Why is velocity constant in straight line?

Constant velocity vs acceleration To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path thus, a constant velocity means motion in a straight line at a constant speed.

When a particle moves in a straight line it may have constant velocity?

Constant velocity means that the object in motion is moving in a straight line at a constant speed. This line can be represented algebraically as: x=x0+vt x = x 0 + vt , where x0 represents the position of the object at t=0 , and the slope of the line indicates the object’s speed.

Why does object moving in a straight line have angular momentum?

For it to have a non-zero angular momentum, its line of path is displaced from the axis about which the angular momentum is calculated. An object moving in a straight line that does not go through the axis of rotation has an angular position that changes with time. So, this object has an angular momentum.

When particle moves in a straight line it may have?

A : For a particle moving in a straight line, its acceleration must be either parallel or antiparallel to velocity. R : A body moving along a curved path may have constant acceleration.

What happens when velocity is constant?

In order for the velocity to be constant, the magnitude of the velocity (or speed) and the direction of the velocity must not change. Therefore, an object that travels with constant velocity covers the same distance during each time interval and moves in the same direction during the same time interval.

When a particle is moving with constant acceleration then its speed is?

The rate of change of the velocity of a particle with respect to time is called its acceleration. If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration.

Can a particle moving in straight line have angular velocity?

A straight line is an arc of infinite radius. So, its time rate of change has a limit that tends to 0. So, its angular velocity is almost zero.

Can a particle moving in a straight line have angular momentum?

How to find the angular momentum of an object moving in a straight line. People forget that an object moving in a straight line (having linear momentum) can have angular momentum. For example, let’s say we throw a ball at one end of a stick (see Figure 1). The stick can pivot around point O.

What will happen to a particle moving freely at a constant velocity?

A particle moving in a circle, does not move with a constant velocity. Its velocity changes continuously, as the direction of velocity vector is changing continuously. Albeit it is the speed of the particle which does not change with time.

When a particle is moving with constant acceleration then choose the correct statement?

Among the following, the correct statement is (multi or single option) a)If the acceleration of an object is constant,then it must move in a straight line.
