Question

Forces, applied on an object, along the same direction add to one another; if the forces are applied in opposite direction (on a given object), the net force acting on it is the difference between the forces, this net force acts along the direction of the larger force. If a box of mass 'm' has to be moved from position A to position B, the force has to be applied in such a manner so that the box moves in the direction towards position B. The magnitude of force applied depends on its mass 'm' which determines the force with which box is pressing the surface on which it is lying 4


(a) Define balanced forces?

(b) Which force opposes the motion of the box on the surface on which it is kept ?

(c) Does the above mentioned force remain constant or does it keep on changing (within limits) ?

(d) Name the kind of forces (balanced or unbalanced) which can bring about change in the position, speed or direction of motion of the object on which they are acting.​

Answer 1

Answer:

Forces Acting in Opposite Directions

In other words, one force is subtracted from the other to calculate the net force. If the opposing forces are equal, or balanced, the net force is zero, as it is for the book. ... In this case, the object will move in the same direction as the net force.

When two forces act in the same direction, they add together. ... Unbalanced forces acting on an object will change the object's motion. Unbalanced forces can also stop a moving object. The three main forces that stop moving objects are friction, gravity and wind resistance
