The Dynamics of Newtons Laws

1
The dynamics of Newton's laws

• By Morgan Stephens

2
dynamics

• Is this study of force which causes motion.

3
Gravitational force

• the force of attraction between all masses in the
  universe especially the attraction of the
  earth's mass for bodies near its surface.

4
Electric force

• An attractive or repulsive electrostatic force
  described by Coulomb's law.

5
Magnetic force

• A force that exists between two electrically
  charged moving particles.

6
nuclear force

• This force is never really observed because it
  only exist inside the nucleus.

7
Weak interactions

• This force is also rarely observed because it is
  also located inside the nucleus and cant be
  observed as easily.

8
Newton's 1st law of motion

• that a body at rest will remain at rest, and a
  body in motion will remain in motion with a
  constant velocity, unless acted upon by a force.
• An example of this is someone on a roller coaster.

9
Newton's 2nd law

• that a force acting on a body is equal to the
  acceleration of that body times its mass.
  Expressed mathematically, F ma, where F is the
  force in Newton's, m is the mass of the body in
  kilograms, and a is the acceleration in meters
  per second per second.
• An example of this is two cars hitting each other.

10
Newton's 3rd law

• Every action there is an equal and opposite
  reaction. Thus, if one body exerts a force F on a
  second body, the first body also undergoes a
  force of the same strength but in the opposite
  direction. This law lies behind the design of
  rocket propulsion, in which matter forced out of
  a burner at high speeds creates an equal force
  driving the rocket.
• An example of this is two people pushing on each
  other.

The formulas of these laws
12
F M x a

• This formula would be used to get the force. You
  would multiply mass by acceleration, and then get
  the total amount of force that is applied.
• For example, if the mass was 15, and the
  acceleration was 25, the force would be 375.

13
MF/A

• To solve this formula you would have to divide
  force by acceleration. You are trying to get how
  much mass is in this object.
• For example, of the force was 25, and the
  acceleration was 5, the mass would also be 5.

14
AF/M

• To solve this formula would will have to divide
  force by mass. You are trying to figure out how
  much acceleration this object has.
• For example, if the force was 30, and the mass
  was 10, the acceleration would be 3.

15
WMxG

• To solve this formula you would have to multiply
  mass by gravity. You are trying to figure out how
  much this object weighs.
• For example, if the mass was 15, and the gravity
  was 3, the weight would be 45.

16
MW/G

• To solve this formula you would have to divide
  weight by gravity. You need to find the mass of
  this object.
• For example, if the weight was 20 and the gravity
  was 4, the mass would be 5.

17
GW/M

• To solve this formula you will have to divide
  weight by mass. You are getting how much gravity
  this object has.
• For example, if the weight was 50, and the mass
  was 10, the gravity would be 5.

Newton's laws pertain to history

• The 1st law relates to a tool the Greeks
  invented. A catapult.
• The 2nd law relates to the ox drawn plow.
• The 3rd law relates to ice skating.
