Astudent is conducting an expirement to determine how far a ball will roll down a ramp based on the angle of the incline what is the independent variable and dependent

Angle of inclination is the independent variable.

Distance covered by the rolling ball is the dependent variable.

Explanation:

An independent variable is the one whose variation is not dependent on the value of any other variable while dependent variable changes its value with a change in the independent variable.

In this experiment, angle of inclination (angle between a line and the x-axis) is an independent variable whereas the the distance covered by the rolling ball is a dependent variable which will vary with a change in angle of inclination.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
