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 .
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 .
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.
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 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.
