Your heart does work to pump blood through your body. Each minute, 5.0 LL of blood travels through your circulatory system. The pressure drops from 16 kPakPa as it exits the heart to approximately zero as it returns to the heart. We can calculate the work required to move a fluid volume VV through a pressure difference with a formula very similar to the one you saw for work in gases.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
