The Dynamics of Newtons Laws

• By Hayden Holley

2
Magnetic Force

• Magnetic forces are produced by moving electric
  charges
• Positive to negative attract
• Negative to negative repels
• Positive to positive repels
• Ex On a rollercoaster there is a positive magnet
  on the car and there is a negative magnet on the
  track which causes it to attract.

3
Electric Force

• The force that appears when you push on something
  with your hands.
• This appears when the electrons of the hand is
  brought close to the electrons of an object.
• When two objects come in contact.
• Ex When you high five somebody its an electronic
  force.

4
Gravitational Force

• Gravitational forces is an extremely week for
  compared to the other forces.
• Ex Two tennis balls are held to one meter
  apart, the gravitational force between them are
  0.00000000001 newton's the forces in the other
  hand can be way great such as 500 000 000 000 000
  000 000 newton's.

5
Weak interactions and nuclear force

• Nuclear forces are much stronger than any other
  force.
• Weak interactions is the force that cause some
  atoms to break down.
• But neither of them are observable because their
  in the nucleus.

6
Newtons First Law

• An object at rest must stay at rest until a force
  is acted upon it.
• An object in motion will stay in motion until a
  force is acted upon it.
• Ex When your in a car, it will keep moving until
  a force is acted upon it such as the breaks.

7
Newtons Second Law.

• If you exert the same force on two objects of
  different mass, you will get different
  accelerations.
• Ex A soccer ball and a basketball are dropped
  from a building, the acceleration of one of the
  balls is going to be faster than the other.

8
Newtons Third Law

• For every action there is an equal and opposite
  reaction.
• Ex If you throw a heavy ball or block away from
  your body, the force exerted will push back on
  you, possibly pushing you backward onto the
  ground.

9
F M x A

• Force equals mass times acceleration
• F force
• M mass
• A acceleration
• Ex 50 10 x 5

10
M F/A

• Mass equals force divided by acceleration
• M mass
• F force
• A acceleration
• Ex 4 3/12

11
A F/M

• Acceleration equals force divided by mass
• A acceleration
• F force
• M mass
• Ex 20 5/100

12
W M x G

• Weight equals mass times gravity
• W weight
• M mass
• G gravity
• Ex 12 4 x 3

13
M W/G

• Mass equals weight divided by gravity
• M mass
• W weight
• G gravity
• Ex 5 10/2

14
G W/M

• Gravity equals weight divided by mass
• G gravity
• W weight
• M mass
• Ex 5 4/20
