Title: The Dynamics of Newtons Laws


1
The Dynamics of Newtons LawsDynamics is the
study of forces which cause motion
  • By Callie Arnold and Amy Ginter

2
Magnetic Force
  • A force that exists between two electrically
    charged moving particles.
  • They are very large compared to gravitational
    forces.
  • Electric and magnetic forces are very closely
    related.

3
Electric Force
  • Very large.
  • Produces magnetic forces by moving electric
    charges.
  • Results from electron repulsion of two objects.

4
Gravitational Force
  • The weakest of all the forces.
  • It is very small compared to magnetic and
    electric forces.

5
Weak Interaction and Nuclear Force
  • The strongest of all the forces.
  • Some power plants use nuclear power to provide
    electricity to cities today.
  • Holds the nucleus of an atom together.

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.
  • If you roll a tennis ball on the floor it will
    keep going unless its acted on by an outside
    force.

7
Newtons Second Law
  • When an unbalanced force acts on a body, the body
    will be accelerated.
  • Two cars, one at rest and one driving in a
    straight line, and they collide. The car at rest
    is acted upon by the moving car.

8
Newtons Third Law
  • Every force is accompanied by an equal and
    opposite force.
  • A charged body repels another body.

9
FMA
  • Force equals mass times acceleration
  • If the force of your hammer on a nail is 36, then
    your mass and acceleration would be 6.

10
MF/A
  • Mass equals force times acceleration
  • If your mass of the hammer is 8, then your force
    could be 32 and your acceleration could be 4.

11
AF/M
  • Acceleration equals force divided by mass
  • If the acceleration of your hammer is 12, then
    your force could be 144 and your mass could be 12

12
WMG
  • Weight equals mass times gravity
  • If your weight is 48, then your mass could be 12,
    and your gravity could be 4.

13
MW/G
  • Mass equals weight divided by gravity
  • If your mass is 11, then your weight could be 22
    and your gravity would be 2.

14
GW/M
  • Gravity equals weight divided by mass
  • A car could have the gravity of 100, weight of
    200, and mass of 2.
