What is your hypothetical research question? (Must include population of study, independent variable-with at least two levels, one dependent variable-some type of measure or score, experimental and control groups).Turn your research question into a null and alternate hypothesis. What is the best way to collect data and minimize sample bias? How are you going to collect information to choose the best representative sample?What ethical considerations should be made with the study you proposed to ensure that your experiment would conform to the scientific community’s expectations of ethical research?

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.
