The dynamics of Newton's Laws

• By Landen Holder

2
Magnetic force

• Magnetic forces are produced by moving electrical
  forces
• Magnetic and electrical forces are very close
  related

3
Electric force

• An electric force is produced when you push
  something
• The electric force of repulsion develops when the
  electrons in your hand are brought close to the
  electrons of an object

4
Gravitational force

• Gravitational force is extremely weak compared
  tot the other forces
• Gravitational force is when an object is
  attracted to another larger object

5
Weak interaction and nuclear force

• Nuclear forces are much stronger than any of the
  other forces
• This force holds together the nucleus of an atom
• Scientists believe that a force exists inside the
  nucleus of atoms called weak interaction
• It is believed to be the force that causes atoms
  to break apart

6
Newton's first law

• Newton's first law states that an object in
  motion will stay in motion and an object at rest
  will stay at rest unless acted upon by an outside
  force
• Throw a baseball and someone catches it to stop it

7
Newton's second law

• A force on an object will move the object in the
  direction of the force
• An example of this is a person hitting a golf
  ball with a golf club and the ball traveling in
  the direction of the club

8
Newton's third law

• Every action has an equal and opposite reaction
• An example of this would be a rocket taking off.
  The force is the blast of ignited fuel and the
  reaction is the rocket shooting upwards

9
F M x A

• This formula means that force equals the mass
  times the acceleration of an object
• This means that if a car has a mass of 1000 N and
  it is accelerating by 20 N its force would be
  20,000 N

10
M F / A

• This formula means that mass is equal to force of
  an object divided by its acceleration
• An example is a football with a force of 50 N and
  its traveling at 10 N its mass is 5 N

11
A F / M

• This formula means that an objects acceleration
  can be found by dividing its force by its mass
• An example is if a car has a force of 600 N and
  its mass is 200 N its acceleration is 3 N

12
W M x G

• This means that weight is equal to the mass of an
  object multiplied by the gravitational force
  acting on it
• For example is a vehicles mass is 25 N and their
  gravitational pull from the Earth is 30 N their
  weight is 750 N

13
M W / G

• This means that an objects mass is equal to the
  weight of an object divided by its gravitational
  pull
• For example if a car weighs 100 N and has a
  gravitational pull of 10 N its mass is 10 N

14
G W / M

• This formula means that the gravitational pull on
  an object is equal to its weight divided by its
  mass
• For example if a car has a weight of 25 N and its
  mass is 5 N its gravitational pull on the car is
  5 N
