3. a feather and a brick are both dropped from a height of 10 meters. how fast do these objects accelerate towards the earth? explain how you know.\nstamp: what does it mean for an object to be accelerating?\nan object is accelerating when its velocity is changing. this means that the object is not in equilibrium because it is experiencing unbalanced forces (velocity is not constant).\nvelocity lab experiment\nwork with your group to follow the experiment procedure. collect and organize all data for your lab. at the end of this time we will use your data to calculate impact velocity for both heights.\neffect of height on object freefall time\nheight (meters) trial freefall time (seconds)\n1.0 meters 1\n2\n3\n4\n5\naverage (sum)/(number of values)\n2.0 meters 1\n2\n3\n4\n5
Answer
Explanation:
Step1: Recall the concept of free - fall acceleration
In the absence of air resistance, all objects near the Earth's surface accelerate towards the Earth at a constant rate. This is known as the acceleration due to gravity.
Step2: State the value of acceleration due to gravity
The acceleration due to gravity near the Earth's surface is approximately (g = 9.8\space m/s^{2}). This value is the same for all objects in free - fall (neglecting air resistance), regardless of their mass (like the feather and the brick in this case).
Answer:
Both the feather and the brick accelerate towards the Earth at approximately (9.8\space m/s^{2}). This is because, in the absence of air resistance (assuming ideal free - fall conditions), the acceleration due to gravity (g) near the Earth's surface is a constant value ((g\approx9.8\space m/s^{2})) and acts equally on all objects, regardless of their mass or type.
