Predicting Future Motion - 3rd Grade Science

1. Which option best describes constant speed: equal distances in equal times or changing distances in equal times?

   Equal distances in equal times. Constant speed means no acceleration or deceleration.

2. Which option best describes a straight line on a distance-time graph for equal time steps?

   Constant speed (equal distance in equal time). Straight lines show unchanging speed.

3. What is a pattern in motion data?

   A repeated or predictable change in position over time. Regular sequences help predict future positions.

4. Identify the next position: 1 m, 1 m, 2 m, 2 m, 3 m, 3 m, ___ m.

   4 m. Pattern alternates: single, single, double, double.

5. Which option best describes a distance-time graph that curves upward (gets steeper over time)?

   Speeding up (distance increases faster each time). Curved upward means increasing speed.

6. What is the best definition of direction in motion when predicting where an object will go?

   The way an object moves, such as left, right, up, or down. Direction tells which way motion occurs.

7. What is the best meaning of predict in science when you use a pattern in motion?

   To state what will happen next based on a pattern. Scientists use patterns to forecast future events.

8. What does direction tell you when describing motion?

   The way an object moves, such as left, right, up, or down. Direction shows which way motion occurs.

   $8$ cm. The pattern increases by $2$ cm each time.

10. Which option is the best prediction: A pendulum goes Left, Center, Right, Center, Left, $\_\_$.

    Center. Pendulums pass through center between extremes.

11. Which graph best shows slowing down on a position–time graph: line gets steeper or line gets flatter?

    Line gets flatter over time. Flatter slope means slower motion.

12. What is a repeating back-and-forth motion pattern called?

    Oscillation (back-and-forth motion). Like a pendulum swinging repeatedly.

13. Identify the pattern type: an object travels less distance each second than the second before.

    Slowing down (decreasing speed). Deceleration means covering less ground each interval.

14. What is the best definition of a reference point used to describe motion?

    A fixed place used to compare an object's position. Reference points help measure changes in position.

15. What is the best prediction when an object moves the same distance each second?

    $1$ m. Distance decreases by $1$ m each second.

25. What is a simple rule to find total distance for constant speed?

    Total distance $=$ (distance each time) $\times$ (number of times). Multiply speed by time for constant motion.

26. What is the best prediction when a pattern shows the object stops (positions stay the same)?

    It will remain at the same position until a force changes it. Objects at rest stay at rest without forces.

    $5$ m. Distance increases by $1$ m each second.

30. Which graph best shows speeding up on a position–time graph: line gets steeper or line gets flatter?

    Line gets steeper over time. Steeper slope means faster motion.

31. What does it mean if an object is not changing position over time?

    $4$. Subtract $2$ from $6$ to continue the pattern.

36. What is the best definition of position when tracking motion patterns?

    An object's location compared to a reference point. Position describes where something is relative to a starting point.

    It returns to the same positions over equal time intervals. Repeating motion returns to same spots regularly.

54. What is a cycle in motion?

    One complete repeat of a motion pattern. Like a swing going back and forth once.

55. Which tool is most useful for measuring time when tracking a motion pattern?

    A stopwatch or clock. Time measurement is key for tracking patterns.

    The next value will change by the same amount again. Consistent patterns continue their established trend.

68. What does it mean if equal time intervals show equal changes in position?

    The object is moving at a constant speed. Same distance covered in same time means steady speed.
