Yes. An object moving at constant velocity has zero acceleration. The constant velocity van be any constant including zero velocity.
Mathematics acceleration a=dv/dt = 0. Solving this gives v = constant.
no
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
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.
Such and object is said to be in equilibrium. No acceleration and no force.
Yes. Velocity is speed per unit of time with a direction vector telling you which way the object in question is moving. Acceleration is a change in velocity - in any part of velocity. If something like, say, a rock is in deep space (a zillion light years from anything) and it's moving along unaffected by any gravity or other forces, it has some velocity (some speed in a given direction, or is moving at some distance per unit of time in a given direction), but it isn't changing speed or direction. If something is moving without changing its speed or its direction (either of which requires a force to act on the object - to accelerate the object), it has zero acceleration. Such an object is said to have a constant velocity and will have zero acceleration. Certainly if an object is not moving, it has zero velocity and zero acceleration, but that's probably not what is being asked. It has velocity (zero) and no acceleration. To recap, an object can have a non-zero velocity and zero acceleration.
it cannot be same as the acc. is not zero
Yes, for example, a car moving at constant speed.
As long as acceleration is zero, the object's velocity is constant.
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
It is not possible for acceleration to have zero acceleration because the force acting on the object is gravity and g=9.8m/s squared. Gravity is the acceleration It can however have a zero velocity
zero
Whenever velocity is constant, the acceleration is zero. This also works when the velocity is zero, the acceleration is zero. That pretty much means the object isn't moving. But, yes/ If velocity is constant, accleration is zero.
Yes. For example, if you throw an object up into the air, this will happen when it reaches the highest point. At that moment, its velocity is zero; on the other hand, at any moment, the object is accelerating downward at 9.8 meters per square second.
Yes. For example a swinging pendulum has zero velocity at the turning point but acceleration is not zero.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
When an object is in equilibrium, the acceleration is zero. When the acceleration is zero, the velocity does not change; the non changing velocity includes the case when the velocity has value zero.
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
