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.

∙ 12y agoI'm pretty sure a cheetah can do that.
Newton's first law of motion states that an object at rest will remain at rest and an object in motion at a constant speed will remain in motion in the same direction at the same speed unless acted upon by another external force. This force creates an additional acceleration on the object. I'm thinking of a ball in free fall being stopped by the ground and "bouncing" it is under constant acceleration and until it makes contact with the ground to apply a external force thus an external or additional acceleration.
I would say no it can't unless it's mass changes during the reversal of direction. But then that wouldn't be constant acceleration either
=========================================
Everybody is overthinking this.
A ball tossed straight up has constant downward acceleration, due to gravity.
As soon as the downward acceleration eats up the initial upward velocity,
the ball peaks, the velocity becomes downward, and the ball starts to drop.
Acceleration is constant from the instant the ball leaves the hand.

immediately take off in the opposite direction. Think a stone that you toss
straight up. It has constant acceleration (the acceleration of gravity) as it
slows down, comes to rest at the top of its arc, and immediately starts down.

a=(v-v0)/t

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 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 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 the velocity reverse the direction when acceleration is constant?
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.
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.
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 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.

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.

Can an object with constant acceleration reverse its direcrion?
Yes. For instance, if you throw an object up, then (ignoring air friction) it will have a constant downward acceleration of about 9.8 meters/second squared. After a while, this acceleration will make it go downwards again.
What happen to object with velocity and acceleration in opposite directions?
It slow down, and eventually reverse direction.
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.
When flow can reverse its direction regularly it is called?
Alternating Current (AC) reverses its flow constantly, unlike DC (constant current) which flows in one direction only.
