30 POINTS PLS ANSWE For each of Newton’s three laws of motion, compare hitting a 500-g croquet ball with a mallet to hitting a 56-g tennis ball with the same mallet and the same amount of force.

The croquet ball velocity v will be 56/500 the tennis ball velocity V after the impulse.

The second law (force = mass*acceleration) says that the same force will accelerate the balls by the inverse of their mass. That is, the force will continuously change the momentum:

f = 500a = 56A

Therefore a = f/500 and A = f/56

and a/A = 56/500.

The croquet ball will accelerate less, for whatever time or distance you apply the force.

The third law: for every action, there is an equal and opposite reaction. So, if in fact you apply the same force to strike each ball, you will feel the same reaction. That’s probably easier to do for a quick strike (the impulse case above) than for a long, smooth acceleration over distance, because the balls have very different elastic response. The body can tell how equally you applied force!

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.
