A ball rolled across a horizontal table moves at constant velocity.why?
The ball moves at a constant velocity because there are no external forces acting on it to change its speed or direction. The absence of any net force means there is no acceleration, allowing the ball to maintain a steady velocity. This state of motion is in accordance with Newton's First Law of Motion.
What happens when a ball is rolled on a rough surface?
When a ball is rolled on a rough surface, the friction between the ball and the surface causes the ball to slow down more quickly compared to when rolled on a smooth surface. This friction converts some of the kinetic energy of the ball into heat, resulting in the ball losing speed and coming to a stop sooner.
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 piece of paper fall more slowly when it's flat than when it's rolled up?
When a piece of paper is flat, air resistance acts on a larger surface area, slowing down its fall compared to when it's rolled up with less surface area exposed to air resistance. The rolled-up paper offers less resistance to air flow, causing it to fall faster.
When a marbel is rolled along a floor what force or forces cause it to slow down and stop?
Friction is the force that causes a marble to slow down and eventually stop when rolled along a floor. As the marble moves, it experiences opposing forces from the floor's surface, generating heat and slowing down the marble's motion.

What is the relationship between rolled distance and time taken?
If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.
What is the difference between a spiral perm and a loose perm?
spiral perm is rolled vertical and reg perm is rolled horizontal, I think.
What is the surface on which the ball is rolled in bowling?
Wood

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.

What planet had a small robot that rolled on its surface and took photos?
Mars

How fast must a ball be rolled along the surface of a 70cm high table so that when it rolls off the edge it will strike the floor at the same distance from the point directly below the edge of table?
(ignoring air resistance.) s = 0.7 metres take g = 9.82 (m / s) / s time to fall 0.7 metres, regardless of horizontal velocity, t = (sq. root (s / (0.5 * g))) = 0.3776 seconds so constant horizontal velocity required to travel 0.7 metres in 0.3776 seconds = 0.7 / 0.3776 = 1.854 metres / second
What is different between a rolled biscuits and a dropped biscuits?
A rolled biscuit is generally made by rolling the dough out on a surface and then cutting it into shape, a drop biscuit is made by spooning dough into a pan at the desired location.
Can rolled vinyl flooring be placed directly on top of leveling cement?
Yes as long as it is smooth and has no residue on the surface.
Is The ball rolled in the field or The ball rolled on the field correct?
If the field is a playing field, use on. If it is a field of corn, use in.
