Yes, it can, if the initial velocity vector of an object was in opposite direction to its

constant acceleration.

Example:

Anything you toss with your hand has constant acceleration after you toss it ...

the acceleration of gravity, directed downward. If you toss it upward, it starts out

with upward velocity, which reverses and eventually becomes downward velocity.

I Don't Believe so, i think once direction of travel is reversed it contradicts the definition of acceleration. technically i suppose this could be true,

If a body was moving due east with an acceleration of 2m/s^2 , and if it could stop literally instantly without deceleration and immediately set off again due west with an acceleration of 2m/s^2 technically it would hav maintained constant acceleration but i think there is a moment there as it changes direction where it can not be constant.

tbh , thinking about it unless the change was absolutely instantaneous which I'm relatively sure is impossible, it would be necessary for there to be some flux in the acceleration.

so in conclusion, NO

The definition of acceleration is: Any change of velocity, that is, speed or direction

of motion.

If an object is undergoing constant acceleration, then that could certainly include

changes in the direction of its motion.

One beautiful example is one object in a circular gravitational orbit around another one.

The gravitational force directed toward the center of the circle, which is what keeps it

in orbit, is a constant acceleration. And in any orbit, the direction of its velocity is

constantly changing.

Yes, it can. A typical example if when you through something up; after a while it will reverse its direction and fall back down again. Acceleration is downward all the time.

Yes. A typical example is that you throw something up, and after a while it falls back down again. Assuming air resistance is negligible, acceleration is constant in this case.

Can the velocity of object reverse direction when its acceleration is constant?

yes, if the acceleration is in the opposite direction of the velocity.


Can a direction of velocity of an object reverse at constant acceleration?

Sure. A pendulum and a park swing both have constant acceleration due to gravity, and the direction of their velocity changes over and over again until they're stopped.


Can a velocity be reversed if acceleration is constant?

Sure. A pendulum, a child's playground swing, and a bullet shot straight up all have constant acceleration, and all reverse direction.


Can an object with a constant acceleration reverse its direction of travel?

Of course. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.


An object that reverses direction while its acceleration remains constant?

An object can reverse direction anytime its velocity is in the opposite direction of its acceleration.A good example is throwing a ball straight up into the air. As soon as the ball leaves your hand, the acceleration due to gravity begins to slow it down. Even though the initial velocity is going straight up, once the ball leaves your hand the acceleration is constantly pulling the ball back towards earth. The ball eventually reaches its peak height, and reverses direction, falling back to earth. This all happens while the acceleration remains constant.


What characterizes constant velocity motion on a position time graph?

A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.


What happen to object with velocity and acceleration in opposite directions?

It slow down, and eventually reverse direction.


When an object's initial velocity is less than its final velocity what does that indicate?

AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.


Can an object reverse its direction while maintaining a constant acceleration?

One answer to this is that all object are in motion all of the time relative to all other objects. With that said, in the context of permanent halt" the only way that an object can be perceived as "halted" is by another object with the same velocity.


When a car is moving in reverse backing from a driveway the driver applies the brake in what direction is the car's acceleration?

The car's acceleration is in forward direction.


Will the acceleration be zero if velocity is constant in velocity time graph?

Yes, by definition, Acceleration is the derivative of velocity. From Calculus, we know, the derivative of any constant function is simply 0. Therefore, any velocity time graph containing a constant velocity function will have an acceleration function = 0. c'=0 or c d/dx=0 also, there is a very simple, and nice progression to things in the field of Kinematics. where given a function, whether it be position, velocity, or acceleration, you can find the other through calculus. the progression for integration goes as follows, jolt (the feeling you get when acceleration changes), acceleration, velocity, position. And the reverse for derivatives. Having a velocity function of something like 55mph, think of it as driving on the freeway, absent of outside forces of friction, air resistance and hills, you never have to accelerate (positively, or negatively) to maintain speed, and the math backs that up. 55 is constant, and the derivative is 0. now if you had a velocity function such as 2x^2 + 5, also known as a parabolic function, you would take the derivative and get an acceleration of 4x, and a jolt of 4, and if you integrate to get position, you would have 2/3x^3+5x. Its all about the math.


How are acceleration velocity and deceleration related?

velocity is the rate of change of displacement with time, or v = dx/dt Acceleration is the rate of change of velocity with time, a = dv/dt deceleration in the true sense doesn't exist, for it is just a term for negative acceleration. You wouldn't say that you are develociting if you are in reverse.
