Dynamics and Newton's Laws

• By Bryan McGuire

2
Electrical Forces

• The result of electron repulsion between two
  objects
• These are forces that were see all the time but
  dont usually recognize it.
• They are actions such as simply a handshake, high
  five, and fist pump.

3
Magnetic Forces

• Produced from electrical charges
• They are the control almost everything in the
  universe.
• One example is the moon and earth that are
  pulling along with each other

4
Gravitational Forces

• Weakest of all forces
• What holds the planets in orbit
• Stronger on earth than moon

5
Nuclear and Weak Interaction forces

• The most unnoticed two forces
• Both happen in nucleus of atoms
• The effects though are very noticeable

6
Newton's first law of motion

• Newton's first law states that an object in
  motion stays in motion and an object at rest
  stays at rest unless acted on by an outside force
• Throwing a ball that doesnt stop until someone
  stops it

7
Newtons second law of motion

• Newtons second law of motion states that
  acceleration equals force times mass
• A truck of 3000 pounds hits a 4000 pound truck
  each going same speed the 4000 pound will take
  less damage

8
Newtons third law of motion

• Every action will have an equal and opposite
  reaction
• The gravitational pull on the earth and moon

9
mass

• Mass is how much space an object takes up

10
F MA

• This formula shows that the mass of an object
  times the acceleration equals the force.
• An example of this is a mans mass times the
  acceleration to equal force

11
Af/m

• The acceleration equals force divided by mass
• For example a cars force divided by the mass of
  the car will show the acceleration of the vehicle

12
WMG

• The weight is equal to mass times the
  gravitational pull
• A person weighs less on the Moon than on Earth

13
Mw/g

• The mass is equal to the weight divided by the
  gravitational pull
• The mass of the car is defined by the weight of
  the car divided by gravitational pull on the car.

14
Gw/m

• Gravitational pull equals weight divided by mass
• For example gravitational pull is found by
  dividing your weight by mass
