Title: the dynamics of newtons laws


1
The Forces of Motion
  • Tiffany Short
  • Mr.Frazier (Homeroom)
  • 7th Grade

2
Gravitational Force
  • Definition- the forces of attraction in the
    universe.

3
Magnetic Force
  • Associated with electric currents as well as
    magnets.

4
Electric Force
  • An attractive or repulsive electrostatic force.

5
Newtons Three Laws of Motion
6
1st Law of Motion
  • First law- The First law of motion An object in
    motion stays in motion, an object at rest stays
    at rest unless acted on by an outside force

7
Second Law
  • Second law The acceleration of a body is
    directly proportional to, and in the same
    direction as, the net force acting on the body,
    and inversely proportional to its mass. The ma,
    where F is the net force acting on the object, m
    is the mass of the object and a is the
    acceleration of the object

8
Third Law
  • Third law When one body exerts a force on a
    second body, the second body simultaneously
    exerts a force equal in magnitude and opposite in
    direction to that of the first body.

9
Newtons laws and how they pertain to history
  • The first law of motion is just like a tool the
    Greeks invented. A Catapult.
  • The second law of motion

10
Dynamics
  • Dynamics is the study of forces which cause
    motion.

11
Other Forces
  • There are other forces than Gravitational,
    Electric, Magnetic The two forces are Nuclear
    and Weak Interaction but they are rarely observed
    because they exist only inside the Nucleus.

12
WMxG
  • A force accelerates a mass.
  • A force is measured in terms of the acceleration
    it gives a standard mass.
  • For example- You would have to multiply 12x12144

13
MW/G
  • A force accelerates a mass.
  • A force is measured in terms of the acceleration
    it gives a standard mass.
  • For an example you would need to divide 45/95 .

14
GW/M
  • A force accelerates a mass.
  • A force is measured in terms of the acceleration
    it gives a standard mass.
  • For an example 50/105 .

15
FMxA
  • A force accelerates a mass.
  • A force is measured in the terms of acceleration
    it gives a standard mass.
  • For example 3x1030.

16
MF/A
  • A force accelerates a mass.
  • A force is measured in terms of acceleration it
    gives a standard mass.
  • For example 80/108.

17
AF/M
  • A force accelerates a mass.
  • A force is measured in the terms of acceleration
    it gives a standard mass.
  • For example 40/104.
