Title: Newton's laws


1
The dynamics of Newton's laws
2
Magnetic Force
  • Magnetic forces are produced by moving electric
    charges.

3
Electric Force
  • The force that appears when you push on
    something with your hands is electric force. This
    electric force of repulsion develops as the
    electrons of the hand are brought close to the
    electrons of an object.

4
Gravitational Force
  • Gravitational force is an extremely weak force
    in comparison to the other forces.

5
Weak Interaction and Nuclear Forces
  • Nuclear forces are much stronger than other
    forces. The nuclear force holds the nucleus of an
    atom together in spite of the strong electric
    force of repulsion between its protons.

6
Newton's first law
  • His first law of motion states, 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.

7
Newton's second law
  • the second law says that the acceleration of an
    object produced by a net 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.

8
Newton's third law
  • The third law says that for every action there
    is an equal and opposite reaction. Forces are
    found in pairs.

9
FMxA
  • The more force the more acceleration. F force,
    A acceleration, M mass.

10
M F/A
  • m mass, f force, a acceleration

11
AF/M
  • A acceleration, F Force, M mass. This means
    acceleration equals force divided by mass.

12
W MxG
  • W means weight, M means mass and G means
    gravity. This means weight equals mass multiplied
    by gravity.

13
M W/G
  • M means mass, W means weight, and G means
    gravity. This means that mass equals weight
    divided by gravity.
