A ball is dropped and its motion recorded It is found that the increase in speed is uniform for each second it falls Which inference do these observations support?

If the increase in speed is uniform, this means that the slope of the function of speed over time is constant. This means that acceleration is constant.

Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
What forces act on a ball once it is dropped?
Gravity brings it down. Air resistance will act the opposite way, this will be tiny at first but will increase with the balls velocity.
Explain where and why the energy is the greatest when a rock is dropped into a large puddle?
The key term here is "conservation of energy". Since energy can't increase or decrease over time, there is no moment when energy is "the greatest".
A 34.5-g gold is dropped into a graduated cylinder containing water by how many milliliters does the measured volume increase?
34.5/19.3=1.79mL (19.3 is the density of gold)
Does a balloon dropped from 6 feet make a bigger splash than a balloon dropped at 1 foot?
No a water balloon dropped from 1 foot
What pet does George Bush have?

How is mathematics essential to scientific communication?
Math is used to quantify scientific observations and predictions. Ie: how high will the ball bounce when dropped from 10 feet?
is the weather is cold Observation orInference?
"The weather is cold" is an observation because it is something you can feel. An inference is something you decide or think about an event after observing it. For example "The temperature must have dropped."
Ball is dropped from the top of a building One second later ball B is dropped from the same building as time progresses does the distance between them increase?
Yes.
