  • Inertia is a property due to which a body in a state of rest or a state of motion continues to be in that state untill and unless an external force acts upon it.
  • This force with the help of Newton's first law of motion can be mathematically expressed as the product of ass (m) of the body and the acceleration (a) possesed by it.
  • begin mathsize 12px style Force space left parenthesis straight F right parenthesis equals space Mass space left parenthesis straight M right parenthesis cross times Acceleration space left parenthesis straight a right parenthesis end style
  • This explains that, the force of inertia will be greater for a body of a larger mass or a body with a higher acceleration.
  • Therefore, amongst a truck and a car, inertia will be more in a truck due to its mass which is greater than that of a car.
