practical physics and experimental chemistry week 2 quiz

Question or Hint Answer or Word

Newton's first law of motion Objects at rest will remain at rest, and objects in motion will continue to move with a constant velocity, unless acted upon by an external force.
inertia The tendency of an object to resist changes in its state of motion.
constant velocity The velocity of an object remains the same, with no acceleration.
external force A force that is applied to an object from outside, causing a change in its motion.
net force The sum of all forces acting on an object. If the net force is zero, the object will remain at rest or move with a constant velocity.
physics science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe.
motion change with time of the position or orientation of a body.
