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 else can I help you with?
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.
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.
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.)
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 is happening 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 kind of acceleration occurs when an object speeds up: positive, negative, neutral, or zero?
When an object speeds up, it experiences positive acceleration.
What does a positive acceleration position-time graph indicate about the motion of an object?
A positive acceleration position-time graph indicates that the object is speeding up or moving in the positive direction.
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 or deceleration is negative acceleration. It is opposite to the direction of velocity.
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.
