Q1 What happens when:
a) A bus starts suddenly
b) A passenger jumps out from a moving car
c) A car enters a curved path
2. State Newton’s third law of motion and its applications.
3.Give examples from daily life where Newton’s third law is applicable
4.Concept of conservation of momentum through derivation
Answers
a) When suddenly a bus starts the passenger in the bus feels a movement.
b) When a passenger jumps out of a moving car so there is the ( law of inertia) so he slightly fell down because of this law. You may know!!
c) The car moves in a circular path due to the centripital force causing friction between the tires and the road. and that's why the car will move in a larger- radius curve and leave the roadway.
d) The third law of Newton Stats that "Every action has an equal and opposite reaction" . For example- if you are sitting in a boat and forces the water behind to let the boat go forward so the water also puts equal and opposite force to your boat and that's why your boat moves.
e) like in your daily days you suddenly kicks the wall and you feels pain why?? because the wall also pushes the same force and that's why you feels pain in your hands.
f) Conservation of Momentum
That f- m*a
force - mass * acceleration.
