Title: the dynamics of Newton's laws by b. patrick

1
The dynamics of Newtons laws.
• By B.Patrick

2
Magnetic force
• Magnetic forces are produced with magnets, and
Electrical charges.
• Electrical and magnetic forces are closely
related to each other, and still to this day it
is not completely understood.
• Example A rocket having a magnet in front of it
and behind it.

3
Electric forces
• Electric force is when you push on something with
• This force of repulsion develops as electrons.
• Example You knock over one domino then that
domino hits another then it goes on and on till
all of the dominos are knocked over.

4
Gravitational force
• Gravitational force is the weakest force that we
can see.
• If two tennis balls are held 1 meter apart then
the gravitational pull would be 0.00000000001
Newton's.
• Example Dropping a book on the floor.

5
Weak interaction and nuclear force
• Nuclear forces are the strongest forces, but they
are so small that we cant see it happen.
• This force holds the nucleus of atoms together.

6
Newton's first law of motion
• Newton's first law of motion stats that an object
in motion will stay in motion and an object at
rest will stay at rest until acted upon by an
outside force.
• Example you drive a car and then you stop and

7
Newtons seconded law of motion
• Newtons seconded law of motion states that the
acceleration of an object produced by a net
applied force is directly related to the
magnitude of the force.
• Example you role a ball and there are two forces
acting on it gravity and friction.

8
Newtons third law of motion
• Newtons third law of motion states that for
every action there is an opposite but equal
reaction.
• Example A rocket going up into outer space using
thrusters.

9
F(m)A
• The mass of an object times acceleration of an
object will equal the force of the object.
• Example a car moving 60 miles per hour weighs
200,000 pounds. 60 200,000 the force.

10
M F/A
• The force of an object divided by the
acceleration of an object equals the mass of the
object.
• Example a car hits a wall traveling 40 miles per
hour with a force of 3,000 psi (pounds per square
inch). 403000

11
A F/M
• Force divided by mass equals acceleration.
• Example if the force is 20 and the mass is 5
then the acceleration is 4.

12
W MG
• This formula is weight equals mass times gravity.
• If the mass of an object is 20 and the
gravitational pull is .5 then the weight is 10

13
MW/G
• This formula is mass equals weight divided by
gravity .
• Example if gravity is .5 and the weight is 50
then the mass is 100

14
GW/M
• This formula is gravity equals weight divided by
mass.
• Example if the weight is 50 and the mass is 200
then the gravitational pull is 4.
