Which describes an object in projectile motion? Gravity acts to push the object sideways.
The object moves in a straight path.
The forward velocity of the object is 0 m/s.
The object’s inertia carries it forward.

gravity is something that makes things go up and down

Explanation:

the motion is sensible

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

the answer would be a
