1. What is the speed of the marble?
Answer: Students measure the distance a marble rolls and the time it takes to roll. They then calculate the speed using the equation: Speed = Distance / Time.
2. What is the speed of the ball?
Answer: The speed of the falling ball as a function of time is v = 9.8 (m/s2) t and the distance traveled is d = ½ 9.8 (m/s2) t2.
3. Which object rolled faster?
Answer: You should find that a solid object will always roll down the ramp faster than a hollow object of the same shape (sphere or cylinder)—regardless of their exact mass or diameter. This might come as a surprising or counterintuitive result!
4. What is the time difference between the marble and the ball?
Answer: Have you ever dropped something and wondered how fast it was moving while falling? (If it was something fragile, you might not have been thinking about this at the time—you were likely too busy trying to grab the object!) We all know that gravity forces an object to fall.
5. What can you conclude from this activity?
Answer: We conclude that when mass or force is increased the Displacement is increased.
Hope your kind enough to make me brainliest :(
