What’s the relationship between air temperatures in air pressure at the equator

How is the gravitational force related to the distance between two objects?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass
