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.

If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.
How acceleration and mass are related if the force is constant?
For a given mass, the acceleration is directly proportional to the net force acting on the mass, and is in the same direction as the net force. In other words, the larger the net force acting on an object, the greater its acceleration. When the net force is zero, the object is either at rest or moving with a constant velocity.
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
If the mass of an object does not change a constant net force on the object produces a constant what?
F=ma, if F is constant and m is constant, then a is constant... its acceleration.
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.
What changes as an object moves with a constant acceleration?
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
If, as you say, its acceleration is "constant", then the average is exactly equal to that constant.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
If an object is moving in a circle with a constant speed Its acceleration is constant in what?
It is constant in magnitude. It is changing in direction.
Can an object with constant speed be accelerating?
Yes. 'Acceleration' means either speed or direction is changing. If direction is changing,then there is acceleration, even if speed is constant.
Can the direction of the velocity of an object change keeping the acceleration constant?
In order to change the direction of the velocity, acceleration is absolutely required. And as long as you've got it, there's no reason why it can't be constant. An object moving in a circle at a constant speed ... like a TV satellite ... has constant acceleration, and the direction of its velocity is constantly changing.
Can an object be moving if acceleration is zero?
Yes. Acceleration is defined as a change of speed and/or direction of motion. If the speed and direction of motion are constant, then there is no acceleration.
Can the direction of velocity of an object change keeping the acceleration constant?
Yes. dv/dt = a=constant.
If there is a constant velocity of 30 ms. What is its acceleration?
Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.
What is an object that moves with constant position?
An object that moves with constant position will have constant velocity or acceleration. This is said to be moving in positive direction and maintains the position.
