## Are polar coordinates curvilinear?

Example: Polar coordinates (r, θ) are the curvilinear coordinates, and the Jacobian determinant of the transformation (r,θ) → (r cos θ, r sin θ) is r.

### What is the formula of curvilinear motion?

= r/ t . The instantaneous velocity is the time-derivative of position v = dr/dt . The velocity vector, v, is always tangent to the path of motion. The magnitude of v is called the speed.

**What are different ways of motion in curvilinear motion?**

Curvilinear motion describes the motion of a moving particle that conforms to a known or fixed curve. The study of such motion involves the use of two co-ordinate systems, the first being planar motion and the latter being cylindrical motion.

**What do you mean by curvilinear?**

Definition of curvilinear 1 : consisting of or bounded by curved lines : represented by a curved line. 2 : marked by flowing tracery curvilinear Gothic. Other Words from curvilinear More Example Sentences Learn More About curvilinear.

## What do you mean by curvilinear coordinates?

Definition of curvilinear coordinates : a system of geometrical coordinates in which if only one of the coordinates is allowed to vary the locus may be a plane or twisted curve.

### What do u mean by curvilinear coordinate?

The Cartesian coordinates of a point (x,y,z) are determined by following straight paths starting from the origin: first along the x-axis, then parallel to the y-axis, then parallel to the z-axis, as in Figure 1.7. 1. In curvilinear coordinate systems, these paths can be curved.

**When in a curvilinear motion what is the direction of particle velocity?**

It changes the length of the velocity vector. It may act in the opposite direction of v, slowing the particle along the path (as it does at position 3), or in the direction of v, increasing the particle’s speed along the path (in positions 1 and 2).

**Which of the following is an example of curvilinear motion?**

Throwing of a javelin at some angle with the horizontal will occur in the development of an acceleration at some angle with the velocity so the path followed will be a curved path and hence, we call this motion a curvilinear motion. Therefore, throwing of a javelin is an example of curvilinear motion.

## What is the difference between curvilinear and circular motion?

Answer: circular motion:circular motion is a special case of curvilinear motion where the object moves around a fixed point in a circular ( closed ) path.
