What are the key differences between linear velocity () and angular velocity ()?
Linear Velocity (): The rate of change of linear position, depends on radius. | Angular Velocity (): The rate of change of angular position, uniform in a rigid system.
What are the key differences between linear acceleration () and angular acceleration ()?
Linear Acceleration (): The rate of change of linear velocity, depends on radius. | Angular Acceleration (): 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 applying a constant tangential force to the edge of a disk?
It causes the disk to experience angular acceleration and thus rotate with increasing angular velocity.
What is the effect of increasing the radius on the linear velocity of a point on a rotating object, given a constant angular velocity?
The linear velocity of the point increases.
What is the effect of a non-zero angular acceleration?
The angular velocity of the object changes over time.
What is the effect of applying a torque to an object?
It causes the object to experience angular acceleration.
What happens to the tangential acceleration if the angular acceleration increases?
The tangential acceleration increases proportionally, given a constant radius.
Define angular displacement ().
Angular displacement is the angle through which a point or object has been rotated in a specified direction.
Define angular velocity ().
Angular velocity is the rate of change of angular displacement with respect to time.
Define angular acceleration ().
Angular acceleration is the rate of change of angular velocity with respect to time.
Define tangential acceleration ().
Tangential acceleration is the linear acceleration of a point on a rotating object, tangent to the circular path.
Define 'rolling without slipping'.
Rolling without slipping is a type of motion where a rotating object moves along a surface without sliding; the point of contact between the object and the surface is instantaneously at rest.
