Name: Date: Part 1: Will It Accelerate? Cut & Sort Directions: Cut out the free-body diagrams. First, separate into two piles: ‘accelerating’ and ‘not accelerating.’ Then divide the accelerating objects into ‘speeding up’ or ‘slowing down.’ Lastly, divide the non-accelerating objects into ‘non-zero velocity’ and ‘zero velocity.’ After you finish gluing, use this side to help you answer the questions on the back.

What do all eight of the accelerating free-body diagrams have in common? 2. What do all eight of the non-accelerating free-body diagrams have in common? 3. Draw your own free-body diagram below that matches each of the criteria: Accelerating Not Moving Moving at Constant Speed 4. Can you tell from a free-body diagram alone if an object is moving at a constant velocity or at rest? Why? 5. Draw your own free-body diagram below that matches each of the criteria: Speeding Up & Moving Left Slowing Down & Moving Left Speeding Up & Moving Right Slowing Down & Moving Right 6. Does positive acceleration always mean speeding up? Explain with an example. 7. Provide an example to explain that negative acceleration does not always mean slowing down. 8. An object experiencing zero net force could be …. (circle all that apply): a) Speeding up b) Slowing down c) Not moving d) Moving at a constant velocity 9. An object experiencing non-zero net force could be … (circle all that apply): a) Speeding up b) Slowing down c) Not moving d) Moving at a constant velocity © 2021 Amanda Chapman. All rights reserved.
