Q: The product of mass and acceleration is called.
  • A. Pressure
  • B. Impulse
  • C. Thrust
  • D. Force
Correct Answer: Option D - The rate of change of momentum is directly proportional to the applied force. The larger the force acting on a body, greater is the change in its momentum. Since change in momentum is equal to the product of mass and the rate of change in velocity and the mass of the body remains constant, so the rate of change of momentum is directly proportional to the rate of change of velocity i.e., acceleration. Hence force (F) is directly proportional to mass (m) and acceleration (a) F = ma
