Title: The Dynamics of Newton's Laws

1
The Dynamics of Newtons Laws
• The study of Forces Which Cause Motion.
• By Benjamin N. Rose

2
Magnetic Force
• Large compared to gravitational forces.
• Produced by electric charges.
• Closely related to electric forces.

3
Electric Force
• Electric force is also stronger compared to
gravitational forces.
• An example is pushing a chair.

4
Gravitational Force
• The weakest force
• If two tennis balls are held one meter apart, the
gravitational force between them is 0.00000000001
newtons.

5
Weak Interaction/Nuclear Force
• The two strongest forces.
• Both forces act in the nuclei of atoms.
• The nuclear force is what holds an atom apart.
• The weak interaction force is what tries to split
them apart.
• They are also the hardest forces to
observe-especially weak interaction.

6
Newtons First Law
• This law is also known as the law of inertia.
• The law states that a body at rest, stays at
rest, and that a body in motion stays in motion,
unless acted upon by another force.
• An example of this is say a ball sits in space is
being acted upon by no force. It is at rest. But,
a force has acted on it now it is in motion and
unless it is stopped by another force it will go
on forever.

7
Newtons Second Law
• This law states that when a unbalanced force acts
on a body, the body will be accelerated.
• An example of this is when one force is having a
stronger effect on an object than another like a
rocket blasting off into space. The rockets
electric force is stronger than earths
gravitational force.

8
Newtons Third Law
• This law is also known as the law of action and
reaction.
• The law states that a single force can never
exist. Every force is accompanied by an equal and
opposite force.
• An example is the Earth and the Moon. Even though
the Earth has more mass, the moon is still coming
at it with an equal amount of force.

9
FMxA
• This equation represents force equals mass times
acceleration.
• An example of this is if you add mass to an
object versus another object of smaller size.
This would cause the smaller object to have more
acceleration.

10
MF/A
• It is just another example of FMxA.

11
AF/M
• Also just another example of FMxA.

12
WMxG
• This means weight equals mass times the
• Acceleration of gravity.
• If an object was 10g on earth it would weigh 98
newtons.

13
MW/G
• This formula finds the magnitude of force.
• Same result as wmxg.

14
GW/M
• Also for finding magnitude of force.
• Same result as wmxg.
