For an object that is speeding up in the positive direction what does the displacement vs. time graph look like?
The displacement vs. time graph for an object that is speeding up in the positive direction will have a positive slope that is increasing over time. This indicates that the object is covering more distance in a shorter time interval as it accelerates.
Is displacement negative in physics?
In physics, displacement can be positive, negative, or zero, depending on the direction of the movement. Positive displacement means the object has moved in a certain direction, negative displacement means the object has moved in the opposite direction, and zero displacement means the object has not moved at all.
If displacement is decreasing then velocity is?
If displacement is decreasing, then velocity can be positive, negative, or zero, depending on the direction of motion. If the object is moving in the positive direction, a decreasing displacement may result in a positive velocity. If the object is moving in the negative direction, a decreasing displacement may lead to a negative velocity. If the object is stationary and its displacement is decreasing, the velocity is zero.
How does the direction of the acceleration along determine if the object is speeding up or slowing down?
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then 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.

Positive displacement means the object has moved in a certain direction, negative displacement means the object has moved in the opposite direction, and zero displacement means the object has not moved at all.
Can a position time graph tell in which directionthe displacement of an object is?
Yes. If the slope is positive, the direction of the displacement is positive (e.g. north, east, or right). If the slope is negative, the direction of the displacement is negative (e.g. south, west, or left).
If displacement is decreasing then velocity is?
If displacement is decreasing, then velocity can be positive, negative, or zero, depending on the direction of motion. If the object is moving in the positive direction, a decreasing displacement may result in a positive velocity. If the object is moving in the negative direction, a decreasing displacement may lead to a negative velocity. If the object is stationary and its displacement is decreasing, the velocity is zero.
How does the direction of the acceleration along determine if the object is speeding up or slowing down?
Take the component of the acceleration along the direction the object is moving. If this component is positive (the acceleration vector, or the relevant component, points in the same direction as the movement), then 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 is the definition of negative velocity?
Observe that the object below moves in the negativedirection with a changing velocity. An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
For an object that is speeding up at a constant rate in the positive direction what does the velocity vs time graph look like?
A line angled upward
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.
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.
How can you tell if acceleration is positive or negative?
Acceleration is positive when an object is speeding up in the positive direction (e.g., increasing velocity), and negative when the object is slowing down in the positive direction or moving in the negative direction (e.g., decreasing velocity). The sign of acceleration depends on the direction of the change in velocity relative to the direction of motion.
When is positive work done in a physical system?
Positive work is done in a physical system when the force applied to an object is in the same direction as the displacement of the object.
