The dynamics of Newtons laws

• Dynamics are the study of forces that cause
  motion.
• By Kalie Ginter

2
Magnetic forces

• Magnetic forces are produced by moving electric
  charges
• Positive to negative attracts
• Positive to positive repels
• Negative to negative repels
• Ex On a magnetic bullet train there is a
  positive magnet on the back and positive magnets
  on the track, which repels and moves the train.

3
Electric forces

• The forces 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 object come in contact
• Ex When you high five somebody its a electric
  force.

4
Gravitational forces

• Gravitational forces is a extremely weak for
  compared to the other forces.
• Ex two tennis balls are held 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 interaction and nuclear force

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

6
Newton's first law

• An object at rest must stay at rest until a
  forces is acted upon it.
• An object in motion will stay in motion till a
  forces is acted upon it.
• Ex when your in car you will keep going until a
  force such as the break is acted upon it.

7
Newtons second law

• If you exert the same force on two objects of
  different mass, you will get different
  accelerations.
• Ex a tennis ball and a ping pong ball are both
  dropped from the top of a building ones
  acceleration was be faster and one will be
  slower.

8
Newtons third law

• For every action there is an equal and opposite
  reaction.
• Ex you find it hard to walk on a slippery
  surface because the only way you can walk forward
  is for your foot to push backward on the surface
  of the ground. Through friction, the ground is
  essentially pushing back against the force of
  your step.

9
FMxA

• Force equals mass times acceleration
• Ex 10020x5

10
MF/A

• Mass equals force divided by acceleration
• Ex11585/5

11
AM/F

• Acceleration equals mass divide by force
• Ex7515/5

12
WMxG

• Weight equals mass times gravity
• Ex 124x3

13
MW/G

• Mass equals weight divide by gravity
• Ex 459/5

14
GW/M

• Gravity equals weight times mass
• Ex 55/1
