Answer from: cynayapartlow88

Option c) mass

Explanation:

With the increase in energy in energy of an object there will be an increase in its mass.

Also from Einstein's mass-energy equivalence,

$E = mc^{2}$

where

m = mass of the object

c = speed of the object (usually speed of light or close to it)

which states that energy and mass are inter convertible.

From which it can be concluded that if an object acquires additional energy, it also acquires additional mass.

Answer from: Quest

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 -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [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.
