Ram and Sham boarded a bus for their hometown. They were happy that they got a good seat. When the conductor came to them for ticketing they were surprised to know that they had boarded a wrong bus. They requested the conductor to stop the bus. Sham in a panic did not wait for the bus to stop and tried to jump out of the slowing down moving bus in a direction opposite to the motion of the bus. The conductor pulled Sham back and told him to wait for the bus to stop otherwise he might be seriously injured by jumping out of the bus in a wrong direction.
Q7.(i) Why did the conductor stop Sham from jumping out of the slowing down bus?
Q7.(ii) Why did he tell him that he was jumping in a wrong direction?
Q7.(iii) Which law of motion explains the concept involved in this?
Q7.(iv) State the law.
Q7. (v) What is the other name of this law?

i) Conductor stopped Sham from jumping out of the bus because if he would jump then he would get injured. this phenomenon of getting injured by jumping out of a running vehicle is based on some basic laws of Physics.
ii) he told him that he was jumping in a wrong direction because the door of a bus is at the side direction of the motion of bus so . Thus if he jumps in opposite direction of motion of bus then there will be no force that will be applied on him and thus he will not stop according to newtons first law of motion. Because of not stopping he will get injured.
iii) the concept involved in this can be understood by Newton's first law of motion , since Sham was jumping out of the bus then in the process of Jumping he will gain inertia now when he will reach the ground the inertia off his Feet Will Be destroyed but the inertia of office upper part of body will start to continue and thus there is chances of him to fall forward and this falling can cause injury.
iv) Newton's first law of motion says that a body can't change its position of uniform motion or rest until and unless a net external force acts on it. this happened the same in case of Sham As he jump from bus no external force acted on him and inertia of his upper part of body started to continue.
v) other name of Newton's first law of motion is Law of Inertia and different type of Law of Inertia are inertia of motion ,inertia of ddirection and inertia of rest.
