Can one speed negatively?

Can one speed negatively?

No, speed cannot be negative. Since speed is a scalar quantity and doesn’t have a direction. Velocity on the other hand, can be negative.

Can a particle posses a zero speed and non zero velocity B non zero speed and zero velocity?

(i) No, if the speed of a body is zero it is at rest , so , velocity is also equal to zero, (ii) No, speed of the particle is equal to magnitude of its velocity.

Which statements can be impossible cases in one two dimensional motion?

A body has zero velocity and is still accelerating. The velocity of an object reverses direction when acceleration is constant. An object’s speed goes on increasing even magnitudes of its acceleration decreases.

Which of the following Cannot be true for one dimensional motion?

Graph (b) does not represent one dimensional motion because at the same instant a particle cannot have positive and negative velocity if the motion is one dimensional.

How can you represent one dimensional motion?

Graphical Analysis of One-Dimensional Motion

1. Describe a straight-line graph in terms of its slope and y-intercept.
2. Determine average velocity or instantaneous velocity from a graph of position vs. time.
3. Determine average or instantaneous acceleration from a graph of velocity vs. time.
4. Derive a graph of velocity vs.
5. Derive a graph of acceleration vs.

What we Cannot represent on a speed graph?

Speed of a body in motion should have single value at any instant of time but in graph-B if we draw a line perpendicular to time axis then it will cut the graph at two different points leading us to two different values of speed which is not possible so graph-B is not possible.

Which speed time graph is not possible?

In all the given graph, we heve more than one values of speed corresponding to a single time. The graph must have a unique value of speed corresponding to a single time. Thus all the three graph are not possible.

What is wrong with the speed time graph?

As per graph speed is negative after half cycle which is not possible. For velocity time graph it is correct graph. Aakash EduTech Pvt.

Which graph is not possible for a body in uniform motion?

The distance-time graph for non-uniform motion is not a straight line since speed is variable, it can be a curve or a zigzag line.

Which of the following is not possible for a uniform motion?

2) Swinging pendulum is under the action of gravitational force and is also changing its direction – hence it is not in uniform motion.

Which of the following is not possible for a body in motion?

Answer. Answer: acceleration and mass is not responsible.

Which of the following is possible for a body in uniform motion?

A body is said to be in uniform motion if it travels equal distances in equal intervals of time, no matter how small these time intervals may be. If we draw distance time graph for uniform motion then it will be straight line.
