Newton's dynamics and laws of motion

1
The dynamics of Newtons laws

• By Justin Arnett

2
dynamics

• Dynamics is the study of forces which cause
  motion

3
Gravitational forces

• The first one is gravitational is the smallest
  most observable. Say you held two tennis balls in
  the air and drop them they will land at the same
  time.

4
Magnetic forces

• Produced by moving electrical forces
• Example-two magnets pulling toward each other in
  space

5
Electrical forces

• The force that occurs when pushing on electrons
• The biggest observable force
• A nucular force and weak reaction forces are
  unobservable because they are located in the
  nucleus

6
Newtons 3 laws

• By Justin Arnett

7
Newtons first law

• An object at rest must stay at rest unless acted
  upon by an opposing force
• An object in motion must stay in motion unless
  acted upon by an opposing force
• Example-when you are playing football if you
  dont catch it will go past you

8
Newtons 2 law

• Acceleration occurs by Appling force to the
  magnatude of the force
• Example-you get more acceleration from pulling a
  small box instead of a large bog

9
Newtons 3 law

• For every action there is an opposing action
  force
• Example-when you sit in a chair you produce a
  force downward and the chair produces an opposing
  force

10
Formulas

• By Justin Arnett

11
Fma

• Is how the second law of motion is often written
• Example- when you are playing baseball if you
  want to hit the ball farther you increase the
  acceleration or the mass of the bat

12
Mf/a

• MF/A
• Mass equals force divided by acceleration

13
AF/M

• AF/M
• Acceleration equals force divided by Mass

14
WMG

• WMG
• Weight equals mass times gravity

15
MW/G

• MW/G
• Mass equals weight divided by gravity

16
GW/M

• GW/M
• Gravity equals weight divided by mass
