It took less time for the marble to reach the table as the angle increased. As the acceleration decreases, the time increases.
The marble will travel faster when the height of the inclined plane was raised.
According to the concept of force in an inclined plane where F = mg sinθ, the force is directly proportional to the sine of the angle.
Raising the height to the inclined planed will create an additional angle along its horizontal. Thus, applying its force using Newton's second law
where F = ma, the calculated force will result in greater acceleration and speed.
Therefore, raising the inclined plane increases the speed of the marble rolling down the inclined plane, and the greater distance it will travel.
