A ball moves faster on a sidewalk than on grass because the surface of the sidewalk is smoother and provides less resistance. The grass surface is uneven and offers more friction, which slows down the ball's movement.
It is easier to pull a wagon on the sidewalk than on grass because the wheels of the wagon roll more smoothly on a hard, flat surface like the sidewalk, compared to the uneven and soft surface of the grass which creates more resistance. The sidewalk provides a stable and firm base for the wheels to move efficiently.
When direct sunlight heats the sidewalk, the concrete material of the sidewalk absorbs the heat energy and warms up. This causes the molecules within the concrete to move faster, increasing the overall temperature of the sidewalk. The sidewalk then radiates this heat back into the environment, contributing to urban heat island effect.
Assuming the two balls have the same force applied to them, the 4-kg ball would move faster than the 6-kg ball due to its lower mass. According to Newton's Second Law, acceleration is inversely proportional to mass.
An hypothesis is a statement that is to be tested. So if you had two identical balls except one was a red ball and one was a blue ball, and you wanted to find out if the color of the ball influenced how far it could roll, one would arbitrarily select one of the balls, and make the Statement: "Given identical conditions, and identical balls except for color, a red ball will roll further than a blue ball." That is the hypothesis. (Now you need to develop "data quality objectives" under which you are going to control your data). In this case the rolling conditions are what is different, and so your hypothesis will reflect that. How do you suppose you can now reword your question as a statement that can be tested?
Adding oil to a ball will likely make it roll down a hill faster because the reduced friction between the ball and the surface will make it easier for the ball to move.
A ball rolls faster on grass or dirt because there is less friction compared to rough surfaces like concrete. The smoother texture of grass or dirt allows the ball to move more freely with less resistance, resulting in increased speed.

Move your leg faster
If the ball does not move and you are not in a hazard you do not get penalized however, you are not permitted "cut" the grass on the course.

Replace Toxic with another grass move.
The transfer of energy from your racket and the ground to the ball causes its particles to move faster, which causes heat.
When the ball encounters a blade of grass it causes the grass to move. The ball is effectively transferring its kinetic energy to the blade of grass. This transfer of energy occurs at each encounter with a blade of grass. Eventually the ball has transferred all of its energy to the grass and the ball stops. Since this transfer of energy is much less that 100% efficient, most of the energy from the ball is converted into heat via the resistance the grass has to bending, the grass sliding on neighboring blades of grass, the grass sliding on the ball itself, as well as complex interactions with the soil.
