And some talk about units, orders of magnitude, sig figs etc. . .

The Gravitational Field
A gravitational field exists at every point in space When a particle of mass m is placed at a r g point where the gravitational fieldris , the r F particle experiences a forceg = mg The field exerts a
Motion of a Top
The only external forces acting on the top are the normal force and the gravitational force The direction of the angular momentum is along the axis of symmetry The right-hand rule indicates that the torque is in the xy plane

Newtons 3rd Law
Oh and Gravitational Force and Weight.
Gravitational Force and Weight
Weight is a Force, it is NOT the same as mass! The Force due to gravity is an exception to the statement that mass times acceleration does not constitute a nameable for
The Laws of Motion!
Force (Not The Force, But Almost As Cool)!
What are forces?
Forces are how objects interact with one another. Forces can cause acceleration.
What are forces mathematically?
Scalars or Vectors
Adding Forces!

Another Special Case . . . You know my mom always told me I was special too!
Just a thought . . .
What does it mean for velocity to be the derivative (a.k.a. slope) of position? Specifically what does it mean about the direction of

Question to ponder
In two dimensions, a non-zero acceleration can A) Cause a change in the magnitude but not direction of velocity. B) Cause a cha
Vectors!
What are they and how do we work with them?
Vectors Vs. Scalars!
Unlike in real estate, with vectors it is not so much Location, Location, Location, but Direction, Direction, Direction! Vectors have a length or magnitude and a direction. Scalars
Yeah Motion!
(A. K. A. Kinematics)
What is it?
Kinematics is the study of motion! Including: -Translation -Rotation -And Vibration
