Acceleration is taken as negative when an object is decelerating or slowing down. In this case, the acceleration vector points in the direction opposite to the velocity.
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
Not necessarily so. Negative (deceleration) could be growing or decreasing in magnitude. The cause is going to be the Force that is acting on the system. If the Force is increasing, the acceleration will be also.
Retardation or deceleration is negative acceleration. It is opposite to the direction of velocity.
A negative acceleration refers to a decrease in velocity, while a positive acceleration refers to an increase in velocity. Negative acceleration occurs when the speed of an object is decreasing, such as when it is slowing down. Positive acceleration occurs when the speed of an object is increasing, such as when it is speeding up.
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
It cannot have negative velocity, it can have negative acceleration.
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
Positive acceleration = speeding up. Negative acceleration = slowing down.
Oh, dude, so like, when something is slowing down, it's actually experiencing negative acceleration. It's like the opposite of when you speed up, you know? So, they call it retardation because it's like saying, "Hey, slow down, negative acceleration coming through!" It's just a fancy way of saying things are getting slower, man.
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
A plane landing is a negative acceleration - "negative" meaning it slows down.
Positive is speeding up and negative is slowing down
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction

Acceleration is any change in velocity. Negative acceleration is when the change is such that the speed decreases.
