Talk:Mass

the pendulum rocket fallacy affects hoverblades and thrusters. It's not just the direction of thrust that's important, but also any misalignment between the thrust vector and the center of mass. Hoverblades do provide constant downward thrust with their thrust vectoring, however if the center of mass is not in line with the thrust vector (i.e. if the robot is not a 'balanced' design or the robot is tipped up on a slope or obstacle) the pendulum rocket fallacy will amplify and increase instability. The hovercraft will be fine _most_ of the time, but when upset it can become completely unstable. --That which respawns you makes you stronger. (talk) 04:08, 4 November 2014 (UTC)

Difference between mass and weight.
Just wondering if this section should be rewritten, as it doesn't really explain the difference between mass and weight, as well as getting them slightly mixed up. Here is a proposed rewrite of the section that I quickly wrote up, obviously people can propose changes to both the existing section and proposed edit that I provide.

"Mass is a measure of how much matter an object contains, and is measured in kilograms (kg).

Weight is a force measured in Newtons (N), and describes how much force an object is experiencing due to gravity. Weight is calculated from multiplying the amount of mass an object has (in kilograms) to the gravity acceleration that object is experiencing, measured in metres per second per second (W = m·g).

This results in objects possibly weighing less on one planet and more on another. An example of this is objects on Mars for weighing 0.38 times less that it would on Earth, as Mars has weaker gravity (3.7 m/s²) when compared to Earth's (9.8 m/s²). For instance if an object weighs 10kg, on Earth it would weigh 98 Newtons, but on Mars it would weigh 38 Newtons.

Currently however all maps are placed on either Mars or GJ 1214b, both of which have the same strength of gravity. But Robocraft does support having planets with different gravity strengths, leading to the possibility of objects having a different weight from map to map. This point is supported by thrusters and armored helium having their lift denoted as a force, rather than the amount of mass they can lift, as they could move a lesser or larger amount of mass on different planets."
