Why does a ball rolled along a horizontal surface maintain a constant speed?

A ball rolled along a horizontal surface maintains a constant speed because there is no external force acting on it to change its velocity. The absence of friction and air resistance allows the ball to continue moving at a steady pace.


What is the horizontal acceleration of a ball being rolled off of a cliff?

The horizontal acceleration of a ball rolling off a cliff is typically considered to be zero, assuming air resistance is neglected. The force of gravity acting vertically downward does not contribute to horizontal acceleration, as the ball falls vertically due to gravity while maintaining its initial horizontal velocity.


Why does a ball come to stop when it is rolled across the floor?

A ball comes to a stop when it is rolled across the floor due to various factors such as friction between the ball and the floor, air resistance, and the transfer of kinetic energy into other forms of energy like heat and sound. These factors act to slow down the ball's motion until it eventually stops.


What weighs more rolled paper or unrolled?

Rolled paper weighs more than unrolled paper because when paper is rolled, it becomes more compact and dense. The volume of the paper remains the same, but the weight is distributed differently.


What has a greater volume a piece of paper rolled into a cylinder lengthwise or a piece of paper rolled into a cylinder widthwise?

A piece of paper rolled into a cylinder lengthwise would have a greater volume because it would have a larger radius compared to one rolled into a cylinder widthwise. The volume of a cylinder is maximized when the radius is maximized, which occurs when the paper is rolled lengthwise.

In the 5G position for welding pipe the pipe must?

The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom). The pipe must be fixed (not rolled) in the horizontal position.
