In terms of bearings. North is at a bearing of 000 (always given as a 3-digit number). Move clockwise to East = 090, South = 180, West = 270. Intermediate angles as appropriate degrees.
asking and giving direction
right angle
Yes, changing the angle of a vector will result in a change in its direction. The magnitude of the vector remains the same, but the direction it points in will be different.
Because at every point IN the rainbow, the angle between the direction to the sun and the direction to your eye has to be the same angle. The only bunch of points that can satisfy that requirement is a bunch of points that are all on the same circle.
An angle is positive when it is measured in a counter-clockwise direction. It is negative when it is measured in a clock-wise direction.
An angle is a measure of turn. the amount of turn is the magnitude, measured in degrees, and direction of turn can be clockwise or anti-clockwise. A positive angle turns in an anti-clockwise direction while a negative angle turns in a clockwise direction.
either 00 or 1800A straight angle is an "angle" that doesn't affect the direction of a line. A 00angle sends the line in the opposite direction.
The answer depends on the form in which the direction is given. On the coordinate plane, the direction given by the polar coordinates is the angle made with the positive direction of the x-axis.
When you apply force at an angle to the direction of movement, only the component of the force in the direction of movement does work. The work done is calculated using the cosine of the angle between the force and the direction of movement. The component of the force perpendicular to the direction of movement does not contribute to the work done.
The 'normal' direction is the direction perpendicular to a surface. Think of a stick with one end of it glued to a mirror. When a beam of light or a tennis ball hits the surface, the 'angle of incidence' is the angle between the normal and the direction the ball came from. The 'angle of reflection' is the angle between the normal and the direction the ball will take after the bounce. The angle of reflection will be equal to the angle of incidence. Knowing this, you can always place your bank shot exactly where you want it to go after the bounce.
The angle between the airplane's wing and the direction of airflow is called the angle of attack. This angle is important for generating lift and controlling the aircraft's flight.
The direction of the applied force affects the amount of force that is doing work because work is the component of force that acts in the direction of the displacement. When the applied force is in the same direction as the displacement, all of it does work. If the force is at an angle to the displacement, only the component of the force parallel to the displacement does work.
