Newtons Laws of Motion

• Conceptual Physics

2
Beginning Terms

• Force(F) a push or a pull, measured in Newtons
  (N), forces are vectors
• Friction(f) the force between two objects that
  are in contact
• Coefficient of friction(µ) a number that shows
  how big the force of friction will be between two
  objects
• Inertia the property of matter that tends to
  resist a change in its motion

3
More Terms

• Mass(m) the amount of matter in an object,
  measured in kilograms(kg)
• Weight(w) the amount of force gravity exerts on
  an objects mass, measured in Newtons wmg
• Net Force the total force acting on an object,
  it is an objects net force that causes a change
  in its motion

4
Even More Terms

• Equilibrium when an objects net force is zero,
  itll be sitting still or have constant velocity
• Normal Force(FN) the force perpendicular to the
  surface an object sits on , also called the
  support force
• Pressure(P) the amount of force per unit area,
  measured in Pascals (Pa), formula is PF/A where
  A is area

5
Yes, Even More Terms

• Terminal Velocity the maximum velocity a free
  falling object reaches when its weight finally
  equals its air resistance
• Action/Reaction Pair a pair of equal and
  opposite forces acting on the same object

Newtons First Law of Motion

• Objects at rest tend to remain at rest and
  objects in motion tend to remain in motion unless
  acted upon by an outside force.
• This is also called the Law of Inertia since it
  is an objects inertia that causes this law to
  happen.

7
Newtons Second Law of Motion

• The acceleration of an object is directly
  proportional to the force acting upon the object,
  or Fma.

8
Newtons Third Law of Motion

• For every action there is an equal and opposite
  reaction.
