Dynamics of Newton's laws.

The dynamics of Newtons law

• By Colton Markland

Dynamics

• The study of forces which cause motion.
• Dynamics deal with the cause of motion rather
  than motion itself.
• There are 5 total forces ,gravitational,
  magnetic, electric, nuclear, and weak
  interactions, but I am only going to talk about
  gravitational, magnetic , and electric because
  they are way more observable than the other to
  because they are small and only exist in the
  nucleus.

Gravitational force

• This is the weakest and most observable of the
  forces.
• If you have two basketballs and you drop them at
  the same time, they will hit the ground at the
  same time. That would be gravitational.

4
Magnetic force

• Performed between a cross distance in space
  between two magnets.
• These are produced by moving electric charges.
• If you put two magnets north and north of each
  other, they will push away from each other. That
  is an example of magnetic force.

5
Electric forces

• The force that occurs when electrons push
  together.
• The biggest observable force.

6
Newtons first law

• A body continues in its state of rest, or of
  uniform motion in a straight line, unless it is
  acted upon by a net external force.
• A body in motion tends to stay in motion, a body
  at rest tends to stay at rest.
• An example would be when you are passing the
  football. If who ever you are passing it to
  wasnt where you threw it, then there would be
  nothing there to stop the ball. It would keep
  going. It would stay in motion.

7
Newtons second law

• The acceleration of an object produced by a net
  (total) applied force is directly related to the
  magnitude of the force, the same direction as the
  force, and inversely related to the mass of an
  object.
• An example of this would be when you are pulling
  a box and you pull a larger box and then a
  smaller box. You get a higher acceleration when
  you pull the smaller box than the bigger box.

8
Newtons third law

• For every action (force) there is an equal and
  opposite reaction (force).
• When you sit in a chair, your body exerts a force
  downward and that chair needs to exert an equal
  force upward or the chair will collapse.

9
F MA

• This is associated with Newtons second law.
• The more force, the more acceleration.
• Like when you are playing baseball if you want to
  hit the ball farther, you increase the
  acceleration or the mass.

10
MF/A

• Force equals mass times acceleration.
• When you are trying to hit a baseball, you apply
  more force to it.

11
AF/M

• Acceleration equals force divided by mass.

12
WMG

• Weight equals mass times gravity.

13
MW/G

• Mass equals weight divided by gravity.

14
GW/M

• Gravity equals weight divided by mass.
