Mass given by the equation a = F/M

M = F/a is called inertial mass. Clearly, higher the a mass means lesser the acceleration. Thus mass of a body resists the acceleration, i.e., rate of change in velocity coming up due to external force or in other words it is the measure of inertia of a body.

# How does Newton's second law of motion give the concept of inertial mass?
