According to Newton's law of motion rate of change of momentum is directly proportional to applied force.
A man falling from certain height receives more injuries when he falls on a marble floor than when he falls on a heap of sand.Explain.Why?.

According to Newton's law of motion,the force depends on the rate of change of momentum. What happens to the linear momentum when the force is absent?

According to Newton's law of motion,the force depends on the rate of change of momentum. Why is it more difficult to rotate a stone by tying it to a longer string then a shorter string?

According to Newton's law of motion,the force depends on the rate of change of momentum. A man jumping out of a moving bus with his head forward.What should he do in order to land safely?

The rotational analogue of force is moment of force, also called torque.The possibility of falling backward with the ladder is more when you are high upon the ladder than when you just begin a climb. Explain why.

Sand is pouring from a pipe at the rate of 12 cm^3 / s. The falling sand forms a cone on the ground in such a way that the height of the cone is always one-sixth of the radius of the base. How fast if the height of the sand cone increasing when the height is 4 cm ?'

The viscous force exists when there is a relative motion between the layers of the fluid. The speed time graph of a falling sky diver is shown below. During the fail he opens his parachute. Which part of the graph shows the sky diver falling with terminal velocity?
