Title: The Dynamics of Newton's Law E. Compton


1
The Dynamics of NewtonsLaws
  • By E. Compton

2
Forces of Motion
  • Dynamics is the study of forces of motion.

3
Magnetic Force
  • A magnetic force a force that exists between two
    electrically charged moving particles.
  • Ex.

4
Gravitational Force
  • The force of attraction between all masses in the
    universe.
  • Ex.

5
Electric Force
  • The force that appears when you push on something
    with your hand is an electric force.
  • Ex.

6
Nuclear and Weak Interactions
  • They are too small to see.

7
Newtons First Law ofMotion
  • An object in motion will stay in motion and in
    object at rest will stay at rest unless acted
    upon by an outside force.
  • Real Life Ex.

8
Newtons Second Law ofMotion
  • The rate of change of momentum is proportional to
    the imposed force and goes in the direction of
    the force.
  • Real Life Ex.

9
Newtons Third Law ofMotion
  • A force is a push or a pull upon an object that
    results from its interaction with another object.
  • Real Life Ex.

10
FMxA
  • FMxA is force equals mass times acceleration.
  • Ex. A 300g cart reaches a speed of 50m/s in 20
    seconds from a standing start.

11
AF/M
  • This formula is acceleration equals force times
    mass.
  • An example of this is Jonathon has an engine that
    can provide a force of 5.6 newtons.

12
WMG
  • This formula is weight equals mass times gravity.
  • Ex. An example of this formula is this is.
  • An object with a mass of one kilogram has a
    weight of about 9.8

13
WM/G
  • This formula is weight mass x gravity

14
GWxM
  • This formula is mass time weight equals gravity.
