Question

A pair of scissors is being used to cut a string. Does each blade of the scissors have the same angular velocity (both magnitude and direction) at a given instant?

Answer 1

Each blade of the scissors does not have the same angular velocity (both magnitude and direction) at a given instant. Each blade has the same angular speed but have opposite direction.

Answer 2

A pair of scissors is being used to cut a string. Each blade of the scissors does not have the same angular velocity (both magnitude and direction) at a given instant. Each blade has the same angular speed but have opposite direction.

Step-by-step explanation:

A pair of scissors is being used to cut a string. Each blade of the scissors does not have the same angular velocity (both magnitude and direction) at a given instant. Each blade has the same angular speed but have opposite direction. The angular velocity is given by

ω= ∅/t

Both blades rotate around the same axis so they have same angular displacement and same speed or the magnitude of the angular velocity but the angular velocity is a vector quantity and it has different direction for the two blades.
