Pre-Activity: Force on Objects Pics

__** (Part 1- Answer the following) **__

1 Write Newton’s first Law. p. 389 2 Tell what inertia is. p. 390 3. Explain figure 14 p. 390 Tell what happened and how it shows inertia.

__** (Part 2- Write and draw the following. Answer #4.) **__ Newton’s first law/Law of Inertia

1. An unbalanced force is required to change an object’s motion. (Draw stick figures or describe the picture) 2. An object’s motion will continue unless changed by a force. Use stick figures or describe the picture. 3. An object at rest will stay at rest unless a force moves it. More massive objects have more inertia. (1st Law)

4. Which object has more inertia? Which object’s motion will change more? Which object experiences an unbalanced force? Draw and include the subjects in all answers.
