AI Thread Summary
To simulate a robot moving in water, key forces to consider include gravitational force acting downward, buoyancy acting upward, viscous drag opposing motion, and the force exerted by the robot to propel itself. A simple model can be developed by calculating these forces to determine the net force acting on the robot during movement. It is important to note that turbulence is neglected in this scenario, as the water is assumed to be static. Understanding these forces will enable accurate simulation of the robot's motion in water. This foundational knowledge is crucial for effective modeling and simulation of aquatic robotic systems.

I am trying to simulate a robot moving in water.
I need to determine exactly what forces will act on the robot from the water (bouyancy is obvious, and understood).
I need a simple model that will enable me to compute what force the water will exert on the robot, when one of its parts move.
(I neglect turbulence in the water. Also, the water is static, not flowing!)
Thanks.

The forces acting on you robot will be:
1. Gravitational (vertically downward)
2. Bouyancy (vertically upwards)
3. Viscous drag ( opposite to the direction of motion)
4. Force, your robot will apply to move.
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Effect of mass on the acceleration of an elastic pendulum?'

I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?

Thread 'Inclined treadmills and Galilean Invariance'

This has been discussed many times on PF, and will likely come up again, so the video might come handy.
