1 Measuring thrust and predicting trajectory in model rocketry
... A linear interpolation is used to estimate the changing mass. -V(dm/dt) is computed using the velocity from the previous row and the change in mass from the previous row to the current row. The weight is mg. The drag force is computed using the velocity from the previous row. The acceleration is the ...

This happens because as you press on the master plunger, the movement first compresses the air, then it will move the slave plu ...

Therefore, any charged object attracted to a charged rubber rod (or repelled by a charged glass rod) must have a positive charge, and any charged object repelled by a charged ...
