Finding Force from Mass & Velocity: N = kg × m/s²

Click For Summary

Homework Help Overview

The discussion revolves around a problem involving the calculation of force given the mass of an object and its constant velocity. The subject area pertains to Newton's laws of motion, particularly the relationship between mass, velocity, and force.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the implications of constant velocity on net force, questioning whether a force can be calculated when acceleration is zero. There is a discussion about the interpretation of the relationship between force, mass, and acceleration as described by F=ma.

Discussion Status

The discussion is currently focused on the implications of constant velocity, with participants noting that if the velocity is constant, the net force is zero. There is an exploration of whether the problem might be misleading, but no consensus has been reached.

Contextual Notes

Participants are considering the definitions and implications of force in the context of constant velocity, with some suggesting that the problem may be a trick question. The original poster expresses confusion about how to derive force in Newtons under these conditions.

I have a problem that gives mass of object and the constant velocity. I need to find the force.

I know the answer needs to be in Newtons. So the weight is in "kg" and velocity is "m/s". I know that 1 N=1 kg x m/s^2. I am stuck on how to get the force into Newtons??

If the velocity and mass of the object are constant then there is no net force acting on the it.
 
Or could this be a trick question since a constant velocity has no acceleration and F=ma F=m(0) equals 0, so there is no force?
 
Yes. F_net = 0 when it is at a constant velocity. Simply because a = 0.
