# What is the difference between tangential velocity and angular velocity?

Angular velocity is defined as the rate of change of an angle, while tangential velocity as the rate of change of displacement.

Angular velocity is a vector with a direction and angular speed is a scalar with no direction.

Tangential acceleration is acceleration in the direction of travel, i.e. tangent to the instantaneous velocity. Centripetal acceleration is perpendicular or normal to that, specifically, in the direction of the acceleration, i.e. towards the center of the circle of travel. Angular acceleration is anything in between, or outside of those two definition, i.e. not tangent and not normal.

what is the relationship between the angular velocity of gear 1 and the angular velocity of gear 2?

Answer Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation. Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.

There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.

momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel

If there is a rotation, "angular velocity" and "angular frequency" is the same thing. However, "angular frequency" can also refer to situations where there is no rotation.

Orbital Velocity is calculated in m/s where as angular velocity is calculated in rad/s.. Answer is very clear.. angular velocity is calculated when body is rotating around a axis and a reference point is needed to calculate it.. where as orbital velocity is calculated when body is moving around a bado in circular path, nt around itself... e.g. Earth rotates around so it have angular velocity .. it also rotates around sun in orbit so it has Orbital velocity also :)

What is the difference between a satellite and a probe with regard to orbital velocity and escape velocity

By radial force, we can assume you mean centripetal force Centripetal force = (Mass)(Radius)(Angular velocity)2

linear velocity is a change of speed in a linear fashion. Angular speed is the rate of change of angle with respect to time. These two are convertible in a case of a circle motion. the lenght of an arc is l = RO. where O is the angle. hence v= l/t and therefore v=RA where A = O/t.

The difference is in the direction of the acceleration. Tangential acceleration is in the direction of movement. Radial acceleration is at right angles to it (towards, or away from, the center of a circle for example).

The time, T , it takes for an object to go thru one comblete rotation of 360 degrees or 2pi radians is its "period." The rate at which it completes the rotation is its "angular velocity." The rate is the angle (in radians) divided by the time. So , Angular Velocity = 2 pi / T.

muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.

The technical difference is that speed has no direction but velocity has one.

The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.

angular velocity = w = radians /second There are 2 piradians in one complete cycle w = 2 pi frequency frequency = w/2 pi =cycles per second
