Title: the dynamics of newtons laws

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

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.
