Can Commercial Aircraft Fly a Curved Route Instead of in a Straight Line? 1

Several good answers but they could use a little assist. As John Cheshire noted, on a globe, the shortest distance between two points is indeed a straight line as the earth is a spheroid. That 'straight line" is the edge of a circle, the center of which is at the center of the earth and is called a 'great circle. " And indeed, both air mariners (pilots) and mariners prefer to travel the shortest distance possible to save time and money.Maps (or charts as we nautical types call them) are 2D representations of the earth's 3D geography. The most common type of chart is called a Mercator projection. The way to think about how these are constructed is to imagine a rectangular sheet of paper wrapped around a globe with the middle of the paper touching the equator. Then imagine that at the center of the globe is a light that can shine through the skin of the globe and onto the paper, where you can trace the geography. Because the distance from the center of the globe to the paper is very close near the equator, you get a pretty good representation, but the closer to the poles you get, because the distance from the center to the globe surface becomes significantly less than the distance to the paper, distortion appears. This is why Greenland looks so big on most maps, but if you look at it on a globe you see that it is really much smaller.When you look at the map on the airplane with a long distance route, the curve in the route is due to this distortion in the map projection.So how do the pilots (or mariners at sea) manage this? Well, there is a special type of chart for planning long distance voyages called a 'Great Circle Chart" which is a Gnomonic projection chart. On this chart, straight lines are great circles. The navigator will pick off the latitude and longitude of points every 200 miles or so and transcribe them onto a mercator projection. This will create a series of straight lines on a typical Mercator projection. And those are the courses that aircraft or ships will steer on long distance voyages. For short voyages the savings is negligible and is often overcome by other considerations such as air corridors (shipping lanes) and the best way to approach an airport (or port)

What is the acceleration due to gravity on Earth when an object is moving in a straight line?

It will always act downward to earth. Because of acceleration due to gravity we have weight which is 9.8 times of the mass of your body. If you have 10 kg mass then your weight is nearly 100 newton. As you are moving in straight line your leg gets up and down against the weight of your body.

Drawing straight line between two points

I do not really understand what your explanation of what goes wrong, but it's just a matter of choosing the proper coordinates I suppose. The slope of your blue line is -1, so you can for example start the line at (-1,2) instead of (0,1), and end it at (2,-1) instead of (1,0)

Why does a spacecraft use a curved orbit to go to its destination, instead of traveling in a straight line?

This field of study is called Orbital Mechanics. An object in orbit behaves in ways that are counterintuitive if you do not realize fully what is going on. The orbit you've drawn is almost impossible to achieve. When a spacecraft travels from Earth to Mars, it orbits the Sun. Anything it does is influenced by the gravitational attraction of the Sun. When you leave Earth and you accelerate, you wo not fly in a straight line: your path will be curved because the Sun keeps pulling on you. This is the curve you see in the MOM trajectory. If you really want a trajectory that is straight, you will have to expend lots of fuel counteracting the Sun's pull. This takes much more fuel than a curved orbit.
