12.3. Acceleration http://www.ck12.org
Apply Concepts
- The velocity of a car on a straight road changes from 0 m/s to 6 m/s in 3 seconds. What is its acceleration?
Think Critically
- Because of the pull of gravity, a falling object accelerates at 9.8 m/s^2. Create a velocity-time graph to represent
this motion.
Points to Consider
Acceleration occurs when a force is applied to a moving object.
- What is force? What are some examples of forces?
- What forces might change the velocity of a moving object? (Hint: Read the caption toFigure12.12.)
