The forces on the object must be unbalanced. When adding up ALL the Forces on
an Object, If the result is not Zero, then the Object will Accelerate in the direction
of the sum of the forces.
If the sum of all forces on an object is zero, then the object remains in constant, uniform motion. 'Constant uniform motion' means motion in a straight line at a constant speed. The physical description of such motion is "constant velocity". "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction.
Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
An object will remain at rest if the net force acting on it is zero. An object will continue to move at a constant velocity if the net force acting on it is zero and there is no external force to change its velocity.
doing some homework? A net force vector/imbalance can either increase velocity (positive acceleration), decrease velocity (negative acceleration) or effect zero acceleration (perpendicular).
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.
A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.

Because of its velocity (velocity is the rate of change of position), an object will move. An object is stationary if it has no velocity because it will not be able to move without velocity. Therefore, you can tell that an object has moved because of velocity.
An object will remain at rest if the net force acting on it is zero. An object will continue to move at a constant velocity if the net force acting on it is zero and there is no external force to change its velocity.

The condition for an object to stay at rest or if moving, keep moving at a constantvelocity is that the sum of forces acting on the object be zero or that no force actson the object.For an object to increase its velocity, in other words to accelerate, there has to bea force acting on the object. The force is the one responsible for the accelerationof the object. Recall Newton's 2nd law of motion:F = m∙awhere 'F' is the force acting on the object with mass 'm', and 'a' is the acceleration the object experiences.Read more: What_are_the_conditions_for_an_object_to_stay_at_rest_to_keep_moving_at_constant_velocity_or_to_move_with_increasing_to_velocity
You have three separate situations here:1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.
If the sum of all forces on an object is zero, then the object remains in constant velocity. Constant velocity means motion in a straight line at a constant speed. "Rest" is just constant velocity with a speed of zero. If the sum of all forces on an object is NOT zero, then the object's velocity must change. The change may consist of speeding up, slowing down, or turning in a different direction. If the sum of the forces is in the same direction as the object's motion, then the object must speed up.
