2. Centripetal acceleration means…? “center-seeking”

3. All circular motion has acceleration directed towards…? The center of motion

4. The acceleration of an object in circular motion does not depend on…? Answer

5. The acceleration of an object in circular motion does not depend on…? mass

6. All objects in circular motion move faster on the edge of the circle or in the middle? Answer

7. All objects in circular motion move faster on the edge of the circle or in the middle? The edge

8. The equation for centripetal force is just which equation re-written? Answer

9. The equation for centripetal force is just which equation re-written? Newton’s Second Law

10. All objects in freefall have the same speed. T or F. It depends on if there is air resistance or not.

11. In 10 words or less, list the three laws of motion. 1st: objects in motion, stay in motion, etc.

12. The equation for weight is a rearranged form of Newton’s First Law. Answer

13. The equation for weight is a rearranged form of Newton’s First Law. No, 2nd Law.

14. Daily Double

15. Explain Newton’s 2nd Law in words. A net force on a mass causes and acceleration.

16. The recoil of gun is explained by Newton’s 1st Law. T or F. F, Newton’s 3rd Law.

17. The vertical speed of a projectile never changes. False, it is always accelerating.

18. What is the equation for the horizontal component of a projectile? Answer

19. What is the equation for the horizontal component of a projectile? Vx = v0 cosθ

20. What is the definition of a projectile? Any object that is kicked, shot, or thrown and acted upon by gravity.

21. What is the relationship between vertical velocity and horizontal velocity of a projectile? Answer

22. What is the relationship between vertical velocity and horizontal velocity of a projectile? They are independent of each other

23. Which is bigger: a mile or a kilometer? A kilometer

24. What charge does a proton have? Positive

25. Why is the sky blue? Answer

26. Why is the sky blue? Because of the diffraction of sunlight through the atmosphere.
