Does acceleration have a negative or positive value if the velocity is increasing speed?
Acceleration has a positive value if the velocity is increasing speed. Positive acceleration means the object is speeding up.
When is acceleration of an object positive?
Acceleration of an object is positive when its velocity is increasing over time. This means the object is speeding up in the direction of its motion.
What does a positive acceleration mean?
Positive acceleration means that an object's velocity is increasing over time. This can happen when an object is speeding up in the direction of its motion.
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.
Is retardation positive or negative acceleration?
Retardation is a form of acceleration that is negative, meaning that the object is slowing down. Positive acceleration refers to the object speeding up.
What is happening to an object when it has an 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

Is retardation positive or negative acceleration?
Retardation is a form of acceleration that is negative, meaning that the object is slowing down. Positive acceleration refers to the object speeding up.
How can a positive acceleration produce a deceleration?
If an object is moving in the negative direction (backwards) and experiences a positive acceleration in the positive direction (forwards), it will slow down and decelerate. This is because the acceleration is acting in the opposite direction of the object's velocity, causing it to decrease.
What type of motion would produce positive acceleration in an object?
Positive acceleration in an object can be produced by a force applied in the direction of its motion. This force will cause the object to increase its speed over time.
What MUST be true about an object's acceleration as it is traveling in the positive direction and slowing down?
The object's acceleration must be in the negative direction, opposing its velocity in the positive direction. This negative acceleration is also known as deceleration and causes the object to slow down.
How is a negative acceleration different from a positive acceleration?
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.
How can an object slowing down have an acceleration that's not negative?
An object slowing down can have an acceleration that is not negative if it is moving in the opposite direction of its velocity. In this case, the acceleration would be in the same direction as the object's motion, even though it is slowing down. This can happen, for example, when an object is moving in the positive direction but experiencing a negative acceleration due to a force in the negative direction.
