The dynamics of Newtons Laws

• By Laura Hubbard

Magnetic force

• Magnetic forces, like electric forces, are very
  large in comparison to gravitational forces. In
  fact, magnetic forces are produced by electric
  charges.
• It relates to my life by if I fall and I hit
  someone they fall to.

3
Electric force

• Electric forces, on the other hand, can be very
  large. If one extra electron could be added to
  each of the atoms in the two tennis balls, the
  resulting electric force between then would be
  500,000,000,000,000,000,000 newtons. We could
  never put such a charge on the tennis balls. They
  would be forced apart long before the charge was
  completed.

4
Gravitational force

• Gravitational force is an extremely weak force on
  comparison to the other forces. If two tennis
  balls are held one meter apart, the gravitational
  force between them is only 0.000,000,000,01
  newtons.

5
Weak interaction and nuclear force

• Nuclear forces are much stronger than any of the
  other forces. The nuclear force holds the nucleus
  of an atom together in spite of the strong
  electric force of repulsion between its protons.
• Scientists believe that a 2nd force exists inside
  the nucleus. This is called the weak interaction
  force. It is believed to be the force that causes
  some atoms to break apart.
• It is to small to see.

6
Newtons first law

• The first law says that an object at rest tends
  to stay at rest , and a object in motion tends to
  stay in motion.
• If I am sitting on the couch I am not probably
  not getting up unless my mom tells me to.

7
Newtons 2nd law

• The second law says that the acceleration of an
  object produced by a net (total) applied force is
  directly related to the magnitude of the force,
  the same direction as the force, and inversely
  related to the mass of the object (inverse is a
  value that is one over another number the
  inverse of 2 is ½).

8
Newtons third law

• The third law says that for every action (force)
  there is an equal and opposite reaction (force).
• If I hit the wall with my bike I will fall the
  bike.

9
F MxA

• To find force you have to take mass then you
  times it by acceleration.

10
M F/A

• To find mass u have to take force and divide it
  by area.

11
A F/M

• To find area u have to take force and divide it
  mass.

12
W MxG

• To find weight u take mass and u times it by
  gravity.

13
M W/G

• To find mass u have to take weight and divide it
  by gravity.

14
G W/M

• To find gravitation pull u take weight and I
  divide it by mass.
