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.

Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
An object will have constant acceleration if?
An object will have constant acceleration if the net force on it is constant in magnitude.
An object with constant velocity has positive acceleration?
An object with constant velocity has no acceleration.
An object with constant velocity is said to have a constant acceleration true or false?
False. An object at constant velocity is at zero or no acceleration. Of course, if the acceleration is always 0, then it is a constant acceleration of zero.
Can an object with constant acceleration reverse its direction of travel can it reverse its direction twice?
Sure. 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.
Can an object be moving at a constant speed and acceleration?
When the acceleration is at constant 0, then the velocity will be constant.
If an object falls with constant acceleration the velocity of the object must?
Changing at a constant rate equal to acceleration.

Which has zero acceleration an object at rest or moving at constant velocity?
An object at rest has a constant velocity of zero. Both the object at rest and the object moving at constant velocity have zero acceleration.
How are constant speed and constant acceleration different?
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 a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
Can an object with a constant acceleration reverse its direction of travel?
Sure. A common example is when you throw a stone up. The acceleration is basically constant (air resistance tends to be negligible, if the stone is large enough); after a while, it will reverse the direction, and fall back down.
Can acceleration be constant?
An object changing its velocity by 10 m/s in each consecutive second is known asconstant acceleration since the velocity is changing by a constant amount each second. Although an object with a constant acceleration should not be confused with an object with a constant velocity.
Can an object with a constant acceleration reverse it 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.
What is the acceleration of a object that moves at constant velocity?
Acceleration is change of velocity. If velocity is constant ... "no change" ... then acceleration is zero.
If an object has constant velocity what is its acceleration?
Acceleration is the rate of change of velocity. Constant velocity means zero acceleration.
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 an object traveling at constant velocity have acceleration?
No. An object traveling at a constant velocity is not accelerating.
Can an object's velocity reverse direction when its 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.
Does an object moving at constant velocity have zero acceleration?
yes the acceleration is at zero because there is no change in acceleration if the velocity is constant
The constant velocity of a falling object?
A falling object doesn't have constant velocity.It has constant acceleration. That means that its velocity increases at a steady (constant) rate.The rate is called the "acceleration of gravity".
As speed increases for an object in free fall does its acceleration increase also?
No. Acceleration is constant. The effect of constant acceleration is speed that increases at a constant rate.
What is constant for freely falling body?
Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.
What is true about an object in free fall?
The Object has a constant acceleration.
He constant acceleration of an object moving in a circle is called?

State whether there can be an object with a constant acceleration but with zero velocity?
