Bad form. A skilfully thrown bowling ball travels on a curve.
The magnitude of the velocity change is the same in both cases.
Three consecutive strikes in bowling scores 30 points in the frame that the first strike occurred. A score for a strike is 10 plus the next two balls thrown. If a strike is followed by a strike and then an 8 on the first ball of the third frame then the first strike is worth just 28 points.
Rolled? Thrown? How heavy of a bowling ball? And the speed of a ball depends on how hard a person throws it. It is hard to answer such a general question.
The bowling ball is a solid material and is intended to be tossed and rolled while the basketball is filled with air and is intended to be thrown, caught, and bounced. Because - a basketball is intended to be thrown from one person to another - a bowling ball is intended to be aimed at solid wooden pins !
The brown ball is the 4 ball and worth 4 points.
If you are referencing tenpin bowling, you throw 2 balls each frame for the first 9 frames, unless your first ball in a frame is a strike, to which only the one ball is thrown. In the 10th frame, 3 balls are thrown unless a strike is not made with the first ball or a spare is not made with the 2nd ball.
10 plus your next ball
The blue ball is worth 5 points in snooker.
The green ball is worth three points in snooker.
