What is the difference between linear and angular displacement?

Linear displacement: distance traveled along a straight line. Angular displacement: angle through which an object has rotated.

What is the difference between linear and angular velocity?

Linear velocity: rate of change of linear displacement. Angular velocity: rate of change of angular displacement.

What is the difference between linear and tangential acceleration?

Linear acceleration: rate of change of velocity in a straight line. Tangential acceleration: rate of change of tangential velocity of a rotating object.

Compare angular velocity at different points in a rigid rotating system.

All points in a rigid rotating system share the same angular velocity, regardless of their distance from the axis of rotation.

Compare tangential velocity at different points in a rigid rotating system.

Points further from the axis of rotation in a rigid rotating system have greater tangential velocity.

What are the key differences between linear velocity (vvv) and angular velocity (ω\omegaω)?

Linear Velocity (vvv): The rate of change of linear position, depends on radius. | Angular Velocity (ω\omegaω): The rate of change of angular position, uniform in a rigid system.

What are the key differences between linear acceleration (aaa) and angular acceleration (α\alphaα)?

Linear Acceleration (aaa): The rate of change of linear velocity, depends on radius. | Angular Acceleration (α\alphaα): The rate of change of angular velocity, uniform in a rigid system.

Compare and contrast angular velocity and tangential velocity.

Angular Velocity: Rate at which an object rotates (rad/s), constant for all points on a rigid rotating object. Tangential Velocity: Linear speed of a point on a rotating object (m/s), depends on the radius.

Compare and contrast angular acceleration and tangential acceleration.

Angular Acceleration: Rate at which angular velocity changes (rad/s²), constant for all points on a rigid rotating object. Tangential Acceleration: Linear acceleration of a point on a rotating object (m/s²), depends on the radius.

What is the effect of increasing angular velocity on linear velocity?

Increasing angular velocity increases the linear velocity of a point on a rotating object, according to the relationship v=rωv = r\omegav=rω.

What is the effect of increasing angular acceleration on tangential acceleration?

Increasing angular acceleration increases the tangential acceleration of a point on a rotating object, according to the relationship aT=rαa_T = r\alphaaT​=rα.

What is the effect of increasing the radius on linear velocity, given a constant angular velocity?

Increasing the radius increases the linear velocity of a point on a rotating object, given a constant angular velocity, according to the relationship v=rωv = r\omegav=rω.

What is the effect of applying a torque to a rigid object?

Applying a torque to a rigid object causes it to experience angular acceleration.

What is the effect of a net force applied to the center of mass of an object?

A net force applied to the center of mass of an object causes linear acceleration.
