Can the velocity of an object be negative when its acceleration is positive What about the vice versa?

Assuming rightward is positive, the velocity is positive whenever the car is moving to the right, and the velocity is negative whenever the car is moving to the left. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.

When a car’s velocity is negative and its acceleration is negative what is happening to the car’s motion group of answer choices?

Explanation: The car’s rate of change of position is decreasing. The car is moving but its rate of position increase is coming down. The car will eventually come to a brief stop and begin traveling backward.

Can the velocity of an object be negative when its acceleration is positive give one example?

Yes, the velocity of an object can be negative when its acceleration is positive and vice versa. An example of such a situation is when an object is launched vertically upwards and moves freely under the action of gravity.

What happens when velocity is negative?

Velocity. A positive velocity simply means that the object is moving in the positive direction, as defined by the coordinate system, while a negative velocity means the object is traveling in the other direction.

What happens when velocity and acceleration are negative?

If velocity and acceleration have the same sign, you speed up. If velocity and acceleration have opposite signs, you slow down. Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction.

Does negative velocity mean negative acceleration?

When velocity is negative and acceleration is negative?

An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).

What happens if velocity is negative and acceleration is negative?

If velocity and acceleration have opposite signs, you slow down. Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction.

Does velocity decrease when acceleration is negative?

4 Answers. Sure, as long as acceleration is positive, velocity increases, even if acceleration is decreasing (as long as it doesn’t reach zero). Likewise, as long as acceleration is negative, velocity decreases even if acceleration is increasing.

What if acceleration and velocity are both negative?

If the velocity and acceleration are in the same direction (both have the same sign – both positive or both negative) the object is speeding up. If the velocity and acceleration are in opposite directions (they have opposite signs), the object is slowing down.

Is velocity negative if the slope is negative?

The slope of the line on a position-time graph reveals useful information about the velocity of the object. *If the velocity is positive, then the slope is positive (i.e., moving upwards and to the right). *If the velocity is negative, then the slope is negative (i.e., moving downwords and to the right).

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.

When does velocity become negative?

When velocity is negative, the integral of velocity is also negative. We can think of this negative value as a weighted distance. The number part tells the distance, and the negative sign tells the direction, which is the opposite of the direction travelled when v(t) is 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.

When is the acceleration taken as negative?

Acceleration is a vector quantity, therefore it depends on direction. When a body is moving in a straight line, in the negative direction, its acceleration is positive if its speed decreases with time and negative if its speed increases with time.
