A body on application of constant force moves with uniform

Options :
  1. Speed
  2. Velocity
  3. Acceleration
  4. Momentum

Answer and Explanation :-

Answer: Option 1


Speed is the distance travelled per unit time. In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity. Newton's First Law of Motion states that 'Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.' Based on that principle, a body on application of force will move with uniform speed, since speed is a scalar quantity. A scalar quantity or parameter has no directional component, only magnitude.
