Title: The Dynamics of Newton's Laws


1
The Dynamics of Newtons Laws
  • Mikayla Peyton

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.
