When a ball appears to be rolling uphill, it is actually an optical illusion caused by the surrounding landscape. The slope of the hill and positioning of the ball can create this illusion. In reality, the ball is still rolling downhill, following the natural pull of gravity.
A ball travels faster uphill than downhill due to potential energy being converted to kinetic energy as it rolls downhill.
A ball slowing down as it rolls up a hill is an example of kinetic energy being converted into potential energy. As the ball moves uphill, it loses kinetic energy which is converted into gravitational potential energy due to its increased height. This conversion causes the ball to slow down.
As the ball rolls away from you, it will appear to decrease in size and eventually disappear from view due to its distance. The speed at which it moves away will determine how quickly it disappears.
The total displacement of the ball is the difference between the uphill distance (5 meters) and the downhill distance (9 meters), as displacement considers the final position relative to the initial position. Therefore, the displacement of the ball is 9 meters (downhill distance) - 5 meters (uphill distance) = 4 meters.
As the ball rolls across the floor, kinetic energy is converted to heat and sound due to friction between the ball and the surface. The ball's speed and direction may change depending on the surface it is rolling on and any obstacles in its path.
