Acceleration in 2D Video Lessons

Concept

Problem: I did an experiment with the motion detector using the lab pro and the logger pro. I want to know: "Why does lifting one end of the track lead to constant acceleration?" and "'what determines how much acceleration there is?"

FREE Expert Solution

Lifting one end of the track divides the weight into two components — mgcosθ and mgsinθ.

The weight acts vertically downwards.

The Normal force acts perpendicularly to the slope with magnitude equal to mgcosθ

The kinetic friction force acts parallel to the surface in the direction against the motion.

Force due to a weight component (mgsinθ) acts parallel to the surface directed downslope.
