Which of the following is a property of an object not a result of something happening to the object? select one: weight a. b. inertia c. momentum d. force

option (b)

Explanation:

Th weight of the body is equal to the product of mass of the body and acceleration due to gravity. So, it depends on the acceleration due to gravity.

Inertia is the inherent property of the body which always resists any change in the body. It does not depend on any factor. mass is the measure of inertia.

Momentum is the product of mass of body and the velocity of the body.

Force is the product of mass and the acceleration of the body.

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.
