Top Answer

Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position.

If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.

0An example of positive acceleration?

positive acceleration helps to increase the velocity for positive direction while negative acceleration resists the motion.

Positive acceleration = speeding up. Negative acceleration = slowing down.

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.

The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.

No. "Positive acceleration" means increasing speed. The acceleration is usually constantin typical Physics examples and applications.

Positive acceleration is an increased speed, i.e. acceleration acts in the same direction that the object is moving.

Positive acceleration is an increase in velocity in the direction in which motion is being measured.

Positive acceleration could be called "speeding up" if you felt like it.

Actually, it depends on how you define the coordinate axes, but usually when moving forward, negative acceleration decreasesspeed, positive acceleration increasesit.

no a body can only have positive velocity .sometimes it have negative acceleration

The acceleration is positive.

Positive acceleration ==> speeding up Negative acceleration ==> slowing down

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

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

If you define the positive direction as pointing down, then the falling object has positive acceleration.Its magnitude is 9.8 m/s2.

when the acceleration of the body is positive its mean that its velocity is increasing and the speed of the motion also increases and speed will decrease when acceleration is negative.

Yes, it just depends on how you define which way is "positive". If you define the "backwards" direction to be the positive direction, acceleration will be positive when going "backwards". Note that if we define the axes like this, going "forwards" will give the car a negative acceleration.

positive acceleration

An object with constant velocity has no 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.

positive acceleration is when things speed up; negative acceleration is when things slow down; and zero acceleration is when things do not speed up or slow down, this is called constant speed, or no change in velocity.

If you define the "up" direction as "positive", then the acceleration is negative, because it is downward. If you define "down" as positive, then acceleration is negative. You can use any convention; just be sure to be consistent within a particular calculation, to avoid errors.

Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
