EQ&BR ESSENTIAL QUESTIONS & bell ringers
EQ: How can you describe the motion of a projectile thrown from Earth’s surface? From space? “We haven’t failed. We now know a thousand things that won’t work, so we are much closer to finding what will.”—Thomas Edison

Instructions for Vocabul ary Sentences--FORCES obj . 6.03 – 6.06
Instructions: Write a meaningful sentence for each key term or phrase, then describe how you
remember the term. Your description can be a drawing or in words. Examples for the terms “gravity” and “motion” are shown. Underline the vocabulary terms in your sentences.
Term My sentence with term used in context My Way to Remember (e.g. drawing or mnemonic)
gravity Without gravity, I would not be stuck on Earth’s surface. Gravity keeps our ancestors in their graves.
motion To describe motion, you must have a point of reference. motion, move, movement, momentum
Key Terms 1. acceleration 2. balanced forces 3. inertia 4. force
5. friction 6. net force 7. unbalanced forces 8. gravity
9. Newton’s 2nd Law of Motion 10. Newton’s 3rd Law of Motion
