  • conventions - Unit of Angular velocity - Physics Stack Exchange
    The radian is the standard unit of angular measure Angular velocity is just the angle traversed by a particle or a body in unit time You may give it any sensible unit which should obviously denote the angle traversed per unit time Therefore you may use the unit deg s d e g s The unit rad s r a d s is commonly used because it is an SI unit and the relations like v = ωr v = ω r are
  • Why are the units of angular acceleration the same as that of angular . . .
    From dimensional analysis, this yields units of radians s Also by definition, angular acceleration is defined as the rate of change of angular velocity with respect to time, leading to the equation α = Δω Δt From dimensional analysis, Δω has units of rad s, so the units of α are rad s ∗ 1 s, leading to final units of rad s2
  • Components of Angular velocity - Physics Stack Exchange
    Angular velocity vector is defined as, →ω = ˆndθ dt where ˆn is an unit vector along the axis of rotation, and dθ dt is the angular rate at which the particle is turning about the axis of rotation See figure 1 Being a vector, →ω can be resolved into components: →ω = ωxˆi + ωyˆj + ωzˆk Question: What is the physical interpretation of ωx, ωy, and ωz, other than being the
  • homework and exercises - What are the dimensions of angular velocity . . .
    My friend said that angular velocity has dimensions of T − 1 Or equivalently, it's measured in rad s, and rad is dimensionless, leaving only the 1 s But I think that angular velocity should have the same units LT − 1 as translational velocity, because both of them are velocities Shouldn't the angular velocity be the distance traveled along the circumference per unit time? How could
  • newtonian mechanics - Why are angular velocity and angular frequency . . .
    This means the units of angular velocity and angular frequency are (meter second) meter or 1 second Rotational frequency is also measured in 1 s 1 s which in Hz However, angular frequency is different from ordinary frequency I am really confused as why it isn't measured in Hertz
  • Why is the time rate change of unit vector given by the angular . . .
    Why is the time rate change of unit vector given by the angular velocity vector crossed with the unit vector? Ask Question Asked 4 years, 8 months ago Modified 4 years, 8 months ago
  • How to derive the formula for angular velocity?
    Now, the angular velocity →ω is defined in two parts: its magnitude is given by the rate of change of angular displacement its direction is perpendicular to that of →r and → dr, as determined by the thumb-rule To relate the angular displacement dϕ to the position and displacement vectors, we make another construction
  • Is there any quantity unit that represent Mass $\\times$ Velocity . . .
    There is, in principle, no correlation between distance traveled and energy used, though there could be a correlation in some specific case E g , in car travel But, the need to supply energy for car travel arises from interactions between tires and pavement and, between a bulky body and viscous air It's not for any fundamental reason that only depends on mass and velocity
