Why angular velocity is perpendicular to linear velocity?

It was pointed out that angular velocity is one of the operands of the vector product. From the relation, we can only conclude that angular velocity is perpendicular to linear velocity. We can see that this condition is fulfilled for any direction of velocity in the plane of motion.

Why velocity is perpendicular in circular motion?

“Uniform circular motion” means traveling in a circle with constant speed. As such, the velocity is changing in direction (toward the center) but not in magnitude. Hence the change in velocity (and thus the acceleration) points radially inward — i.e., perpendicular to the velocity.

Why is direction of angular velocity perpendicular to plane of circular motion?

Direction of angular velocity of a body is perpendicular to the plane of motion, because the velocity of the body is cross-product of angular velocity and the perpendicular distance between the axis of rotation of the body and the angular velocity vector.

How is circular motion different from linear motion?

Linear motion is also called rectilinear motion. It is a motion on a straight line in one-dimension. Circular motion is an object’s moving across a circle or movement across a circular direction.

What is the relation between linear and circular velocity?

Difference between Linear Velocity and Angular Velocity

	Linear Velocity
Definition	We define the linear velocity as the rate of change of the linear displacement.
Key Differences	In a circular motion, the linear velocity of a particle is along the circumference of a circle. It is different at different points on the circle.

Why is the angular velocity vector perpendicular to motion?

So why do we point the angular velocity vector perpendicular to the plane? Because it’s convenient. Vectors can’t be curved because they’re nothing more than a magnitude and a direction. So we use the direction perpendicular to the plane to convey the rotational direction.

Is velocity and acceleration perpendicular in circular motion?

In a circular motion the acceleration is always perpendicular to the velocity.

How does linear velocity relate to angular velocity?

The greater the rotation angle in a given amount of time, the greater the angular velocity. Angular velocity ω is analogous to linear velocity v. We can write the relationship between linear velocity and angular velocity in two different ways: v=rω or ω=v/r.

How is linear motion different from rotational motion explain with one example?

Linear motion involves an object moving from one point to another in a straight line. Rotational motion involves an object rotating about an axis. – Examples include a merry-go-round, the rotating earth, a spinning skater, a top, and a turning wheel.
