Homework Help Overview

The discussion revolves around the concepts of gravity, specifically focusing on the behavior of two identical balls dropped from rest under constant acceleration. Participants are exploring the relationships between position and velocity in a gravitational field.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are attempting to understand the implications of dropping two balls at different times and questioning whether the distance between them changes over time. There is also a request for the general equations of motion under constant acceleration.

Discussion Status

The discussion is ongoing, with some participants expressing uncertainty about the velocities of the balls and the relevant formulas for free fall. Guidance has been offered in the form of basic formulas, but there is no consensus on the answers to the posed questions.

Contextual Notes

Participants are grappling with the definitions and implications of distance and velocity in the context of free fall, and there appears to be a lack of familiarity with the relevant equations of motion.

1. Two identical balls are dropped from rest, one at t=0, and the other a second later. Does the distance between them increase, decrease or remain the same.? Explain.

2. Write the general equations, in one dimension, for position and velocity of an object which experiences a constant acceleration.

Someone please help..i have no idea how to answer this. Thanks

Do you know how to do #2?

For #1, just think about it. In between t=0 and t=1, will the balls be getting farther apart? After t=1, will the balls have identical velocity?
 
no they will not have identical velocities. so yea they will be the same distance between them. I don't know 2,

Are you sure? What is the formula for distance of free fall in a gravity field? At the 3 second mark how far are they apart. At the 5 second mark how far apart are they?
 
i don't know wat formula ur tokin abt
