dynamics of newtons laws of motion

1
The Dynamics of Newton's Laws

• By J. barber

2
Gravitational force

• This force is the force of gravity.
• The force pulls objects together.
• This force pulls us down to earth.
• In space there is no Gravity.

3
Electrical forces

• The Electrical force is used mostly for power.
• They are used in Batteries, wires, and even a
  laptop.
• There are different types of Electricity.
• Solar and Wind electricity are some examples,

4
Magnetic force and some others

• This force happens when a magnetic field is
  present.
• This reacts to certain metals.
• For example two magnets will attract to each
  other.
• Two other forces are nuclear and weak interaction
  forces.

5
Newton's 1st law of motion

• The first law is an object at rest will stay at
  rest and an object in motion will stay in motion
  unless acted on by an outside force.
• This law is also called the law of inertia.
• It is when an object is resisting to move against
  the force.

6
Newton's 2nd Law

• This law is the relationship between force,
  speed, and acceleration.
• AF/M
• One example of this is when your knocking on a
  door if no one can hear you then you increase
  your speed and then people might be able to hear
  you.

7
Newtons 3rd Law

• Newtons 3rd Law is For every action there is an
  equal but opposite reaction.
• This means when you do something you will effect
  something oppositely.
• For example when a rocket is taking off the fire
  is the action and the rocket flying is the
  reaction.

How to calculate force(Formula)

• The way you get force is force equals mass times
  acceleration.
• Formula FMA
• Or forcemassacceleration
• Ex. When your hitting a baseball you will use
  more force to make it go farther

9
How to calculate acceleration(formula)

• To calculate acceleration you must do force
  divided by the mass.
• The formula is AF/M
• Another way you can think of it is
  accelerationForce divided by the mass.
• When the car starts to move thats the
  acceleration.

10
How to calculate the magnitude(formula)

• The way that you calculate mass is you take the
  force divided by the acceleration which will give
  you the mass.
• Formula MF/A
• Or magnitudeforce/acceleration
• How high that you go.

11
How to calculate weight(formula)

• You would have to do mass times gravity
• Formula WMG
• Or weight mass gravity
• How heavy an object is.

12
Calculating mass

• You would do weight divided by gravity
• MW/G
• Or mass weight/gravity
• How much space it takes up.

13
How to calculate gravity

• You would do weight divided by mass
• Formula GW/M
• Gravityweight/mass
• Pulls objects together.
