Title: The Dynamics Of Newton's Laws


1
The Dynamics of Newtons Law
  • By Preston Crump

2
Magnetic Force
  • Magnetic forces are produced by moving
    electrical charges.
  • Magnetic and electric forces are very closely
    related.

3
Electric forces
  • The force that appears when you push something is
    electric force.
  • This type of force develops as electrons of the
    hand is brought close to the electrons of an
    object.

4
Gravitational force
  • This type of force is extremely weak compared to
    the other forces.
  • This force happens when things fall.

5
Weak interaction and nuclear
  • Nuclear force is much stronger than any other
    force. This force holds together the nucleus of
    an atom together.
  • Scientists believe that a second force exists in
    the nuclei of an atom. Weak interaction is
    believed to be the force that breaks atoms apart.

6
Newtons first law
  • Newtons first states that and object in motion
    will stay in motion and an object at rest will
    stay at rest unless an outside force is acted
    upon it.
  • If you were to throw a ball the ball would keep
    going until friction in the air stops it.

7
Newtons second law
  • Newtons second law states that when an
    unbalanced force acts upon a body the body will
    accelerated.
  • For example if you were to hit a ball the ball
    would go in the direction that the objects force
    is going

8
Newtons third law
  • Newtons third law states that for every action
    there is an equal and opposite reaction.
  • For example when you shoot a gun the gun will
    shoot but also push back on you in the form of
    recoil.

9
Fma
  • Force is equal to the mass times the acceleration
    of an object.
  • That means that if a car mass of 1000 N and it
    is accelerating by 20 N its force would be 2O,OOO.

10
Mf/a
  • This formula means that mass is equal to the
    force of an object divided by its acceleration.
  • An example of this is if a car has a force of
    2000 N and an acceleration of 40 N its mass would
    be 50

11
Af/m
  • This means that an objects acceleration can be
    found by dividing its force by its mass.
  • For example if a car has a force of 100 N and a
    mass of 10 N its acceleration would be 10 N

12
Wmg
  • This formula states that an objects weight can be
    found by dividing its mass by its gravitational
    pull
  • For example if a car has a mass of 100 N and a
    gravitational pull of 10 N then its weight would
    be 10 N.

13
MW/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 5 N its mass is 20.

14
G w/m
  • This formula means that an objects gravitational
    pull is equal to its weight divided by its mass.
  • For example if a car has a weight of 100 N and a
    mass of 10 N its gravitational pull is 10 N.
