The dynamics of Newtons Laws

• By Afton Ginter and Joe Garris

2
Magnetic force

• Magnetic forces, like electric forces, are very
  large in comparison to gravitational forces. In
  fact, magnetic forces are produced by moving
  electric charges.
• Example magnet

3
Electric force

• The force that appears when you push on something
  with your hand is an electric force. This
  electric force of repulsion develops as the
  electrons of the hand are brought closer to the
  electrons of an object.
• Example door

4
Gravitational forces

• Gravitational force is an extremely weak force in
  comparison to the other forces. If two tennis
  balls are held one meter apart, the gravitational
  force between them is only 0.00000000001 newton.
• Example gravity

5
Weak interactions and nuclear force

• Nuclear forces are much stronger the any other
  forces. The nuclear force holds the nucleus of an
  atom together in spite of the strong electric
  force of repulsion between its protons. Sometimes
  nuclei of atoms change by gaining or losing
  particles.
• Example nucleus

6
Newtons First Law

• The first law , says that an object at rest tends
  to stay at rest, and an object in motion tends to
  stay in motion, with the same direction and
  speed. Motion cannot change without an unbalanced
  force acting.
• Example Soccer Ball.

7
Newtons Second Law

• The second law says the acceleration of an object
  produced by a net applied force is directly
  related to the magnitude of the force, the same
  direction of the force, and inversely related to
  the mass of an object.
• Example person

8
F MxA

• FMxA means force, mass, and acceleration.
• Example Ball

9
MF/A

• MF/A means mass, force, and acceleration.
• Example rocket

10
MF/A

• MF/A means mass, force, and acceleration.
• Balloon

11
AF/M

• AF/M means acceleration, force, and mass.
• Example plane

12
WMxG

• WMxG means weight, mass, and gravity.
• Example sun

13
MW/G

• MW/G means mass, weight, and gravity.
• Example moon

14
GW/M

• GW/M means gravity, weight, and mass.
• Example planets
