What is the difference between a course and a heading?
Heading is the direction that the vessel is pointing. If there is no crosswind or crosscurrent it will also be identical to the course. The course is the actual path that is described by the vessel through the medium it travels. Again, if there is no crosswind and no crosscurrent the course would be identical to the heading.

What is the difference between magnetic heading and true heading?
Magnetic heading is your direction relative to magnetic north, read from your magnetic compass. True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart.
How do you read a heading?
Heading is typically based on compass directions, so 0° (or 360°) indicates a direction toward true North, 90° indicates a direction toward true East, 180° is true South, and 270° is true West.
What is the difference between roller bearing and ball bearing?
A roller bearing is a cylindrical unit that is used to provide low-friction movement for a bushing or bearing block. A ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The real difference has to do with the contact surface between the bearing and the rail.Feb 28, 2018

What is the difference between a bearing and a heading?
The difference is due to cross winds. Let’s say that you want to go true north, but there is a wind from the east. So your bearing would be 360, but your heading might be, depending on your speed and wind speed, 007. Besides bearing and heading there is a third one, track. Your bearing is 360 and your heading is 007, but your calculations were wrong so maybe your track is 002.
What is bearing in physics?
Typically bearing is a relation to another object using YOUR bow or nose as zero degrees on a 360 degree scale. Heading is relationship using rhe bow or nose to either magnetic or true north based on a compass reading. Course is the relation to the direction of travel in a line related to either to true or magnetic north for example: you have to point the nose or bow off of the direction you want to go to make up for air or sea currents trying to push you from the side of you craft. That could be a little push or big push so you have to crab off heading. You are traveling to you destination a

How to read a course bearing?
The course bearing is the bearing you’ll follow to stay on a leg of a course. For example, the course bearing from “B” to “C” is 71 degrees true and 75 degrees magnetic. The course bearing from “C” to “D” is 30 degrees true and 34 degrees magnetic. To follow a bearing, point your kayak so your compass reads the course bearing and then paddle while keeping your compass pointed at that bearing. When marking a course bearing on your chart, you can mark true, magnetic or both. Stay consistent or label the bearings. You can also mark a back bearing, which is the bearing to take if traveling the course in the opposite direction. The back bearing is always 180 degrees away from your bearing. While marking bearings on your chart, adding distance saves time later.
How to follow a bearing on a kayak?
To follow a bearing, point your kayak so your compass reads the course bearing and then paddle while keeping your compass pointed at that bearing. When marking a course bearing on your chart, you can mark true, magnetic or both. Stay consistent or label the bearings.

Heading
Track
- Track is the easiest of these four to understand in my mind,because it simply refers to how you are actually tracking over the ground. Whennavigating in the air, your track is really all that matters in terms ofgetting to where you want to go. If you need to go northeast to yourdestination, and have a significant wind from the west, your heading might beto the north in order to achieve a tr…
Bearing
- Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”. This simply means that off of the VOR they are tracking on the 090 radial outbound from the station. In relation to th…
Course
- Course is very similar to bearing in that it’s the desireddirection for your route of flight. If you are going directly from one airportto the other, your course and bearing will be the same along the route of flight.If you are flying from an airport to a VOR to another airport, your course willchange in each leg, as will your bearing.
Example
- For this example we’re going to work backwards through the above mentioned directions. Assume you are departing an airport and your destination is directly eastbound. When you take off the course between the departing airport and destination airport is 090. In this instance the bearing of the destination airport off of your departing airport is also 090. This is also the direction you wan…
Does A GPS Use True Or Magnetic Heading?
- The above example assumes you are using the compass in yourairplane (hence why it requires so many steps to calibrate the differencebetween your true course all the way down to your actual compass heading). Butwhat about a GPS? By definition it’s not using earth’s magnetic fields as a wayof navigation, but rather positioning information provided by satellites. So ifit shows your “de…
