Dynamics of Newtons Laws

1
The Dynamics of Newtons Laws

• By Graham Shepherd

2
Magnetic Force

• Very large in comparison to gravitational forces.
  Magnetic forces are produced by moving electric
  charges.

3
Electric Force

• The force that appears when you push something
  with your hand is an electric force. The he
  electric force of repulsion develops at the
  electrons of the hand are brought close to the
  electrons of an object.

4
Gravitational force

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

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.

6
Newtons 1st Law

• An object at rest will stay at rest unless acted
  upon by an outside force.
• An example of this law is if you roll an tennis
  ball on the floor it wont stop until someone
  stops it

7
Newtons 2nd Law

• An unbalanced force causes acceleration
• If two cars are going 30 mph and they collide
  into each other the car with the smaller mass
  will have more damage to it

8
Newtons 3rd Law

• A single force can never exist. Every force is
  accompanied by an equal and opposite force
• An example would be a charged body repels another
  body.

9
FMA

• Force equals mass tomes 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 would be if you have an engine that
  can provide a force of 5.6 newtons, place the
  engine on a cart so of accelerates at 3.5/s/s.

11
AF/M

• Accelerationforce 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 mass times gravity
• Example- if your weight is 48 then your mass
  could be 24 and your gravity could be 2

13
MW/G

• Mass weight divided by gravity
• Example-if your cat has a mass of 24, the weight
  could be 72 and the gravity 3.

14
GW/M

• Gravity weight divided by mass
• An example could be an airplane could have the
  gravity of 100, weight of 200 and mass of 2.
