Questions
  1. Statement is true
    No
    Statement
    A force is needed to keep a body in uniform motion.
  2. Statement is true
    Yes
    Statement
    In practice a force is needed to counter friction.
  3. Statement is true
    Yes
    Statement
    Aristotle's view on this was wrong.
  4. Statement is true
    Yes
    Statement
    With no external force, a moving body keeps moving.
  5. Statement is true
    Yes
    Statement
    Galileo's work on inclined planes led to the law of inertia.
The chapter opens by correcting this directly: a force is needed in practice only to counter friction, not to keep a body moving. Source: syllabus Physics, Ch 4 Laws of Motion.

Missing parts
  1. Answer
    uniform
    Choices
    1. uniform
    2. circular
    3. accelerated
  2. Answer
    external
    Choices
    1. external
    2. internal
    3. frictional
  3. Answer
    acceleration
    Choices
    1. acceleration
    2. velocity
    3. momentum
Complete the statement
Every body continues in its state of rest or of {0} motion in a straight line, unless compelled by some {1} force to act otherwise. Put simply, if the external force is zero then the {2} is zero.
The law as the chapter states it. Source: syllabus Physics, Ch 4 Laws of Motion.
