Question

plz tell me the definition of these terms:-- a) Impulse b) Angular speed c) Linear monentum

Answer 1

Angular velocity, also called rotational velocity, is a quantitative expression of the amount of rotation that a spinning object undergoes per unit time. It is a vector quantity, consisting of an angular speed component and either of two defined directions or senses.

 Impulse is a vector quantity defined as the product of the force acting on a body and the time interval during which the force is exerted. ... The unit of impulse is the same as the unit of momentum, kg.

Linear momentum is a vector quantity defined as the product of an object's mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called “momentum” for short: Note that a body's momentum is always in the same direction as its velocity vector. The units of momentum are kg. · m/s
