On Earth, a free-falling object accelerates at 32 feet per second. This means that after two seconds the object is falling at 64 feet per second, and after three seconds it's travelling at 96 feet per second, and so on.
Know MoreThe object's velocity continues to increase at the same rate until it reaches its terminal velocity, which is when air resistance equals the force of gravity. When the terminal velocity is reached, a free-falling object can no longer accelerate. In a vacuum, a feather falls at the same rate as a hammer because there isn't any air resistance to slow either object down.
Learn more about Motion & MechanicsThe path taken by a flying object in motion on the surface of the Earth is called a parabola. A parabola is a symmetrical arc, and the trajectory of flying objects with negligible air resistance in a gravitational field, as on the surface of the Earth, follows this path.
Full Answer >Calculating how many feet are in something requires two steps: measuring the object and then converting the measurement into feet. The measurement can be made from any metric or English measurement of length, but the conversion requires knowing the ratio of the particular unit of measurement used to one foot.
Full Answer >Objects fall at the same velocity regardless of their weight, if gravity is the only force acting upon them. In a vacuum, where air resistance has been eliminated, a bowling ball and a feather fall at the same speed.
Full Answer >There are a couple of ways to protect an egg from a fall. For this method, you need an egg, five small ziplock bags, one large ziplock bag and a box or two of Rice Krispies cereal.
