Want this question answered?
describe three situations in which a force changes the velocity of an object. let at least one of the situatinos involve the force due to gravity
it can be both. If its unbalanced the object will move with the force that is greater. Balanced forces have a net force of zero.
work done on an object zero by a force would be zero isif the displacement of the object is zero
No. If the sum of all the forces on the object is not zero, then the object's acceleration is not zero, meaning that either its speed or direction of motion, or both, are changing.
Force causes acceleration, not motion. A moving object undergoing zero net force will continue to move in the same direction at the same speed.
If an object is not moving, then the net forces working on it are zero. If there were a non-zero net force, the refrigerator would move in the direction the force was applied.
If the net force is not zero then the object will move in the direction of the greater force.
If an object doesn't move, then the net force on it is called "zero".

The object does not move. Newton's Law of Motion states that an object with stay at rest unless acted upon by a force.
Yes, but an object with net force of zero may still be moving. The net force is zero if the object is not accelerating.
It depends on your setting. If the net force on an object is zero than the object will move with a constant speed. It will also move with a constant speed (but not velocity!) if a force forces the object to move in a circular motion.

No. If the sum of all the forces on the object is not zero, then the object's acceleration is not zero, meaning that either its speed or direction of motion, or both, are changing.
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.
Accelerate. Using Newton's second law, Net Force = mass * acceleration rearranged the equation acceleration = Net Force/mass so when the force is non zero and the mass is non zero, the object will accelerate. Note: This does not mean that the object is always at rest when the force is zero, it simply means the velocity is constant (when velocity =0, the object is at rest).
