Accelerated Motion Problem-easy but I NEED HELP on it

Click For Summary

Homework Help Overview

The discussion revolves around the concept of accelerated motion, specifically in the context of projectile motion and the horizontal component of velocity. Participants are exploring the characteristics of motion under various conditions, including gravitational effects.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the nature of the horizontal component of velocity in projectile motion and its relationship to acceleration. There is an exploration of different scenarios involving gravitational forces and the implications of constant speed versus changing direction.

Discussion Status

The discussion is active, with participants providing insights into the nature of acceleration in various contexts. Some have offered clarifications regarding the assumptions of uniform gravitational fields and the effects of external forces like air resistance.

Contextual Notes

There is an assumption of a uniform gravitational field being discussed, which may influence the interpretation of motion in different scenarios. Participants are also considering the effects of external forces on motion.

[SOLVED] Accelerated Motion Problem--easy but I NEED HELP on it!

Is NOT an example of accelerated motion?

What happens to the horz component of the velocity in projectile motion?
 
Yes, since it stays constant.
 
Well - one could look at each answer and think about the acceleration involved.

Going vertical near a massive body, e.g. Earth or moon, a mass will experience the force (acceleration) due to gravity.

Something that involves a change of direction (something rotating, swinging, oscillating) is accelerating, even if it maintains constant speed.

The last answer would seem to infer constant speed (and velocity) provided a retarding or dissipating force (e.g. air resistance or friction) is not involved. Such would be the case in a vacuum or on a frictionless surface.
 
Also, we have to assume uniform gravitational field.

Also, we have to assume uniform gravitational field.
i.e. that it doesn't change direction/orientation so as to affect motion perpendicular to the field.
