1. Explain what inertia is.
What causes inertia in an object that is at rest? In an object that is moving? Draw a picture which shows an example of inertia.
2. Why has no work been done if there is no displacement? Use the equation WFx D to explain your answer.
3. What is one example of a resistant force? Explain why it is called resistant.
