Astudent wanted to investigate whether or not the temperature of the water would affect the solubility of sugar. she had three glasses of water, each with 200ml of water in them. one was at 10 c, the second at 25 c and the third was at 40 c. she found that the warmer waters dissolved more sugar. what are the independent and dependent variables?

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.
