1
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
