What happens if the string is released?
Answers
Answer:
Before the string is cut, the ball is being accelerated radially by the string towards the middle of the circle where the string is being held. The ball also has a velocity with constant magnitude but changing direction (due to the acceleration from the string). The direction of the velocity is tangent to the circular path and at a right angle to the acceleration vector.
Assuming no wind resistance, the only forces accelerating the ball are the radial acceleration from the string and gravity from earth. Once the string is cut, the only force acting on the ball is gravity.
If the ball was initially in horizontal circular motion then the ball will look as if it’s flying straight out when looked at from above, but will move in a downward sloped line if the ball is seen from the side.
What happens when the ball is cut when in vertical circular motion or any other angle or circular motion would be a good experiment to test out.
