Top Answer

Yes. When the change in velocity (final velocity-initial velocity) is negative, the acceleration will be negative. For example, when a vehicle slows down to a stop, the change in velocity is negative because the final velocity is less than the initial velocity, which makes the change in velocity negative. Therefore the acceleration will be negative. a=(vf-vi)/(t2-t1)

0Deceleration or negative acceleration is when an object or thing gets slower

I goes the negative direction ;)

Yes, all a negative acceleration means is the object is slowing down.

Both velocity and acceleration can be negative when an object is slowing down, or when an object accelerates backwards, which is a negative direction, such as a car backing out of a driveway.

Retardation or negative acceleration or deceleration.

Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.

Yes. An object slowing down but still moving in a positive direction has a positive velocity but a negative acceleration.

No. A negative acceleration could mean a change in direction

An object acted on by a net force of zero has no acceleration.

Observe that the object below moves in the negativedirection with a changing velocity. 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).

Anything that is not moving or is moving at a constant speed has zero acceleration. An object that is slowing down has a negative acceleration, an object that is speeding up has a positive acceleration.

Positive acceleration results in the object speeding up, such as a car going from 0mph to 30mph. Negative acceleration is the object decelerating, such as using the brake in a car.

The acceleration is opposite the direction the object is moving, so the acceleration is negative and southward.

Negative acceleration, also known as deceleration.

Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.

In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)

Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration. Colloquially, people speak of deceleration, however the correct term is negative acceleration.

Acceleration is a vector. It has both a magnitude and a direction. So you first have to choose which direction is positive. Lets say we choose "left" as negative and "right" as positive. If an object is increasing speed (positive magnitude) while moving Right (positive direction) its acceleration is Positive' If an object is decreasing speed (negative magnitude) while moving Right (positive direction) its acceleration is Negative. If an object is increasing speed (positive) while moving Left (negative direction) its acceleration is Negative. If an object is decreasing speed (negative) while moving Left (negative) its acceleration is Positive. For vertical motion you would probably choose "up" as positive and "down" as negative.

It will be in the negative direction.

whe the object slows down

Negative Acceleration:Negative Acceleration refers to an object whose speed decreases as it moves away from its original starting position.Actually, that's not entirely correct. Acceleration is a vector quantity and, therefore, depends on direction. If an object 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.Think of it this way: if the acceleration vector is pointed in the same direction as the way an object is moving, the object speeds up. If the acceleration vector is pointed opposite the direction of motion, it slows down.

When an object slows down, its acceleration is negative (in a linear sense), or in a direction opposed to its motion (in a vector sense).

its slowing down gatorrificperson says.......The acceleration is in the opposite direction of the velocity

Acceleration is the change in velocity of an object. If an object is travelling at an unchanging speed, its speed is neither increasing (which would make a positive acceleration) nor decreasing (which would make a negative acceleration). Thus, the acceleration is 0.

Negative acceleration, slowing down a moving object.
