The Dynamics of Newtons Laws.

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.

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.
