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.
