2.01) a pattern is a(n) (unusual, rare, repeated) arrangement of things.
2.02) (inertia, gravity, friction) is the tendency of an object to resist moving or changing motion.
2.03) a(n) (theory, law, observation) describes something that is always observed to be true.
2.04) newton found, when comparing the two forces of gravity between earth and the moon, that the force of gravity was greater from the (earth, moon).
2.05) (magnetism, electricity, gravity) causes the elliptical orbits of planets around the sun.
2.06) birds fly by flapping their wings in a (random, rhythmic) pattern, which creates lift by (pushing, pulling) against the air.
2.07) the amount of force in a system (increases, decreases) when the system is bigger.

2.08) ____ scale refers to __.
a. the relationship between two or more quantities
b. the amount of something
c. how big or small something is
2.09) ____ proportion refers to __.
a. the relationship between two or more quantities
b. the amount of something
c. how big or small something is
2.10) ____ quantity refers to __.
a. the relationship between two or more quantities
b. the amount of something
c. how big or small something is
2.01) A pattern is defined as a repeated sequence/arrangement.
2.02) Inertia is the property of objects resisting motion changes.
2.03) A scientific law describes consistent, always-observed truths.
2.04) Gravitational force depends on mass; Earth has far more mass than the moon, so its gravitational pull on the moon is stronger.
2.05) Gravity is the centripetal force keeping planets in elliptical orbits around the sun.
2.06) Birds flap wings rhythmically for lift, and they push air downward to create upward lift.
2.07) Larger systems do not inherently have less force; force increases with system size/mass in relevant contexts.
2.08) Scale refers to the relative size (how big/small something is).
2.09) Proportion describes the relationship between multiple quantities.
2.10) Quantity refers to the amount of a substance/thing.
