Want this question answered?
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
That rate of change, along with the direction in which it's changing, comprise the object's acceleration.
Since a = F / m, to change a, there must be a change either in the net force applied on the object or in the mass of the object.
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
With changing the "state of motion", I assume you want to change the velocity. What you need here is a force, applied on the object. The amount of acceleration is given by Newton's Second Law.

In Simple motion, there is no force being applied. The moving object moves in a straight line with constant velocity. In acceleration, there is a force applied. The object's velocity is changing. The first derivative of acceleration is velocity. The first derivative of velocity is distance. (Derivative is a calculus thing.)

When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
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.
Object shows acceleration when the force applied on it is increased.
force=mass*acceleration Therefore acceleration = force/mass This means you can change an objects acceleration in two ways, either by applying a force to the object (for example pushing a shopping trolly). You can also change the acceleration of an object by changing the mass of the object (putting shopping in the shopping trolly)
If the object is in free-space, and any force applied over a period of time will change the velocity of an object. Force = mass * acceleration. Acceleration = velocity / time. Therefore, Force = mass * velocity/time.
