cuvilinear n t coordinate systems example
If you're given the parametric equations describing the path of a particle. How do you find out the accelerations in the normal and tangential direction? Find the velocity and you know the tangential direction. Find the acceleration and...

Curvilinear motion example 2
What is the magnitude of the acceleration of a ball traveling around a circular path if it's constrained to have a constant vertical velocity? Always start these problems by doing a velocity analysis, then finish it by doing an...

Acceleration Vector Summary
Acceleration is a vector that describes the rate of change of velocity of a particle. Part of the acceleration of the particle will be tangential to the path, the rest will be normal to the path. The acceleration of the particle is...

Relative motion (with rotating axes) Summary
The equations for NON rotating reference axes are:
Va = Vb + Va/b
and
a_a = a
_b + a_a/b
But these equations are only true if the relative axes are not rotating. If the relative frame of reference xy is...
Va = Vb + Va/b
and
a_a = a
_b + a_a/b
But these equations are only true if the relative axes are not rotating. If the relative frame of reference xy is...

polar equation of motion
Here I derive the most generic equations of motion (position, velocity & acceleration) for a continuous curve. The calculus is pretty involved so I definitely recommend you hit up your math textbook first!

Bozeman Science: Newton's Second Law
In the following video Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a...
