What is the effect of applying a constant torque to an object?
It causes the object to experience angular acceleration.
What happens when angular acceleration is zero?
The angular velocity remains constant.
What is the effect of increasing the radius on linear speed, given a constant angular velocity?
The linear speed increases (v = rω).
What happens if the angular velocity is constant?
Angular displacement increases linearly with time.
What is the effect of a negative angular acceleration?
It causes a decrease in angular velocity.
What is the difference between angular velocity (ω) and angular acceleration (α)?
Angular Velocity (ω): Rate of change of angular displacement. | Angular Acceleration (α): Rate of change of angular velocity.
Compare clockwise and counterclockwise direction in rotational motion.
Clockwise (CW): Usually considered the negative direction. | Counterclockwise (CCW): Usually considered the positive direction.
Compare angular displacement and arc length.
Angular Displacement: Angle through which an object has rotated. | Arc Length: Distance traveled along the circular path.
Compare linear velocity and angular velocity.
Linear Velocity: Velocity of a point on a rotating object (m/s). | Angular Velocity: Rate of rotation (rad/s).
Compare linear acceleration and angular acceleration.
Linear Acceleration: Rate of change of linear velocity (m/s²). | Angular Acceleration: Rate of change of angular velocity (rad/s²).
What is the difference between angular velocity and angular acceleration?
Angular Velocity: Rate of change of angular displacement. | Angular Acceleration: Rate of change of angular velocity.
What is the difference between clockwise and counterclockwise direction in rotational motion?
Counterclockwise (CCW): Usually considered the positive direction. | Clockwise (CW): Usually considered the negative direction.
Compare linear and angular displacement.
Linear Displacement: Change in position along a straight line (meters). | Angular Displacement: Change in angular position (radians).
Compare linear and angular velocity.
Linear Velocity: Rate of change of linear displacement (m/s). | Angular Velocity: Rate of change of angular displacement (rad/s).
Compare linear and angular acceleration.
Linear Acceleration: Rate of change of linear velocity (m/s²). | Angular Acceleration: Rate of change of angular velocity (rad/s²).
