What happen to the speed and the direction of motion of a ball rolling down an inclined plane
Answers
The speed of the ball increases gradually and the motion of the ball is a combination of Rotation and Translatory motion.
The increase in the speed of the ball would be directly proportional to the steepness of the incline or the angle θ it is making with the horizontal because as we increase the angle θ the vertical component of the acceleration i.e. sin θ increases.
The motion of the ball would be both in rotation as well as translation motion as the ball is revolving around its own center of mass, so its rotatory motion and it is having displacement from one point to other, so it's translatory motion as well.
Answer:
The ball will slow down due to friction while moving across the level surface and it will speed up due to the parallel component of the weight vector while moving down the incline.
