• B. The mass of the object

• C. The size of the object

4. How can you measure acceleration in an Algodoo project demonstrating Newton's Second Law?

• A. By the color intensity

• B. Using the Graph Tool

• By counting the number of objects

5. Which of the following best describes how Algodoo can illustrate Newton's Second Law?

• A. By showing how objects can move on a screen

8. If you increase the mass of an object in Algodoo, what happens to the acceleration if the same force is applied?

• A. It increases

• B. It stays the same

• C. It decreases

9. What does adjusting the 'friction' parameter in Algodoo do when simulating Newton's Second Law?

• A. Changes the object’s color

• B. Affects how easily the object moves across surfaces
