Physics Review Flashcards

Flashcards covering key physics concepts and equations.

When analyzing the energy of a system, what must be accounted for?

The energy of each part of the system must be accounted for, as separate pieces

In a system, what is true of the systems velocity?

The velocity is the same throughout, and it can be factored out.

What is the equation for acceleration on an inclined, frictionless surface?

a = g * sin(theta)

What is the equation for static friction on an incline?

Ms * g * tan(theta)

What is the equation for acceleration down a rough incline?

a = g * sin(theta) - Mic * g * cos(theta)

State Newton's Three Laws of Motion.
