Title: The Dynamics of Newtons Laws lholder


1
The dynamics of Newton's Laws
  • By Landen Holder

2
Magnetic force
  • Magnetic forces are produced by moving electrical
    forces
  • Magnetic and electrical forces are very close
    related

3
Electric force
  • An electric force is produced when you push
    something
  • The electric force of repulsion develops when the
    electrons in your hand are brought close to the
    electrons of an object

4
Gravitational force
  • Gravitational force is extremely weak compared
    tot the other forces
  • Gravitational force is when an object is
    attracted to another larger object

5
Weak interaction and nuclear force
  • Nuclear forces are much stronger than any of the
    other forces
  • This force holds together the nucleus of an atom
  • Scientists believe that a force exists inside the
    nucleus of atoms called weak interaction
  • It is believed to be the force that causes atoms
    to break apart

6
Newton's first law
  • Newton's first law states that an object in
    motion will stay in motion and an object at rest
    will stay at rest unless acted upon by an outside
    force
  • Throw a baseball and someone catches it to stop it

7
Newton's second law
  • A force on an object will move the object in the
    direction of the force
  • An example of this is a person hitting a golf
    ball with a golf club and the ball traveling in
    the direction of the club

8
Newton's third law
  • Every action has an equal and opposite reaction
  • An example of this would be a rocket taking off.
    The force is the blast of ignited fuel and the
    reaction is the rocket shooting upwards

9
F M x A
  • This formula means that force equals the mass
    times the acceleration of an object
  • This means that if a car has a mass of 1000 N and
    it is accelerating by 20 N its force would be
    20,000 N

10
M F / A
  • This formula means that mass is equal to force of
    an object divided by its acceleration
  • An example is a football with a force of 50 N and
    its traveling at 10 N its mass is 5 N

11
A F / M
  • This formula means that an objects acceleration
    can be found by dividing its force by its mass
  • An example is if a car has a force of 600 N and
    its mass is 200 N its acceleration is 3 N

12
W M x G
  • This means that weight is equal to the mass of an
    object multiplied by the gravitational force
    acting on it
  • For example is a vehicles mass is 25 N and their
    gravitational pull from the Earth is 30 N their
    weight is 750 N

13
M W / G
  • This means that an objects mass is equal to the
    weight of an object divided by its gravitational
    pull
  • For example if a car weighs 100 N and has a
    gravitational pull of 10 N its mass is 10 N

14
G W / M
  • This formula means that the gravitational pull on
    an object is equal to its weight divided by its
    mass
  • For example if a car has a weight of 25 N and its
    mass is 5 N its gravitational pull on the car is
    5 N
