Discussion Overview

The discussion revolves around providing examples of situations where objects can be observed accelerating or decelerating in free fall, as well as those that travel along a trajectory path. The context includes practical demonstrations and experiments related to these concepts.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant suggests using tennis balls thrown at different angles and forces to observe their parabolic trajectories, indicating that the acceleration due to gravity is constant.
  • Another participant mentions the moon as a potential example, though the context of its relevance is not elaborated.
  • A further suggestion involves rolling a tennis ball off a ramp while simultaneously dropping another ball from the same height to compare their motions.

Areas of Agreement / Disagreement

Participants present various examples without reaching a consensus on a single best approach or example. Multiple competing views remain regarding the most effective demonstrations.

Contextual Notes

Some suggestions may depend on specific setups or conditions that are not fully detailed, such as the method of throwing or the environment in which the experiments take place.

PLEASE help can't answer my little sister's question!

She ask me IF I can give a situations where you can observe the objects accelerating/decelerating free fall bodies and objects that traveled at trajectory path

I AM SO ANGRY cause can't answer her question :(((((((

PLEASE HELP ME~~~~~~
-thanks

I am rather frustrated because I can't answer her question.
Please help me.
Thanks
 


I good place to start studying free fall and trajectories is with tennis balls in a field. Have someone throw the ball with different initial forces, and different initial angles and observe the trajectories. The ball follows a parabolic trajectory because the acceleration due to gravity is constant.
 


The moon!
 


Roll a tennis ball off of a ramp into midair. Right when it hits the end, drop another one straight down from equal height. You can do this by hand or set up a neat little contraption to do everything exactly on time.
