Title: The Dynamics of Newtons Laws


1
The Dynamics of Newtons Laws.
  • By Delaney Bromagen

2
Magnetic Force
  • Magnetic forces are very large in comparison to
    gravitational forces. They are produced by moving
    electric charges. Electric and magnetic forces
    are closely related.

3
Electric Force
  • The force that appears when you push or pull
    something. Repulsion develops as the electrons of
    the hand are brought close to the electrons of an
    object.

4
Gravitational Force
  • Is an extremely weak force compared to the other
    forces. If two tennis balls are held one meter
    apart, the gravitational force between them is
    only .00000000001.

5
Weak Interaction and Nuclear Force
  • Nuclear forces are much stronger then any other
    forces. It holds the nucleus of an atom together.
    A second force also is inside the nucleus. It is
    the weak interaction because some of the atoms
    are known to break apart.

6
Newtons First Law and Real Life Example
  • Newtons first law of motion is An object at
    rest will stay in rest, unless acted upon by an
    outside force. An example could be if you roll a
    tennis ball on the floor it will keep going until
    someone or something stops it.

7
Newtons Second Law and Example
  • An unbalanced force causes acceleration. For
    example, two cars, one car at rest while the
    other collides into it fast when driving in a
    straight line. The car at rest is acted upon by
    the moving car.

8
Newtons Third Law and Real Life Example.
  • This is the law of action and reaction. States
    that every force is accompanied by an equal and
    opposite force.
  • An example could be a charged body repels another
    body.

9
FMA
  • Force equals mass times acceleration
  • An example could be the acceleration of a 2kg
    brick thrown with a force of 4 newtons.

10
MF/A
  • Motion- Force and acceleration.
  • An example could be if you have an engine that
    can provide a force of 5.6 newtons, and place the
    engine on a cart so it accelerates at 3.5/s/s.

11
AF/M
  • Acceleration force divided by mass
  • Example- if the acceleration of a hammer is 6,
    then the force could be 36 and the mass would be
    6.

12
WMG
  • Weight equals mass times gravity.
  • An example could be if your weight is 48 then
    your mass could be 24 and your gravity could be 2.

13
MW/G
  • Mass equals weight divided by gravity.
  • For example, if your cat has a mass of 24, the
    weight could be 72 and the gravity 3.

14
GW/M
  • Gravity equals weight divided by mass. An
    airplane could have the gravity of 100, weight of
    200, and mass of 2.
