Title: The Dynamics Of Newton's Laws

1
The Dynamics of Newtons Law
• By Preston Crump

2
Magnetic Force
• Magnetic forces are produced by moving
electrical charges.
• Magnetic and electric forces are very closely
related.

3
Electric forces
• The force that appears when you push something is
electric force.
• This type of force develops as electrons of the
hand is brought close to the electrons of an
object.

4
Gravitational force
• This type of force is extremely weak compared to
the other forces.
• This force happens when things fall.

5
Weak interaction and nuclear
• Nuclear force is much stronger than any other
force. This force holds together the nucleus of
an atom together.
• Scientists believe that a second force exists in
the nuclei of an atom. Weak interaction is
believed to be the force that breaks atoms apart.

6
Newtons first law
• Newtons first states that and object in motion
will stay in motion and an object at rest will
stay at rest unless an outside force is acted
upon it.
• If you were to throw a ball the ball would keep
going until friction in the air stops it.

7
Newtons second law
• Newtons second law states that when an
unbalanced force acts upon a body the body will
accelerated.
• For example if you were to hit a ball the ball
would go in the direction that the objects force
is going

8
Newtons third law
• Newtons third law states that for every action
there is an equal and opposite reaction.
• For example when you shoot a gun the gun will
shoot but also push back on you in the form of
recoil.

9
Fma
• Force is equal to the mass times the acceleration
of an object.
• That means that if a car mass of 1000 N and it
is accelerating by 20 N its force would be 2O,OOO.

10
Mf/a
• This formula means that mass is equal to the
force of an object divided by its acceleration.
• An example of this is if a car has a force of
2000 N and an acceleration of 40 N its mass would
be 50

11
Af/m
• This means that an objects acceleration can be
found by dividing its force by its mass.
• For example if a car has a force of 100 N and a
mass of 10 N its acceleration would be 10 N

12
Wmg
• This formula states that an objects weight can be
found by dividing its mass by its gravitational
pull
• For example if a car has a mass of 100 N and a
gravitational pull of 10 N then its weight would
be 10 N.

13
MW/G
• This means that an objects mass is equal to the
weight of an object divided by its gravitational
pull.
• For example if a car weighs 100 N and has a
gravitational pull of 5 N its mass is 20.

14
G w/m
• This formula means that an objects gravitational
pull is equal to its weight divided by its mass.
• For example if a car has a weight of 100 N and a
mass of 10 N its gravitational pull is 10 N.
