What is force...?
Answers
Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
Force is a push or pull that can change shape , size , acceleration , direction of an object .
____________
Two or more forces acting on an object are said to be Balanced if the net effect produced by all of them on object is zero .
two or more forces acting on an object are said to be Unbalanced definite effect produced by two or more forces on an object is not zero .
Inertia is that property of a body by virtue of which it opposes any change in its state of rest , state of motion or direction .
Force is a vector quantity and its SI unit is Newton ( N ). Its CGS unit is Dyne .
