If you through an object up, at its highest point it will have zero velocity (only for that instant). But all the time it is subject to an acceleration of 9.8 meters per square second (downward).
Accelaration
an object in free fall and an object's velocity is decreasing by the same amount every minute
if velocity is constant, that means then the net acceleration acting on the object is equal to zero
Acceleration is any change in the speed or direction of an object's motion.
A net force will cause an acceleration. That is to say, if a net force acts on an object, the object's velocity will change.
When an object is not accelerating at all. It has constant velocity.
Accelaration
accelaration?
since accelaration is the change in velocity of an object per unit time......if velocity is zero then there is no acceleration.its nt possible
freefall
an object in free fall and an object's velocity is decreasing by the same amount every minute
freefall
if velocity is constant, that means then the net acceleration acting on the object is equal to zero
According to Newton's 2nd Law,Net Force = Mass x AccelerationTherefore, if an object is undergoing acceleration, it follows that you definitely are looking at an object with a net force.With a net force, the sum of the forces acting on the object is not equal to zero, and so forces acting on it are not balanced.As for the last question, the query has not been stated clearly. Rephrase, please? (:

force=mass*accelaration force/mass=accelaration 4/2=2m/s2
