Title: Dynamics Of Newtons Laws


1
Dynamics of Newton's Laws
  • Study of forces which cause motion.

2
Magnetic Force
  • Produced by moving electrical charges

3
Electric Force
  • Force that appears when you push something

4
Gravitational Force
  • the force of attraction between all masses in the
    universe especially the attraction of the
    earth's mass for bodies near its surface

5
Weak Interactions
  • an interaction between elementary particles that
    is responsible for certain decay processes,
    operates at distances less than about 10-15
    metres, and is 1012 times weaker than the strong
    interaction. The weak interaction and
    electromagnetic interactions are now described by
    the unifying electroweak theory Also called weak
    nuclear interaction, force.

6
Nuclear Forces
  • Strong interaction.

7
Newton's First Law
  • An object at rest stays at rest and an object in
    motion stays in motion with the same speed and in
    the same direction unless acted upon by an
    unbalanced force.

8
Newtons Second Law
  • The acceleration of an object as produced by a
    net force is directly proportional to the
    magnitude of the net force, in the same direction
    as the net force, and inversely proportional to
    the mass of the object.

9
Newton's Third Law
  • For every action, there is an equal and opposite
    reaction.

10
FMxA
  • Force Mass times Acceleration

11
FMxA
  • ForceMassAcceleration

12
AF/M
  • Acceleration Force divided by Mass

13
WMxG
  • Weight MassGravity

14
MW/G
  • Mass Weight divided by gravity.

15
GW/M
  • GravityWeight/Mass
