- 17. Multiple ChoiceWhat does the term inertia mean?
"Newton's first law focuses on the law of inertia."The tendency of an object to resist a CHANGE in its state of motion.Opposes the motion of one object moving past another.The speed and direction of a moving object.Forces that do not cancel each other out when acting together on a single object. - 18. Multiple ChoiceWhat does the term friction mean?
" The oil in my car reduces the friction on my engine."Using force to move an object.How fast an object's position is changing with time at any moment.Opposes the motion of one object moving past another.A wheel with a groove in the rim. - 19. Multiple ChoiceWhat does the term acceleration mean?
"The car showed acceleration by going faster and faster."A change in velocity.When my car goes faster.A push or pull on an object. - 20. Multiple ChoiceAn ice skater at rest pushes against a sled at rest, causing both the skater and sled to move away from each other with different accelerations. This is an example best described byNewton’s first law of motion for objects at rest.Newton’s first law of motion for objects in motion.Newton’s second law of motion.Newton’s third law of motion.
