The correct answer is velocity.

Key Points

  • Acceleration is the rate at which velocity changes with respect to time.
  • The ultimate outcome of all forces applied to a body, according to Newton's second law, is its acceleration. Acceleration, a vector quantity, determines the frequency at which a body's velocity varies. The formula can be used to express acceleration.
  • The overall movement of an object, regardless of direction, is referred to as distance.
  • The term "displacement" refers to a shift in an object's position. It's a vector quantity with a magnitude and a direction.
  • The product of a particle's mass and velocity is called momentum. Momentum is a vector quantity in the sense that it has both a magnitude and a direction.
