An object has balanced forces acting on it. Which of the following describes the result these balanced forces have on the object
dexar [7]

Answer:

C.It remains at rest or moves at constant speed in the same direction.

Explanation:

First, remember the Newton's 1st law of motion which states that the object at rest will remain at rest and that in motion will stay in motion with the same speed and same direction unless acted by unbalance forces.

Balanced forces on an object occur when two forces at act on an object are equal in size and act in opposite direction. In this case, a stationary object will stay at  rest while an object moving will continue to move at the same speed and same direction.

An object acted by balanced forces is said to be at equilibrium, thus the state of motion will be maintained.The object will not accelerate. A good example of an object acted by balanced forces is an object at rest or in constant motion such as a car that stopped at red-light signal or a car travelling at a constant speed.
