Have you ever wanted to be an inventor? now is your chance! for this portion of the assessment you will design your own rube goldberg device. rube goldberg devices use simple everyday items and take advantage of simple potential to kinetic energy conversions. when several of these conversions are combined, the device is able to perform a simple task, just like the one in the lab activity.

the answer is b

explanation:

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.
