In a expiriment to determine whether moment is conserved. You shoot a dart into a cart. You know both the mass of the dart and the distance between them. You also know the distance after the dart and cart joined together. The speed can be calculated both before and after the collision. Therefore you can calculate the momentum. What would be the dependant variable and independent variable be in this expiriment and what variables would be controlled ?

In this experiment, the dependent variable is the momentum, and the independent variable is the distance between the dart and the cart before the collision.

To determine if momentum is conserved, the momentum is calculated both before and after the collision. The distance between the dart and the cart before the collision is the independent variable because it is manipulated by the experimenter. By changing the distance, you can observe how it affects the momentum.

The variables that should be controlled in this experiment are the mass of the dart, the distance after the dart and cart joined together, and the speed calculated before and after the collision. Controlling these variables ensures that any changes in momentum can be attributed solely to the change in distance between the dart and the cart before the collision.
