I was thinking off building a drone and I was just curious about what the amount of thrust we need to be in order to hover based on weight

Sorry if this I said stupid question but I don't know. So is 1 Newton of force required to hover 1 gram?ZapperZ said:I'm scratching my head here quite a bit.
"Thrust" is a force. You know the weight (mg) of the object. Shouldn't the thrust be at least equal to the weight?
Zz.
No, it's 9.8 Newtons per kilogram at Earth's surface.ARC123 said:Sorry if this I said stupid question but I don't know. So is 1 Newton of force required to hover 1 gram?
No the answer you gave me is what I was looking for I just couldn't find how much it would take to lift 1 gram. I thought it would be around .098 or something like that. But I was wondering if there was a formula so that i just plug in the mass and I get the thrust in Newtons.russ_watters said:No, it's 9.8 Newtons per kilogram at Earth's surface.
But is this really the question you want to ask or are you really needing to figure out how to generate the thrust?
So then to calculate something hovering would acceleration be 9.8 and mass always kilograms?Blibbler said:F=ma
The formula to calculate the amount of force needed to lift/hover an object is F = m x g, where F is the force in Newtons, m is the mass of the object in kilograms, and g is the acceleration due to gravity (9.8 m/s^2).
The mass of the object can be determined by weighing it using a scale or by using the density formula, where density = mass/volume. The volume can be measured using a ruler or by calculating the volume of a regular-shaped object using its dimensions.
The acceleration due to gravity is a constant value of 9.8 m/s^2, which represents the rate at which objects accelerate towards the Earth's surface due to the force of gravity.
Yes, the altitude or location can affect the calculation as the acceleration due to gravity can vary slightly depending on the altitude and location on Earth. However, for most practical purposes, this variation is negligible and the standard value of 9.8 m/s^2 can be used.
The angle or direction of lift does not affect the overall calculation, as the force required to lift an object is dependent on its mass and the acceleration due to gravity, regardless of the angle or direction of lift. However, the angle or direction may affect the distribution of force needed to lift the object evenly.
