Doubt about Resultant (net) velocity

In summary, the conversation discusses the motion of an object undergoing horizontal circular motion and the relationship between its angular and linear velocity. The question is raised about adding these velocities, but it is explained that they cannot be added as they are dimensionally different. The object continues to move along the horizontal circle due to the perpendicular direction of its linear velocity towards the center of motion.

So we know that an object undergoing horizontal circular motion, has a angular velocity with direction perpendicular to the plane of motion, and also a linear velocity with a direction perpendicular to the acceleration towards the centre of motion

Question : if we sum/add the linear+angular velocity, wouldn't there be a Resultant velocity, at an angle above the horizontal?something like North-West,
Why does the object still undergoes motion along the horizontal circle(west)??

You cannot add a linear velocity and an angular velocity. They are dimensionally different. It would be like adding an angle to a distance.

1. What is the resultant velocity?

The resultant velocity is the overall velocity of an object, taking into account both its magnitude and direction. It is the vector sum of all the individual velocities acting on the object.

2. How is the resultant velocity calculated?

The resultant velocity can be calculated using vector addition. This involves adding the individual velocities using their respective magnitudes and directions. The direction of the resultant velocity can be determined using trigonometric functions.

3. Can the resultant velocity be negative?

Yes, the resultant velocity can be negative. This indicates that the object is moving in the opposite direction of the positive direction chosen for the calculation. It is important to pay attention to the signs when adding velocities to accurately determine the resultant velocity.

4. How does the angle between velocities affect the resultant velocity?

The angle between velocities affects the magnitude and direction of the resultant velocity. When the velocities are in the same direction, the angle is 0 degrees and the resultant velocity is equal to the sum of the individual velocities. When the velocities are in opposite directions, the angle is 180 degrees and the resultant velocity is equal to the difference between the individual velocities.

5. Can the resultant velocity be greater than the individual velocities?

Yes, the resultant velocity can be greater than the individual velocities. This can occur when the individual velocities are in different directions and the angle between them is less than 90 degrees. In this case, the resultant velocity is the diagonal of a parallelogram formed by the individual velocities, which is longer than either of the two sides.
