charges. This relationship isnt actually
  completely understood.

6
Nuclear and Weak Reactions

• Despite being very tiny the nuclear forces are
  much stronger than any other forces. The nuclear
  force holds the nucleus of an atom together.
  Today, nuclear power plants use this energy to
  provide electricity for some cities.
• Scientists also believe that a second force
  exists with in the nucleus. This is called weak
  interaction force. It is actually believed to be
  the cause of some atoms breaking apart.

7
Newtons First Law

• Newtons first law states that an object in
  motion tends to stay in motion and an object at
  rest tends to stay at rest unless acted upon by
  an outside force. An example of this would be if
  a soccer ball was kicked it would keep going
  unless you stopped it.

8
Newtons Second Law

• Newtons second law states that the acceleration
  of an object produced by a total applied force is
  directly related to the magnitude of the force .
  An example of this would be if you where pulling
  a box you would get more acceleration on it if
  the box was smaller rather than larger.

9
Newtons Third Law

• Newtons third law states that for every action
  there is an equal and opposite reaction. An
  example of this would be if you where sitting in
  a chair, you would be giving off a downward force
  and the chair would be giving off an opposing
  force.

10
FMA

• FMA is how Newtons second law of motion is
  most often written. An example of this would be
  like if you wanted to hit a baseball you would
  either have to increase your bat speed or get a
  bat that has more mass. Therefore the more mass
  or acceleration you have the more force youll
  have.

11
MF/A

• MF/A . An example of this would if you had a lot
  of force and acceleration you would have a lot of
  mass.

12
AF/M

• AF/M. An example of this would be if you had a
  lot of force and mass you would have a lot of
  acceleration.

13
WMG

• WMG. An example is if you had a lot of mass and
  a lot of gravity youll get a lot of weight.

14
MW/G

• MW/G. An of this would be if you had a lot of
  weight and gravity youll end up with a lot of
  mass.

15
GW/M

• GW/M. An example of this would be if you had a
  lot of weight and mass youll have a lot of
  gravity.
