Title: The Dynamics of Newton's Laws By: D Sparks


1
The Dynamics of Newtons Laws
  • By Dalton Sparks

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 a part.

6
Newtons first law.
  • Newtons first law of motion states that an
    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 and
    gravity pulls it down.

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 kick back because its a form of
    recoil.

9
FMA
  • This formula means that force is equal to mass
    multiplied by acceleration.
  • That means that if a car has a mass of 1,000 N
    and it is accelerating by 20N its force would be
    20,000.

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
    2000N and an acceleration of 40N its mass would
    be 500.

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 100N and a
    mass of 10N its acceleration would be 10N.

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 10N then its weight would
    be 10N.

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 100N and has a
    gravitational pull of 5 N its mass is 20N.

14
GW/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 100N and a
    mass of 10N its gravitational pull is 10N
