Can you have acceleration with 0 velocity




















Explanation: For the most part velocity is not zero if an object is accelerating. Related questions What is the difference between distance and displacement? Is displacement directly proportional to velocity?

How does average velocity differ from instantaneous velocity? How can I calculate the change of velocity? How do speed and velocity differ from each other? How do velocity and acceleration differ? How do displacement and distance differ? At zero velocity, there is still a net force acting on the object due to the spring, so the object will accelerate in the opposite direction. In this whole process, the acceleration is constant, but the velocity is still zero at its highest point. A mathematical equation like this can also be deducted for your spring problem, and then you'll see that the velocity will in fact be zero when the acceleration is maximum, and that the velocity will be maximum for zero net acceleration.

Yes, it possible, in this case — ve acceleration known as retardation. Answer: An object can have an Eastward velocity while experiencing a Westward acceleration. The car will slowly stop as there will be a decelerration or in other words, an acceleration Westward.

Accelerating objects have a changing velocity — either due to a speed change speeding up or slowing down or a direction change. A car moving eastward would be described as having an eastward velocity.

And a car moving westward would be described as having a westward velocity. Originally Answered: can an object have eastward velocity experiencing a westward acceleration? An object headed east, undergoing a positive westward acceleration, is slowing down. A positive acceleration in one direction is the same as a negative acceleration in the opposite direction.

A westward acceleration while moving northward? Yes, an object can be moving at the same time that it is also slowing down. During this period, its acceleration is in the opposite direction of its velocity.

Since it is possible for an acceleration to be both positive and decreasing, it is possible that an object can be both increasing in speed and decreasing in acceleration.

As mentioned earlier in Lesson 1, an object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction. It is accelerating because the direction of the velocity vector is changing. Yes reversing the direction of acceleration will produce retardation. Consequently the velocity will start decreasing with time but the direction of motion will be maintained till the velocity is reduced to zero and get reversed.

Acceleration increases as velocity increases, and it decreases as velocity decreases. As radius increases, acceleration decreases, and as it decreases, acceleration increases. A body in uniform circular motion has uniform speed but at every point its direction of velocity changes, so its motion is accelerated.

Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity. If the acceleration is zero, then the slope is zero i. If the acceleration is positive, then the slope is positive i. If the acceleration is negative, then the slope is negative i. Acceleration is also a vector quantity, so it includes both magnitude and direction.

The velocity-time graph shows a line with a positive upward slope positive acceleration ; the line is located in the positive region of the graph corresponding to a positive velocity.

The acceleration-time graph shows a horizontal line in the positive region of the graph positive acceleration. Begin typing your search term above and press enter to search. Press ESC to cancel.
