This document provides an overview of key concepts in mechanics and motion, including: - Definitions of speed, velocity, acceleration, and related formulas. Speed is rate of change in position, velocity includes direction of motion. - Discussion of different types of motion (constant, average, instantaneous speed) and forces (balanced, unbalanced). Newton's three laws of motion are introduced. - Explanations of concepts like inertia, friction, gravity, mass vs. weight, projectile motion, and circular/centripetal motion, with examples provided.

30. Acceleration Section 1.3

34. How to Calculate Acceleration?  means “change in”

37. What are some other ways to say that the car is accelerating?

112. Projectile Motion Notes 4.2

124. Circular Motion Notes 4.2

132. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force required for circular motion. As a bucket of water is tied to a string and spun in a circle, the force of tension acting upon the bucket provides the centripetal force required for circular motion. As a car makes a turn, the force of friction acting upon the turned wheels of the car provide the centripetal force required for circular motion.

133. Action and Reaction Notes 4.4

134. Without a centripetal force, an object in motion continues along a straight-line path. With a centripetal force, an object in motion will be accelerated and change its direction.
