Title: The Dynamics Of Newton's Laws

1
The Dynamics Of Newtons Laws
• By Kayleigh Morton

2
Magnetic Force
• Attraction for iron associated with electric
currents as well as magnets characterized by
fields of force
• Example-North and south poles coming together.

3
Electric Force
• Something that exerts a force on another.
• Example-When two people are standing shoulder to
shoulder and one is pushed the electricity will
go through one person through the other pushing
them both.

4
Gravitational Force
• The force of attraction between all masses in the
universe.
• Example-When you jump up and you come straight
back down.

5
Weak Interaction And Nuclear Force
• It is most commonly thought to be the cause of
beta decay and the associated radioactivity.
• Example-It is hard to view this because it is
located in the nucleus.

6
Newtons First Law
• First law of motion a body remains at rest or in
motion with a constant velocity unless acted upon
by an external force.
• Example-A pall is still and when you push it it
moves until something stops it.

7
Newtons Second Law
• Second law of motion the rate of change of
momentum is proportional to the imposed force and
goes in the direction of the force.
• Example-How hard you push a ball. It goes from 0
to however hard you push it.

8
Newtons Third law
• Action and reaction are equal and opposite.
• Example-If two balls hit each other traveling at
the same speed and have the same mass theyll
stop.

9
FMxA
• Mass x Acceleration
to push it to the side of the rode.

10
MF/A
• Force divided by acceleration.
• Example-A car, what the force and the
acceleration is. Then you can get the mass.

11
AF/M
• Force divided by mass.
• Example-How far a ball would go.

12
WMxG
• Mass x Gravity
• Example-To know the weight of a car you have to
know the mass and multiply it by its gravity.

13
MW/G
• Weight divided by gravity.
• Example-A boulder, you have to divide the weight
of the boulder by the gravity.

14
GW/M
• Weight divided by mass
• Example-A house, you have to know the weight and
the mass of the house to know how much gravity.
