Here's an experiment you can do at home to measure the drag coefficient for a falling object. How can i start the experiment if i don't have something to compare with for i could do the experiment inside a place (vacuum) where there is no air resistance and compare my result where there is some but that is not possible i don't want any answers, just some advice to steer me in the right direction. Today we made simple air foils and explored this air resistance stem activity as a a quick after camp project homemade stem activities and science since you want to conduct an experiment here, you will want to have some trial runs with different air foils to start, you want a control test which will just. During the discussion, you will be able to introduce and define the terms upthrust, drag, air resistance, lift and terminal velocity a corresponding upward force of the air on the wing (newton's third law) this is the force we call 'lift' students will now be familiar with drag, thrust, lift, upthrust and weight student experiment. It depends on how much trouble you want to go to a japanese colleague and former boss actually worked for several years on creating a high-tech galileo experiment as his day-job at the japanese national research laboratory of metrology to get 1. Topics covered: interpreting distance, speed and time graphs, acceleration caused by forces investigating the effect of air resistance on acceleration in this experiment you can attach accessories to the dynakar in order to increase the air resistance and explore the relationship with acceleration what you will investigate.
Conclusion by carrying out this experiment i have learnt that surface area plays a great part on an object being dropped from a distance, even if the mass of the object is the same the greater the surface area of the object, the greater air resistance, this is because the more surface there is, the greater the number of particles.

In a famous demonstration, galileo supposedly dropped a heavy weight and a light weight from the top of the leaning tower of pisa to show that both weights fall at the same acceleration however, this rule is true only if there is no air resistance this demonstration lets you repeat galileo's experiment in a vacuum.
Repeat the experiment with a feather and a tennis ball what do you notice the tennis ball should hit the ground first why the force of gravity acting on the ball and the feather is the same, but the feather experiences more air resistance what would happen if you tried it in a vacuum astronaut david scott tried it out - on. Air drag does not depend alone on the surface area of the object, but its value of mass/surface area if you can increase the surface area of the object while keeping it's mass the same, it will influence the air drag on it but if you increase the surface area while also increasing the mass, it will go unchanged. The use of air resistance to slow down a fall can be dated back to 90 bc according to chinese historian si ma chian, a legend described an emperor using two bamboo hopefully this experiment and the others help your students understand and even better, get excited about gravity and air resistance.
A2 physics coursework 1 what affects the range of a trebuchet for simplicity i will assume that air resistance is negligible, so that the only force acting on the projectile after it leaves the swing effect is that the projectile will follow a parabolic trajectory through the air when the trebuchet launches the. But why do all objects free fall at the same rate of acceleration regardless of their mass is it because they all weigh the same because they all have the same gravity because the air resistance is the same for each why these questions will be explored in this section of lesson 3 in addition to an exploration of free. The measured heights though were not very accurate because i dropped the parachute in an open area under various different heights wind played a huge role in affecting some of the trials and i had to perform the experiment many times in order for the air resistance force be equal to the gravitational.
