What does a negative slope on a velocity vs time graph represent?
Rate of change of velocity is known as acceleration. If acceleration is negative it is also known as retardation or deceleration. Therefore, the slope of the velocity-time graph represents the acceleration of the object. Hence, if the slope is negative, this means the velocity of the object is decreasing with time.
What does it mean when velocity has a negative slope?
time graph reveals pertinent information about an object’s velocity. For example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity.
What does it mean when a velocity graph is negative?
The velocity-time graph shows a line with a negative (downward) slope (meaning that there is a negative acceleration); the line is located in the negative region of the graph (corresponding to a negative velocity).
When the slope of an object is negative it indicates the object is moving?
An object moving in the negative direction with positive acceleration is slowing down (since the a vector is in the opposite direction as the motion). So on a p-t graph, this object will be represented by a line which slopes downwards (- velocity) and levels off or becomes more horizontal over time (slowing down). 32.
What does slope of velocity time graph represent?
-As the slope of a velocity-time graph represents the acceleration of the body, the area under the curve represents the displacement or the distance travelled by the body with the applied velocity and time.
What does a negative slope look like on a position vs time graph?
If a position-time graph has a negative slope, it means that the object is moving with a negative velocity or, in other words, moving in the opposite direction.
What does it mean when a position vs time graph is negative?
The object is moving from slow to fast since the slope changes from small big. The object has a negative or leftward velocity (note the – slope). The object has a changing velocity (note the changing slope); it has an acceleration.
What does negative velocity and negative acceleration mean?
Negative velocity = You move backwards. Negative acceleration = You slow down or you go faster in the backwards direction.
Can velocity be negative?
An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).
Can the position-time graph have a negative slope?
Yes. The slope of position time graph gives velocity. And velocity can be negative.
What does the slope represents?
Slope means that a unit change in x, the independent variable will result in a change in y by the amount of b. slope = change in y/change in x = rise/run. Slope shows both steepness and direction. With positive slope the line moves upward when going from left to right.
What does slope of position-time graph indicate?
The slope of position time graph represents speed or velocity of the object or particle.
