Smart Charts
Review for test
Construct a Smart Chart
• Smart charts are OK on the final test.
• Should have the major topics we have
covered in the triad
• Drawings are good.
• You should have 3 ideas in each topic
• Use note format – if you know it, don’t
write it.

Vocabulary
Forces
Gravity - force of attraction caused
by Mass
Balanced forces
Unbalanced Forces
Motion
Acceleration
Speed
Velocity
Friction
Orbit
Laws of Motion
Charles’s Law
Boyles’ Law
Newton’s first law - Law of inertia object at rest, stays at rest, object
in motion wants to stay moving in
a straight line at constant speed.
An unbalanced force can change
both of these. Newton’s 2nd & 3rd
laws
