We lurch forward in bus that suddenly slows , this is because of inertia of motion . Inertia of body resist any change in motion . Body wants to stay in state of rest or motion , unless an external force causes change .
So , when bus is moving ,our body with bus is also in state of motion , but when bus suddenly slows down, inertia of our body resist change in its state of forward motion and hence we lurch forward .
Step 2
When the bus picks up speed , we lurch backward due to inertia of rest . When the bus is at rest , our body with bus is also at rest , so when bus speeds up , inertia of our body resist change in its state of rest and hence we lurch backward .
Similarly , when the bus is moving with some constant speed , suddenly picks up the speed , then the inertia of our body resists the change in state motion or increased speed , hence we lurch backward .
Step 3
This law of inertia also known as Newton's first law of motion .
According to Newton's first law of motion, a body continues to be in state of rest or uniform motion along a straight line unless it is acted upon by some external force to change the state .

Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force The magnitude of the tension in the string between blocks B and C is T=3.00N. Each block has mass m=0.400kg.
What is the magnitude F of the force?
What is the tension in the string between block A and block B??We have: A golf ball of mass 0.045 kg is hit off the tee at a speed of 45 m/s. The golf club was in contact with the ball for s. Find (a) the impulse imparted to the golf ball,and (b) the average force exerted on the ball by the golf club
???A box is sliding with a speed of 4.50 m/s on a horizontal surface when, at point P, it encounters a rough section. On the rough section, the coefficient of friction is not constant but starts at .100 at P and increases linerly with distance past P, reaching a value of .600 at 12.5 m past point P. (a) Use the work energy theorem to find how far this box slides before stopping. (b) What is the coefficient of friction at the stopping point? (c) How far would the box have slid iff the friciton coefficient didn't increase, but instead had the constant value of .1?

The spring in the figure (a) is compressed by length delta x . It launches the block across a frictionless surface with speed v0. The two springs in the figure (b) are identical to the spring of the figure (a). They are compressed by the same length delta x and used to launch the same block. What is the block's speed now?A spring gun's spring has a constant force k =400 N/m and negligible mass. The spring is compressed 6.00 cm and a ball with mass 0.0300 kg is placed in the horizontal barrel against the compressed spring.The ball is then launched out of the gun's barrel after the spring is released. The barrel is 6.00 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so the barrel is horizontal. Calculate the speed with which the ballleaves the barrel if you can ignore friction. Calculate the speed of the ball as it leavesthe barrel if a constant resisting force of 6.00 Nacts on the ball as it moves along the barrel. For the situation in part (b), at what position along the barrel does the ball have the greatest speed?
