What will be the velocity of a particle when it reverses its direction of motion?

Yes, the velocity of the object can reverse direction when its acceleration is constant. At At t = 0 sec, the magnitude of velocity is 2m/s and is moving in the forward direction i.e.v (t) = -2. The negative sign here direction of motion, we consider the forward direction to be negative and backward to be positive.

When a particle moves along a straight line the motion is called as?

translatory motion
Explanation: When the motion of a body is confined to only one plane, the motion is said to be plane motion. When the motion of a body is along a straight line path, it is called translatory motion.

How will you describe the motion of a particle moving in a straight line at 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.

What happens to the acceleration of the body if the body is traveling in a straight line with a linearly increasing velocity?

Its dimensions are [L1M0T-2]. Acceleration can be positive, negative or zero. If the velocity is increasing then acceleration is positive. If the velocity is increasing then the direction of acceleration is same as that of the velocity of the body.

How do you know when a particle reverses direction?

If a and v are opposite signs, P is decelerating. Speed increases when velocity and acceleration are positive. Speed decreases when velocity increases/decreases and acceleration does the opposite of velocity. The particle P reverses (changes) direction when v=0 and a≠0.

When a particle in rectilinear motion reverses its direction?

Further, rectilinear motion involves only one way of changing direction i.e. the particle under motion can only reverse motion. The particle can move either in positive x-direction or in negative x-direction. There is no other possible direction valid in rectilinear motion.

When the particle moves along a straight line the motion is called as Mcq?

Explanation: Rectilinear Motion is the simplest type of motion and is along a straight line path. Such a motion is also known as translatory motion. 8.

When a particle moves along a curved path then the particle has?

A particle moving along a curved path undergoes curvilinear motion. Since the motion is often three-dimensional, vectors are used to describe the motion. A particle moves along a curve defined by the path function, s. The position of the particle at any instant is designated by the vector r = r(t).

How is the position of a particle moving along a straight line described by a number How is the direction of motion specified by the number describing position?

Answer: Mark the initial position as 0. and then if distance moved is x m then mark the distance as x. if your distance is x then it is in the direction of positive axis and if -x then it is moving in the direction of negative axis.

When a body moves in a straight line in the same direction its?

When a body moves along an imaginary straight line towards a single direction, its motion is said to be in one direction. This means that the body moves in a single direction for all the time. When the body moves in one direction, its motion is called as rectilinear motion.

When the body is moving in a straight line or path then the body is said to be in?

When a body moves in a straight line then the motion of the body is said to be “ RECTILINEAR MOTION ” . It is also called 1-D motion.

Where does the particle change direction?

Speed increases when velocity and acceleration are positive. Speed decreases when velocity increases/decreases and acceleration does the opposite of velocity. The particle P reverses (changes) direction when v=0 and a≠0.
