tennis
I would say tennisball because it has less mass inside it.
Tennis has a longer history than golf. The history of tennis, or variations of what would become tennis, dates back to the 12th century. Golf can be traced back to the 15th century.

Grass of course! Grass is more solid than dirt.
are you joking or.... sigh.....a baseball.

The kinetic energy of an object depends on both its mass and velocity, as described by the formula KE = 0.5 * m * v². While a tennis ball is generally heavier than a table tennis ball, it can also be hit with greater speed, resulting in higher kinetic energy. Therefore, in most scenarios, the tennis ball would have greater kinetic energy than the table tennis ball due to its larger mass and higher velocity during play.

Hot. Personal experiments have shown that temperatures below 25°C make the ball bounce less. From 25°C and upwards there aren't any greater changes in height of bounce. The balls bounce almost the same.
Because a baseball is smaller you could hit it farther. This is because with less surface area, there is less friction action on the ball. With less friction acting on the ball, it means less "stuff" is holding the ball back from traveling farther, the baseball can physical travel farther than a softball.
In general, yes, but the mass/volume ratios and the surface finishes are different, so the motion would be somewhat more or less pronounced.
Measuring the average kinetic energy of all particles in a baseball would provide information about the temperature of the baseball. The kinetic energy of particles is directly proportional to temperature, so a higher average kinetic energy would indicate a higher temperature.
