I wanna give points so my question,
What is gravity?​

An invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. ... Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.

Explanation:

thx for the points :)

gravity is the force that attracts a body toward the center of the earth or toward any other physical body having mass.

Explanation:

the independent variable, or the one that is intentionally manipulated is the speed.
