How can I calculate the force of friction on a rocket launched at school?

[xCanx]

I have to find the force of friction against a rocket that we launched at school. How would I do that?

I know coefficient = Friction/Fn

I only have Fn, how do I find the frinction?

I'm really lost :(

I have Fg = 0.75 N, so that would be the work done against gravity, right?

So how would I use that to find the force of friction (air resistence in this case, since the rocket is thrust upward)

To find the force of friction on the rocket, you will need to first determine the coefficient of friction between the rocket and the surface it is sliding against. This coefficient can be found by dividing the force of friction by the normal force, as you mentioned. The normal force, or Fn, is the force exerted by the surface on the rocket in a direction perpendicular to the surface.

To find the force of friction, you will need to measure the normal force using a force sensor or scale. This can be done by placing the rocket on the surface and measuring the force exerted by the surface on the rocket. Once you have this measurement, you can use the coefficient of friction equation to calculate the force of friction.

It is important to note that the force of friction is dependent on the coefficient of friction and the normal force, so it is important to accurately measure both of these values. Additionally, the force of friction may vary depending on the surface the rocket is sliding on, so it is important to conduct multiple trials to ensure accuracy.

I understand that this process may seem confusing, but don't hesitate to seek help from a teacher or classmate who may have more experience with these calculations. Good luck with your project!
