a student is conducting experiments with a block of wood. in experiment 1, the student pulls the block of wood with a constant force of 10 N along a horizontal surface.

In this experiment, you will use a track, a toy car, and some washers to explore newton’s first two laws of motion. you will make observations and collect data regarding the motion of these objects. in the space below, write a general scientific question that you will answer by doing this experiment.
