Can final velocity and acceleration be the same?
When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down.
Can acceleration be equal to velocity?
So the velocity can be changed either by changing the speed or by changing the direction of motion (or both). Therefore, it may be possible that the speed is constant, but the velocity is changing because the direction is changing. In this case, acceleration will be non-zero and equal to the rate of change of velocity.
Is acceleration equal to velocity over time?
Acceleration equals the change in velocity divided by the change in time.
How does acceleration relate to velocity?
Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.
What is the relation between acceleration and velocity?
Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity. Velocity is a vector quantity because it consists of both magnitude and direction. Acceleration is also a vector quantity as it is just the rate of change of velocity.
When acceleration is zero What happens to velocity?
If the acceleration is zero, then the velocity will neither increase or decrease: the velocity will be constant.
Is acceleration proportional to velocity?
No. For example, the drag force due to any fluid, on an object moving with respect to it, is proportional to its velocity and in the direction opposite to it (approximate relationship). Hence the acceleration is also proportional to the velocity and in the direction opposite to it.
