Using the force table, components of a vector can be found experimentally by suspending masses from two orthogonal strings which oppose the mass and string representing the vector in question. if 155 g is suspended at 210 degrees , what masses must be suspended at 0 degrees and 90 degrees to balance this force? (a) 182 g at zero, 105 g at 90 (b) 105 g at zero, 105 g at 90 (c) 121 g at zero, 70 g at 90

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

c. newton's third law of motion

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.
