The mass of a given object can be determined using the known values of force acting on it which causes a known value of acceleration by the formula of mass = force / acceleration.
Explanation:
The Newton’s second law of motion gave the derivative formula for the calculation of force. Force is which acts on specified mass of object causes it to accelerate.
Therefore,
force on the body = body's mass multiplied by its acceleration caused.
Thereby, when to know,
the body's mass = Force acting on the body is divided by the acceleration caused.
