Predicting Motion Patterns

Make observations and measurements of an object's motion to provide evidence that a pattern can be used to predict future motion

Question 1 of 3

A student measures how far a toy car moves during each 2‑second interval after being pushed. The distances recorded are: 4 cm in the first interval, 8 cm in the second, 12 cm in the third, and 16 cm in the fourth. If the same pattern continues, how many centimeters will the car travel in the fifth 2‑second interval?

Question 2 of 3

A toy car moves in a straight line. When the car is pushed, it travels 3 meters in the first second, 3 meters in the second second, 3 meters in the third second, and 3 meters in the fourth second. Using this pattern, how far will the car have traveled after 6 seconds?

Question 3 of 3

Sam makes three cardboard slides that are 5 cm, 8 cm, and 11 cm long. He rolls a marble down each slide and measures how far the marble rolls on the floor after leaving the slide. The marble rolls 10 cm after the 5‑cm slide, 17 cm after the 8‑cm slide, and 24 cm after the 11‑cm slide. If Sam builds a fourth slide that is 14 cm long, how far will the marble roll on the floor after leaving this slide?
