All forces share certain common characteristics when considered by observers in inertial reference frames. (A frame of reference in which a body remains at rest or moves with constant linear velocity unless acted upon by forces)

An observer in a reference frame can describe the motion of an object using such quantities as **position, displacement, distance, velocity, speed, **and **acceleration.**

For rotational motion we define these quantities in terms of __ radians__ instead of meters.

Imagine taking the radius of a circle and wrap it around the circumference. It will create an angle whose arc length is equal to the radius. The angle that is created is **1 Radian**.

An angle of 𝜋 radians would have an arc length of half the circumference and a full circumference would have an angle of 2𝜋 radians.

**Angular Displacement** - represented by the angle 𝜃 in radians

**Angular Velocity** - change in angular displacement over time. It can also be calculated from the frequency of the object’s rotation.

**Angular Acceleration** - change in angular velocity over time.

**All of the linear terms can be related to their rotational term by the following equations (r = radius of the circle). These are NOT on the reference table.**

In Kinematics there are four major equations you must understand to begin calculations. They relate **acceleration, displacement, initial and final velocity, **and **time **together**.**

**Variable Interpretation:** Δ𝜃 is angular displacement in radians, 𝜔 is final angular velocity in radians/second, 𝜔o is initial angular velocity in radians/second, t is time in seconds, and 𝛼 is acceleration in rad/s^2.

⟶ In order to solve for a variable without having all four other quantities known, we look at the ‘Variable Missing’ column to pick the equation that best suits our question.
