The Dynamics of Newtons Laws

2
Magnetic Force

• Magnetic force is large when compared to
  gravitational force
• A magnetic force occurs when a force is exerted
  between magnetic poles
• Its also a force which exist between two
  electrically charged particals

3
Electric force

• Electric force is the most observable of all
  forces.
• An electric force occurs when a force is exerted
  on an object.

4
Gravitational Force

• A gravitational force is the force of attraction
  of all masses.
• Its also the force that holds you to Earth

5
Nuclear and weak interaction forces

• Nuclear forces only occurs within the nucleus of
  an atom
• Scientists believe that another force exists
  within the nucleus of an atom, this is called the
  weak interaction force

6
Newtons 1st law of motion

• An object in motion stays in motion unless acted
  upon by an outside force. An object at rest stays
  at rest unless acted upon by an outside force.
• Newtons 1st Law of Motion is also known as the
  Law of Inertia
• When you are riding in a car and the car stops,
  you still move forward. This is because of
  inertia

7
Newtons 2nd law of motion

• When an unbalanced force acts upon a body, the
  body is then accelerated
• An example of this is you and your friend are
  sitting in a chair with your feet up, you push
  your feet against theirs, the person with more
  mass pushes with more force therefore sending the
  other person faster when they push off

8
Newtons 3rd law of motion

• For every action there is an opposite and equal
  reaction
• One example of this is If a 3,000 pound car
  crashes into a 5,000 car the 3,000 pound car is
  more likely to have more damage

9
F M x a

• Force equals mass times acceleration
• If a driver pushes a car that ways 3,000 pounds
  with a mass 0.5 then the force exerted is 1,500

10
M f/a

• Mass equals force divided by acceleration
• If an engine exerts 6.0 newtons of force, and
  its placed on a cart that accelerates at 3.5,
  then the mass would be 1.71

11
A f/m

• Acceleration equals force divided by mass
• A ball that is thrown with a force of 8 newtons,
  if the mass is 4 then the acceleration of the
  ball would be 2

12
W m x g

• Weight equals mass times gravity
• If a rock has a mass of 10, then and the amount
  of gravity pulling on the rock is 2, then the
  rock would way 20 poounds

13
M w/g

• Mass equals weight divided by gravity
• If a rock weighs 20 pounds, and the gravity
  pulling on the rock is 2, then the mass would be
  2.

14
G w/m

• Gravity equals weight divided by mass
• If a rock weighs 20 pounds, and the mass is 2
  then the gravity pulling on it would be 2.
