How are scientific theories different than laws or hypotheses? Theories can be changed to better fit new evidence.
Theories can remain the same over hundreds of years.
Theories can be proven beyond any doubt or questioning.
Theories can develop without any supporting observations.

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.

i believe the answer is electric potential.

explanation:

the ima (higher than 1m) will be greater than the ima with the height of 1m.
