# Can an object be traveling in the positive direction and have a negative acceleration?

## Can an object be traveling in the positive direction and have a negative acceleration?

Since acceleration is a vector quantity, it has a direction associated with it. The direction of the acceleration vector depends on two things: whether the object is speeding up or slowing down. whether the object is moving in the + or – direction.

### When the acceleration will be positive and negative?

A positive acceleration means an increase in velocity with time. negative acceleration means the speed reduces with time. its a retardation. If the speed is increasing, the car has positive acceleration.

Can a car have a negative velocity and a positive acceleration at the same time?

Yes, for example, a car that is traveling northward and slowing down has a northward velocity and a southward acceleration. A car traveling in the negative x-direction and braking has a negative velocity and a positive acceleration. Give an example where both the velocity and acceleration. are negative.

How can an object have a positive velocity but a negative acceleration?

For example, the velocity could be in the positive direction and the object slowing down or the velocity could be in the negative direction and the object speeding up. Both of these scenarios would result in a negative acceleration.

## Can an object have a positive acceleration and be slowing down?

An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. If acceleration points in the same direction as the velocity, the object will be speeding up.

### Can acceleration be positive when velocity is zero?

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

What is the difference between positive acceleration and negative acceleration?

Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

What is an example where both the velocity and acceleration are negative?

Answer: If the velocity and the acceleration have different signs (opposite directions), then the object is slowing down. For example, a ball thrown upward has a positive velocity and a negative acceleration while it is going up.

## Can an object have a negative acceleration?

An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

### What’s the difference between positive and negative acceleration?

The difference between positive and negative acceleration is the sign or direction of the change in velocity: Positive acceleration means that velocity is increasing (acceleration in the positive direction). Negative acceleration means that velocity is decreasing (acceleration in the negative direction).

Is there an absolute positive or negative velocity?

There is no absolute positive or negative velocity or acceleration. One may also ask, can a velocity be negative? Negative velocity just means velocity in the opposite direction than what would be positive. From the math point of view, you cannot have “negative velocity” in itself, only “negative velocity in a given direction”.

What does acceleration look like on a graph?

Negative acceleration looks like a decreasing (sloping down) function on a graph of velocity. This is because acceleration is the first derivative of velocity, and a negative first derivative indicates a decreasing function. The graph could be a line with a negative slope, such as the one below, but there are other possibilities.
