Biomech. Week 2, Day 1-Lecture on Angular Motion and Gymnastics

These flashcards cover key concepts discussed in the lecture about angular motion and apply them to the gymnastics move known as the giant circle.

What is the primary focus of today's session?

Calculating angular variables linked to the gymnastics move called the giant circle.

What are the names of the documents found in the Moodle site for this unit?

Equations document, worksheet describing the session, and an Excel spreadsheet.

What is angular velocity?

The rate of change of the angle over time, typically expressed in degrees per second or radians per second.

How do we calculate angular acceleration?

By using the change in angular velocity over time.

What is the tangential velocity?

The linear velocity of a point at a radius from the center of motion, always directed at a right angle to the radius.

What happens to angular velocity while the gymnast performs the giant circle?

It increases as she swings down and decreases as she swings back up.

What is centripetal acceleration?

Acceleration directed towards the center of a circular path, necessary for an object to maintain circular motion.

How is the tangential velocity related to angular velocity?

Tangential velocity is calculated by multiplying the radius by the angular velocity.

What influence does changing body position have on a gymnast during the giant circle?

It affects the radius and subsequently the angular and tangential velocities while in motion.

What is the significance of the handstand position in the context of angular motion?

It's the starting point at which the gymnast begins the circular motion, indicating the initial angle.
