PYTHON HOMEWORK When an object is falling because of gravity, the following formula can be used ot determine the distance the object falls during a specific time period: d=1/2 g t^2 The variables in the formula are as follows: d is the distance in meters(m), g is the acceleration due to gravity, an and its value is 9.8 m/s^2, t is the time duration in seconds(s). Write a function named falling_distance() that accepts an object's falling duration(time) in seconds as...

When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...

Which of the following statements are true? Because the Earth has mass it produces gravity. There is no gravity at the space station I need to do work to move a satellite from lower to higher orbit. Because the force of gravity is a conservative force and because it acts as a centripetal force it does no work, the mechanical energy of Earth is conserved and it will not crush into the Sun. Since Moon has no air, there is...

There are four known fundamental forces of nature. They are called fundamental because our theories cannot simplify them further. It is believed that all the forces are really the same, but they manifest differently at the low energy density our universe currently has. At the origin of the universe, when it was the size of the Planck scale, the forces were unified. Build a table with the following information for each force: if gravity is equal to 1, the relative...
