### What happen to an object when it has positive acceleration?

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

### What is happening to an object when it has an acceleration?

### Does acceleration have a negative or positive value if the velocity is increasing speed?

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

### How can an object slowing down have an acceleration that's not negative?

If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.

### What undergoing acceleration does an object change its speed from 10 ms to 3 ms?

Positive acceleration!(:

### Is it possible for a falling object to have a positive acceleration?

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

### Can an object's rate of acceleration decrease and its speed increase at the same time?

Yes, assuming the object's rate of acceleration remains positive during the time it is decreasing.

### An object with constant velocity has positive acceleration?

Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.

### When An object speeds up it has what acceleration?

For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).

### What is positive accelerations?

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.

### What is the value of acceleration of an object in freefall?

If the object is falling close to earth the acceleration would be 9.81m/s^2. Be sure to define direction as positive or negative in the problem! (When I do problems I like to define the down direction as positive so I don't have to deal with too many negatives)
