Increasing angular acceleration increases the tangential acceleration of a point on a rotating object, according to the relationship .
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 .
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.
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.
Define angular displacement ().
The angle through which a point or line has been rotated in a specified direction.
Define angular velocity ().
The rate of change of angular displacement with respect to time.
Define angular acceleration ().
The rate of change of angular velocity with respect to time.
Define arc length ().
The distance along a curved path.
Define tangential acceleration ().
The component of acceleration of a point on a rotating object that is tangent to the circle of motion.
What is a 'rigid rotating system'?
A system that maintains its shape and size during rotation, where all points share the same angular velocity and angular acceleration.
