The kinematics of rotational motion describes the relationships between the angle of rotation, angular velocity, angular acceleration, and time. It only describes motion—it does not include any forces or masses that may affect rotation (these are part of dynamics).

For an object rotating counterclockwise, the angular velocity points toward you along the axis of rotation. Angular velocity (ω) is the angular version of linear velocity v. Tangential velocity is the instantaneous linear velocity of an object in rotational motion.
Vector angular velocity. For an object rotating about an axis, every point on the object has the same angular velocity. The tangential velocity of any point is proportional to its distance from the axis of rotation. Angular velocity has the units rad/s.
20 lut 2022 · Observe the kinematics of rotational motion. Derive rotational kinematic equations. Evaluate problem solving strategies for rotational kinematics. Just by using our intuition, we can begin to see how rotational quantities like θ, ω θ, ω and α α are related to one another.
The Rotational Motion Interactive allows a learner to explore the relationship between the angular velocity and the linear velocity for a couple of bugs on a rotating disk. The rotational velocity of the disk and the location of the bugs upon the disk can be varied.
20 lut 2022 · Dynamics for rotational motion is completely analogous to linear or translational dynamics. Dynamics is concerned with force and mass and their effects on motion. For rotational motion, we will find direct analogs to force and mass that behave just as we would expect from our earlier experiences.
The kinematics of rotational motion describes the relationships among rotation angle, angular velocity, angular acceleration, and time. Let us start by finding an equation relating ω ω , α α , and t t .
