Title: The Dynamics of Newton's 3 Laws

1
The Dynamics of Newtons Laws
• By Ryan Thomas

2
Magnetic Force
• Magnetic forces are very large in comparison to
gravitational forces. Magnetic forces are caused
by moving electrical charges. Magnetic and
electric forces are very closely related.

3
Electric Force
• The force that appears when you push on something
with your hand is an electric force. This
electric force of repulsion develops as the
electrons of the hand are brought close to the
electrons of an object.

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 Nuclear Force
• Nuclear forces are much stronger than any of the
other forces. The nuclear force holds the nucleus
of an atom together in spite of the strong
electric force of repulsion between its protons.
• The second force inside a nucleus is the weak
interaction force. This is the force believed to
break some atoms apart.

6
Newtons 1st Law of Motion
• A body continues in its state of rest, or of
uniform motion in a straight line, unless its
acted upon by a net eternal force.
• Example When youre riding in a car and the car
stops your body lunges forward because it wants
to continue moving.

7
Newtons 2nd Law of Motion
• When an unbalanced force acts on a body, the body
will be accelerating.
• Example when you hit a golf ball is hit by a
golf club the ball goes in the direction you hit
the ball.

8
Newtons 3rd Law of Motion
• Every force is accompanied by an equal and
opposite force.
• Example When you hit a baseball with a baseball
bat, the ball goes further than the ball because
you hit the ball with more force than the ball

9
FMA
• This means that force equals mass times
acceleration.
• Example The force that was exerted on the car is
found by multiplying the cars mass times the
acceleration it has.

10
M F/A
• This means mass equals force divided by
acceleration.
• Example The mass of a car is found by dividing
the force exerted on the by the acceleration of
the car.

11
A F/M
• This means that acceleration equals force divided
by mass.
• Example The acceleration of a car is found by
dividing the force exerted on the car by the mass
of the car.

12
W MG
• This means that weight equals mass times
gravitational pull.
• Example Your weight is found by multiplying your

13
M W/G
• Mass is found by dividing your weight by your
gravitational pull.
• Example Your mass is found by dividing your
