Discussion Overview

The discussion revolves around the scenario of accelerating a four gram bullet using a power of 100,000 horsepower and seeks to determine the distance the bullet would travel in one second. The conversation touches on concepts of force, power, energy, and the relationship between them in the context of physics, with participants debating the implications of these concepts on the problem posed.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related
  • Debate/contested

Main Points Raised

  • Some participants clarify that force and power are distinct concepts, with power being related to energy over time rather than direct acceleration.
  • One participant suggests integrating power over one second to determine the energy change and subsequently find the bullet's velocity.
  • Another participant emphasizes the need to calculate distance as the product of velocity and time, indicating that the mathematical work is left to the original poster.
  • There is a contention regarding whether the original question is homework-related, with some participants asserting that it resembles a homework problem while others argue it is not.
  • Some participants encourage the original poster to learn basic physics definitions and concepts to clarify their questions and improve understanding.
  • There is a suggestion that knowledge of algebra and kinetic energy equations could facilitate the calculation of final velocity and distance traveled.

Areas of Agreement / Disagreement

Participants generally disagree on the nature of the original question, with some viewing it as a straightforward physics problem while others challenge its formulation and clarity. There is no consensus on how to approach the problem due to differing interpretations of the concepts involved.

Contextual Notes

The discussion highlights limitations in the original question's clarity regarding the use of force versus power and the assumptions underlying the calculations of distance and velocity. There is also an indication that the original poster may lack a strong background in physics, which affects the discourse.

Hi,

Imagine there is a four gram bullet, but someone want to accelerate it with force or power equal to 100,000 horsepower. How far the distance will the lightweight bullet cover in a second?
 
Physics news on Phys.org
Are you accelerating the bullet with force or power? They're two different things, and only one of them causes acceleration.
Doing work on the bullet over time equivalent to 100000 horsepower will put energy into the bullet; if all of this energy becomes kinetic energy, you can integrate the power over 1 second to get the energy change, from which you can find velocity.
 
So, how much is the distance covered by the four gram bullet in a second?
 
The velocity multiplied by 1 second is your distance. The math is up to you.

Force and power are completely different things. Power doesn't cause acceleration, and forces aren't measured in horsepower, so your question makes no sense. You will have to think more carefully about exactly what you're trying to ask, and then when you know what you you want to ask you can ask it, and you'll get better more helpful answers.
 
This is a basic homework-like question, so we expect you to work it out like a homework problem. Since you might not have any physics background, I'll give some hints. Power is just the change in energy over time. What is the equation for kinetic energy? Since the velocity is not constant, you need to integrate the velocity to find the distance.
 
No, this is not a homework. I have no experiences in advanced mathematics, that's why I asking this question.
 
But you can easily learn basic definitions so your questions make sense.
 
If you know a little algebra and the equation for kinetic energy, you can calculate the final velocity. If you know a little calculus, you can calculate the distance traveled. Unless you really need the answer right away, you should take the opportunity to learn how to do it.
