acceleration
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
The object's acceleration is zero ... it continues moving in a straight line at a constant speed.
-- An object with no net force on it continues moving at constant speed in a straight line.If it's not moving in a straight line, then there must be net force acting on it.-- "Acceleration" is the word for the situation where either speed or direction of motion changes.Even if speed is constant, acceleration is present if the direction is changing.
The only thing that causes or influences acceleration of an object is force.
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
acceleration
Acceleration = Final velocity - Initial velocity / time
If it's moving in a curve or some other non-straight path, then yes. If it's moving in a straight line, then no.
A straight slanted slope on a velocity-time graph indicates that the object is moving with a constant acceleration.

If a body is moving at constant velocity in a straight line, the acceleration is zero and the net force acting on it is zero. F = ma F = m x 0 F = 0
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
