Chapter- 11 Force and Pressure: 2 23/11/21, , Exploring Forces:, teachoo.com, , Push Pull, , , , 1. When force is applied on an object in the same direction, it makes the object moves. When we push, the heavy box in the same direction, it makes the box slide., , 2. What will happen if the two forces act in the opposite direction? If two persons pushes the box from, both sides, if the strength of both person is same, then the box will not move. And if one of the persons, is stronger than the other, then the box will slide towards the weaker side., , 3. The strength of a force is usually expressed by its magnitude., 4. A force can change the state of motion:, , Force applied on an object may change its speed. If the force applied is in the direction of the object's, motion, its speed increases. The state of motion of an object is described by its speed and the direction, of motion. A force thus, may bring a change in the state of motion of an object., , A(a) Speed, , , , To move a tyre faster it has to be pushed repeatedly
