Title: The Dynamics Of Newton's Laws(Haley Prater)

1
The Forces Of Motion
• By Haley Prater
• Mr. Frazier
• Social Studies

2
Gravitational Force
• Definition- The force of attraction between all
masses in the universe especially the attraction
of the earth's mass for bodies near its surface.

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

4
Electrical Force
• Definition- An attractive or repulsive
electrostatic force.

5
Newtons Three Laws Of Motion
• By Haley Prater

6
First Law
• Definition- An object in motion will stay in
motion, an object at rest will stay at rest
unless acted on by an out side object

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. Thus, F
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 Pertain to History class
• The First law of motion is just like a tool the
Greeks invented. A catapult.
• The Second law is like a Ox drawn plow.
• The third law relates to a ice skating.

10
The study of forces which cause motion.
Dynamics
11
Other Forces
• There are other forces than magnetic, electric,
and gravitational, but they arent observable.
They are nuclear, weaker interaction and stronger
interaction. They are rarely observed because
they exist only inside the nucleus.

12
FMxA
• The formula would be used to get the force. You
will multiply mass times acceleration, and then
get the total amount of force that is applied.
• If the mass is 20g, and the acceleration is 40g.
You multiply them together. So the amount of the
force is 800g.

13
MF/A
• The formula would be used to get the force. You
will divide force by acceleration, and then get
the total amount of mass that is applied.
• If the force is 700, and the acceleration is 7.
You divide 700/7. the amount of mass would be
100.

14
AF/M
• The formula would be used to get the
acceleration. You will divide force by mass, and
then get the total amount of acceleration that is
applied.
• If the force is 80, and the mass is 2. You divide
80/2. The amount of acceleration would be 40.

15
WMxG
• The formula would be used to get the weight. You
will multiply mass by gravity, then get the total
amount of weight that is applied.
• If the mass is 0, and the gravity is 300 . You
multiply 0x300. The amount of weight would be
300.

16
MW/G
• The formula would be used to get the mass. You
will divide weight by gravity, then get the total
amount of mass that is applied.
• If the weight is 3, and the gravity is 1 . You
divide 1/3. The amount of mass would be 3.

17
GW/M
• The formula would be used to get the amount of
gravity. You will divide weight by mass, then get
the total amount of gravity that is applied.
• If the weight is 70, and the mass is 7 . You
divide 70/7. The amount of gravity would be 10.
