## What direction is the angular momentum of your bicycle wheels as you ride forward?

When you are riding a bike forward, the right hand rule gives the direction of angular momentum to be to **the left, perpendicular to the wheel**.

## What direction is angular momentum in?

The direction of angular velocity and angular momentum are **perpendicular to the plane of rotation**. Using the right hand rule, the direction of both angular velocity and angular momentum is defined as the direction in which the thumb of your right hand points when you curl your fingers in the direction of rotation.

## When you ride a car in what direction is the angular velocity of the wheels?

In fact, the only real choice for its direction is **perpendicular to the wheel**. points along the axle of a wheel (as you can see in the figure). Angular velocity points in a direction perpendicular to the wheel. Because the angular velocity vector points the way it does, it has no component along the wheel.

## What is the direction of the angular velocity vector of your wheels?

The direction of the angular velocity vector is **parallel to the axis of the wheel** – so along the North South direction. The right hand rule shows that the ω vector points to the left of Mr. Foster.

## Under what conditions is angular momentum conserved?

Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved **when the net torque is zero**.

## What is required to change the angular momentum of a system?

Angular momentum depends on the distribution of mass, whereas linear momentum depends on the total mass. What is the law of inertia for rotating systems in terms of angular momentum? … Her **angular momentum does not change**.

## Is angular momentum parallel to angular velocity?

Thus, in general, the angular momentum vector of a rotating body **is not parallel to its angular velocity** vector. … We conclude that when a rigid object rotates about one of its principal axes then its angular momentum is parallel to its angular velocity, but not, in general, otherwise.

## Is Omega angular velocity?

**Angular velocity** is usually represented by the symbol omega (ω, sometimes Ω). By convention, positive angular velocity indicates counter-clockwise rotation, while negative is clockwise. … The orientation of angular velocity is conventionally specified by the right-hand rule.

## What is tangential acceleration formula?

The tangential acceleration **= radius of the rotation * its angular acceleration**. It is always measured in radian per second square. Its dimensional formula is [T^{–}^{2}]. … When an object makes a circular motion, it experiences both tangential and centripetal acceleration.
