## What is velocity when displacement is negative?

The direction of the average velocity is the same as the direction of the displacement, while the direction of the instantaneous velocity is the same as the instantaneous direction of motion. While the object is moving in the negative direction, its instantaneous velocity is negative.

## Can a graph have negative displacement?

Displacement is a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot.

## Is displacement negative if velocity is negative?

The displacement is decreasing (a negative velocity) → yet another shape.

## Can a body have constant speed and variable velocity?

Yes, a body has constant speed as well as variable velocity. Consider an example: A particle moving in a circular path with a uniform circular motion.

## What is the difference between a negative position and a negative displacement?

In one dimension the direction is indicated by the sign: negative if to the left and positive if to the right. If one follows the rule of always subtracting the first position from the second, the sign always works out to be positive if the displacement is to the right and negative if the displacement is to the left.

## Can displacement time graph have negative slope?

Velocity is a vector quantity which tells us that displacement per unit time. Rate of change of velocity is known as acceleration. Therefore, the slope of the velocity-time graph represents the acceleration of the object. Hence, if the slope is negative, this means the velocity of the object is decreasing with time.

## Does negative velocity mean deceleration?

Again, acceleration is in the same direction as the change in velocity, which is negative here. This acceleration can be called a deceleration because it has a direction opposite to the velocity.

## What does negative velocity indicate?

An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).

## How do I find displacement on a position time graph?

On your displacement-time graph, it is more correct to title the vertical axis “position”. From the vertical axis, you can then calculate the “displacement” by simply subtracting one position from another between any two times.

## What do displacement vs time graphs represent?

Displacement of an object is defined as how far the object is from its initial point. In displacement time graph, displacement is dependent variable and is represented on the y-axis while time is the independent variable and is represented on the x-axis and is also known as position time graph.

## What are velocity vs. time graphs?

Velocity vs. time graph shows the variation of velocity with time. If the velocity-time graph is a straight line parallel to the x axis, the object moves with constant velocity. If the graph is a straight line (not parallel to the x axis), the velocity is increasing uniformly i.e.

## What can be determined from a velocity time graph?

A velocity-time graph shows the speed and direction an object travels over a specific period of time. Velocity-time graphs are also called speed-time graphs. The vertical axis of a velocity-time graph is the velocity of the object. The horizontal axis is the time from the start.
