What is Force?
Pushing and pulling is a part of our daily life. A hawker pushes his cart to move it from place to place (Figure 7.1). A horse pulls a tonga to move the people (Figure 7.2). Similarly, a bicycle moves when you push its pedals. Sometimes, a push or a pull is also applied to stop the moving objects. A wicket keeper when catches the ball, he stops it with his hands (Figure 7.3). There are many other tasks which you do by applying push or pull or both in your daily life. In science, both push and pull are the same things and have one meaning that is force.
