What if velocity is negative?

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).

Does velocity can be zero?

Yes, an object can have zero velocity and still be accelerating simultaneously. Let us consider an object moving in the forward direction. Then the object will start to move in the backward direction.

Is velocity can be positive negative and zero?

Answer: velocity can be positive ,negative and zero..

What does a zero velocity mean?

Explanation: An object having zero velocity implies that it is stationary at a particular location. If we plot it on a velocity-time graph which represents velocity on the y -axis and time on the x -axis, it is represented by x -axis. Value of y (velocity), is 0 for all values of x (time).

Can velocity be negative Yes or no?

Velocity can be a negative as it’s a vector quantity. A positive velocity denotes that the object is traveling in the positive direction as defined by the coordinate system. A negative velocity denotes that the object is moving in the opposite direction.

Can velocity be negative Class 9?

The ratio of distance travelled and the time taken by a body can be zero but not negative. Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.

Can velocity be zero if displacement is zero?

Velocity is the rate of change of displacement. If displacement is zero, the rate of change of displacement is zero so the velocity is zero.

What is the difference between positive and negative velocity?

Velocity is a vector quantity. It has a (positive) magnitude and a direction. For one-dimensional motion, this can be represented as a one-dimensional vector, which looks just like a positive or negative number. A negative number indicates motion in the direction of the negative axis.

Is it possible to have a negative velocity?

So, from a merely mathematical perspective, yes, you can have a negative velocity. This merely means that you are moving in the opposite direction of your preferred direction. From the driver’s perspective going into reverse would be viewed as moving backwards, or in our terms moving with a negative velocity.

What does it mean when the velocity is negative?

A negative velocity means that the object which has the negative velocity is moving in the opposite direction of an object moving at a positive velocity. This is a question of frame of reference. The possibility for the velocity is what makes it different to the speed. Speed is only positive.

Can instantaneous velocity ever be negative?

By finding two points on the curve that are very close and calculating the average velocity, you can estimate the instantaneous velocity at one of those points. Instantaneous velocity, like average velocity, can be calculated to be negative or positive.
