A child swings her 40 cm (0.4 meter) long, straight arm around her shoulder joint at a 13 rad/s angular velocity. So, her hand is moving at 5.2 m/s every second.

<h3>What does angular velocity mean?</h3>

angular velocity is the speed where an object rotates or revolves around an axis or alters the angle between two bodies. The angle between a line solely on a single body and a line on the other in the illustration serves as a representation of this displacement.

<h3>In what way does angular velocity rise?</h3>

The angular velocity increases with increasing rotational angle over a certain period of time. Degrees per second (o/s), radians per second (rad/s), or revolutions per minute (rpm), if appropriate, are the units for angular velocity. An element of a vector is angular velocity.

The speed on a car speedometer. Is it speed or velocity? Explain Why
Sliva [168]
Velocity is a speed AND a direction.
When you turn a corner, or go around a curve in the road, your
direction changes, but the reading on the dial doesn't change.
So it can't be showing velocity.  It must be showing only speed.
That's probably a big part of the reason why it's called a speedometer
and not a velocimeter.

Grace [21]

The law of energy conservation states that energy cannot be created or destroyed, so choices B to D are immediately invalid. Choice A can explain this occurrence: <u>A. Some of the energy is used to combat friction, and thus is transformed from mechanical energy to heat.</u>
