difference between angular velocity and linear velocity |
| Answer» \t\xa0Linear VelocityAngular VelocityDefinitionWe define the linear velocity as the rate of change of the linear displacement.We define the angular velocity as the rate of change of angular displacement.Key DifferencesIn a circular motion, the linear velocity of a particle is along the circumference of a circle.\xa0It is different at different points on the circle.The angular velocity of a particle is along the axis of a circle.It remains the same throughout the circular motion.SymbolThe symbol for the linear velocity is v.The symbol for angular velocity is a Greek letter, i.e., ω (pronounced as omega).Formulav = ΔSΔt = 2πrtω = ΔθΔt = 2πrtQuantityIt is a vector quantity that implies it has both magnitude & direction.It is an axial vector. Its because the direction of the displacement of the particle is along the axis of the circle.Measuring UnitWe measure the linear velocity in m/s.We measure the angular velocity in both degrees and radians. A degree is a dimensionless unit. Radian is an SI unit.Real-life ExampleIf your office is at 150 km distance from your home, then your car will acquire a linear velocity.\xa0\t | |
