Homework Help Overview

The problem involves calculating the power of a motor that can lift a force of 600 N in one minute. The context suggests a focus on the relationship between force, work, and power, particularly in a physics education setting.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the necessity of distance in calculating power, with one noting that power is derived from work, which requires both force and distance. Questions arise about the implications of missing distance in the calculation.

Discussion Status

Some participants have provided clarifications regarding the relationship between force, work, and power, highlighting the missing information necessary for a complete calculation. The discussion reflects a mix of interpretations regarding the problem's requirements.

Contextual Notes

The problem is sourced from a GCSE revision book, which may imply specific educational constraints or expectations regarding the level of detail provided in the question.

Calculate the power of a motor that can lift 600 N in 1 Minute

Homework Equations

The Attempt at a Solution



I've been asked to help a friends daughter with this question because I work in a Lab, unfortunately I'm a biologist working in a chemistry lab so I'm struggling![/B]

I assumed that distance was required to work out power:

power (W) = N x Distance (m)

Time (s)

Am I missing something entirely?

Thanks in advance!

Hello AP, welcome to PF :smile: !

Yes, there is something missing: 600 N is a force. Work (energy) is force times distance. Power is work per time. So the calculation

Power = Force x distance / time
can't be made: the distance is missing.
 
Thanks very much!

This problem is in a GCSE revision book, and that is the problem word for word. At least it has got me interested in physics again, thanks for the welcome.
 
Strange. You can imagine it takes a bit more power to lift 600 N over 100 m in one minute than over 1 meter ...
