So this is supposed to be a splash! When jumping off into water, it always seems to be more exhilarating to jump from high places rather than low areas! Today i learned from our Modern Galileo lab that if you were to fall from the same height as someone else, the rate at which you would fall would take the same amount of time, since the force of gravity is the same on both people. If you were for example jumping from a diving board and accelerated to travel up, you would speed up, slow down, stop for very short and travel in the opposite direction and with the help of gravity you would increase speed. You would accelerate down at the same rate you were forced up by the diving board. Gravity can be different though based on your location, which can cause some confusion when trying to graph and look at the constant acceleration. The acceleration or change in speed would decrease as you travelled up, but increase as you fell towards the water in uniform acceleration, which is equal increases in speed in equal intervals of time. Objects in freefall are objects under the influence of gravity, and acceleration=Ag and g is approximately 9.8m/s^2, which is always pulling downwards. Also, when we were doing the activity with the money and meter sticks falling, i figured out how to set up equations to easily solve for a certain variable, such as solving for time which is the square root of 2d/a in DAT equation. Then plug in the numbers to find the amount of time it would take! Distractions can obviously alter the times and decrease it because it takes longer for you to actually react to a situation when focussed on something else too!
This is very helpful for note taking on the free falling worksheet and i love the photo and the example.
