It has to change its speed or direction. In order for that to happen, there has to be a net force applied to the object which is non zero.
In order for an object to accelerate, it's only necessary
that all of the forces on it don't add up to zero.
its acceleration will be increased
its acceleration will be increased
The acceleration of the object increases.
its acceleration will be increased
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
(change in speed) divided by (time required to make the change)This number is the magnitude of average acceleration.
Object's weight = (object's mass) multiplied by (acceleration of gravity in the place where the object is)
Acceleration
An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
An object's acceleration is the result of a force being applied to it. When that happens, the magnitude of the resulting acceleration is equal to the force divided by the object's mass, and the direction of the acceleration is in the direction of the force.
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration
