Yes. If the sum of the forces is zero, then the object will not accelerate - meaning it will maintain its speed.
Yes, as long as there is no net force acting a body it is in equilibrium. If it is moving with constant velocity there is no acceleration and no net force so it is in equilibrium.
yes
An object that is projectile is an object that is moving through the air. When you throw an object it is projectile.
Motion can only be changed when a force is applied. This may be due to an acceleration field (such as gravity) and the mass of the object, or the force may be applied directly and externally by a second object.

what is an essential characteristic of an object in equilibrium
No, a couple is not in equilibrium, unless there is an equal and opposite force acting against each member of the couple.Be sure to remember that something can still be moving even if it is in equilibrium. It just means it's not accelerating.A2 People often forget that there is a difference between a hypothetical point sized object and a typical sized object when applying the condition for equilibrium. If the forces on an object are equal and opposite it is only the centre of mass that is required to be at rest (or moving at constant velocity). So for a point sized object that means the entire object must be at rest. But for a typical sized object only the centre of mass is required to be at rest. If the applied forces are off centre (as with a couple) it is still possible for the object to rotate about its centre of mass. This is dynamic equilibrium. If one also applies the second condition for equilibrium then you can have static equilibrium (no motion of centre of mass and no rotation) if the system is initially at rest. The second condition for static equilibrium is that there be no net torque on the object. That is the off centre forces tending to rotate the object(say clockwise) must be balanced by other off centre forces which tend to rotate the object counter clockwise.
If the object is moving on constant speed or it's in rest, it is in equilibrium (ΣF=0)
If the object is moving on constant speed or it's in rest, it is in equilibrium (ΣF=0)
A body is refered to be in equilibrium when the forces acting on it cancel each other out, that is, the body has no resultant force. because F=ma , it can also be stated that a body is in equilibrium when there is no acceleration or deceleration in any direction. Therefore, if a body is moving at a steady speed, although it IS moving, it is still at equilibrium. We normally do not think of a moving object as one in equilibrium but that is because in an actual situation, air drag would cause an object to be in equilibrium with 0 velocity.
An object in equilibrium must have the sum of the torques be zero or the object will be rotating and not be in equilibrium.
