Answer: Polar air mass is the large mass of air formed over land or water in higher latitudes. They are characterized by cold air.
Tropical air mass is the large mass of air that is formed 25 degrees latitude of the equator. They are characterized by warm air.
Explanation:
Polar air mass is known for cold air near earth's surface. Polar air mass takes place in cold regions like Arctic region.
Unlike tropical air mass, polar air mass brings cold and dry air weather in winter season.
Continental polar mass takes place in cold, stable and low humid areas like subpolar land. Whereas, maritime polar air mass forms over oceans which are cool and located in polar region.
Tropical air mass is characterized by warm to hot air. But, as this air mass move away from their latitude of origin, they get cooled down. This phenomenon mostly result in precipitation and storms in Unites States. This also shows that tropical air mass contains moisture. They are usually prone to sudden changes.
Continental tropical air mass is produced over desert areas of the world during summer, when its hot. While, maritime tropical air mass is produced over tropical and subtropical oceans and seas in the world.

Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time,
