What happens to the force by the person pushing the crate ( F applied ) as the frictional force increases? What can they do to change this force?

The material that keeps its new shape after it is stretched is called?

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?

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
