Does negative acceleration have constant acceleration?
Not necessarily so. Negative (deceleration) could be growing or decreasing in magnitude. The cause is going to be the Force that is acting on the system. If the Force is increasing, the acceleration will be also.
This depends on what the graph represents. If it is a graph of velocity on the vertical and time on the horizontal, then if acceleration is at a constant rate, the graph will be a straight line with positive slope (pointing 'up'). If acceleration stops, then the graph will be a horizontal line (zero acceleration or deceleration). If it is deceleration (negative acceleration), then the graph will have negative slope (pointing down).
When a car's velocity is negative and its acceleration is negative what is happening to the car's motion?
the car is at a constant speed --------------------------------------------------------- I'm pretty sure that if the acceleration is negative, the car is slowing down. But if the velocity is negative, the car is either heading south or down (velocity refers to speed and direction.. according to my physics teacher).
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when…
Good Question. If you think in terms of keeping the object's acceleration constant the whole way through, then more mass will slow down the acceleration. Unfortunately, this is never the case. An object's acceleration cannot be "slowed down"; it can either have a negative acceleration or a positive acceleration. Hope my answer helped! (:
There will by no change in the mass, which is constant, but the unbalanced force will cause the object to accelerate. Acceleration can be in a positive direction or a negative direction ("deceleration"), or it can be circular, in which the acceleration changes constantly, even if the velocity remains constant.
If a car is traveling at a constant speed of 60 miles per hour for 30 minutes what is the acceleration?
On a graph of speed versus time, where time is plotted along the horizontal (X) axis and speed along the vertical (Y) axis: -- constant speed (zero acceleration) produces a straight, horizontal line; -- constant acceleration produces a straight, sloped line; the slope of the line is equal to the acceleration; -- if the acceleration is positive, the line slopes up to the right (speed increases as time increases); -- if the acceleration is negative…
