Title: The Dynamics of Newton's Laws

1
The Dynamics of Newtons Laws
• By Casey Frerichs

2
Magnetic Force
• Magnetic forces like electric forces are very
large in comparison to gravitational forces. In
fact magnetic forces are produced by moving
electric charges. Electric and magnetic forces
are very closely related. At the present time
this relationship is not completely understood.

3
Electric Force
• The force that appears when you push something
with your hand is an electric force. The electric
force of repulsion develops as the electrons of
an object. In the same way the force between an
automobiles tires and the road is an electric
force.

4
Gravitational Force
• Gravitational force is an extremely weak force in
comparison to the other forces. If two tennis
balls are held one meter apart the gravitational
force between them is only 0.00000000001 newtons.

5
Weak interaction and Nuclear Force
• Nuclear force is much stronger than all the other
forces. The nuclear force holds the nucleus of an
atom together in a spite of the strong force of
repulsion. There is a second force inside the
nucleus. It is called the weak interaction.

6
Newton's First law
• It is that an object continues to move or rest
unless it is acted upon by an outside force. An
example is throughing a ball and someone catching
it in a glove.

7
Newtons Second law
• Newtons second law states that when an
unbalanced force acts on a body it will
accelerate. An example is when u hit a baseball
the ball will accelerate.

8
Newtons Third law
• His third law is that every force is joined by an
equal and opposite force. An example is two
people pushing against each other.

9
FMA
• It is that force equals mass times acceleration.
An example and a car and its weight and its
acceleration

10
MF/A
• It is mass equals force divided by acceleration.
The force of the car and the acceleration would
get you the mass.

11
AF/M
• It is that the acceleration equals the force
divided by the mass. You would take the force
divided by the mass of the car to get the cars
acceleration.

12
WMG
• You get the weight by multiplying the mass by the
gravitational pull. You take the gravity on a car
and the mass to get the weight of the car.

13
MW/G
• Its that mass equals the weight divided by the
gravitational pull on an object. The mass of car
is the weight divided by the gravity.

14
GW/M
• It is that the gravity equals the weight divided
by the mass. To get the gravitational pull on a
car you would divide the weight by the mass of
the car.
