Why does lifting one end of the track lead to constant acceleration?

Answer:- With the help of lifting one end of the track, a slope is shaped that produces a gravitational force acting on the objects sliding down the track. When tracks are elevated on one end, they basically act as inclined planes. If these tracks are made up of a single solid, this means that they will only have one worth for the coefficient of kinetic friction. Rendering to Newton’s second law, when a constant force functions on a heavy body, this causes it to accelerate, i.e., change velocity, at a constant rate. In the most rudimentary scenario, applying a force to a motionless object causes it to quicken in the direction of the force.
