Because ----
Plains tend to be more fertile and have better access to water sources, making them suitable for agriculture which can support larger populations. Additionally, the flat terrain of plains makes it easier to build infrastructure and transportation networks, attracting more people to settle in these areas. This increased population density on plains can also create economic advantages and opportunities that further contribute to their high population.

The value of the force of gravity (standard value of g=9.8 m per second squared) on hills is less than at the plains so the weight of tennis ball at hills is less than at plains. In other words, the force with which the earth attracts the ball on hills will be less than at plains.
Landforms
The Black Hills
Plains are just like open fields they just have no hills. I hope this helps you with your answer
The four major land regions of South Dakota are the Drift Prairie, the Disected Till Plains, the Great Plains, and the Black Hills. Almost 75% of South Dakota is covered by the Great Plains. Much of the Great Plains in South Dakota consist of rolling hills, plains, canyons, and buttes. The Missouri River runs through the center of South Dakota. The Black Hills are a low range of mountains. The Dissected Till Plains are an area of rolling hills dissected by many streams. The Drift Prairie is an area of low hills and glacial lakes.
