what do radius vectors of particles really mean and how can they be at a different angle with velocity v.
A radius vector is a line segment that connects the center of a circle to any point on its circumference. It is a commonly used term in geometry and physics to describe the position of an object in relation to a fixed point or origin.
The angle of a radius vector is typically measured in degrees, with 360 degrees representing a full circle. The starting point of the angle is usually the positive x-axis, with the angle increasing in a counterclockwise direction.
The velocity of an object can be described as the rate of change of its position. In the context of radius vectors, velocity is represented by the change in the angle of the radius vector over time. The direction of the velocity is determined by the direction in which the angle is changing.
In circular motion, the radius vector of an object is constantly changing as it moves around the circle. This results in a changing velocity, as the angle of the radius vector is constantly increasing or decreasing. The velocity is highest when the angle is changing the fastest, which occurs at the points furthest from the origin.
Yes, the position of an object can be determined using the relationship between radius vectors, velocity, and time. By knowing the initial position and velocity of an object, and the rate at which the radius vector is changing, the position of the object can be calculated at any given time using mathematical equations such as the kinematic equations.
