Class8_Science_Force and Pressure_Force
Force is a kind of push or a pull on an object. The interaction of one object with another results in a force between the two objects. If a force acts on an object in the direction of its motion, then the object moves faster. If a force acts on an object opposite to the direction of its motion, then the objects slows down. Force may also change the direction of motion of an object. The effect of force changes with the direction of its application. Forces acting on an object in the same direction add to each other, while forces acting opposite to each other results in the difference of the forces.
