The earth never reverses direction, nor does any other planet.
The APPARENT reversal of direction of some other planets, as seen from earth, is called retrograde motion.
By definition, friction is opposite of the direction of motion.
Retrograde motion is an optical illusion where a planet appears to move backwards in its orbit when viewed from Earth. This occurs due to the difference in orbital speeds between Earth and the observed planet. Modern understanding attributes retrograde motion to the relative motion and positions of the Earth and the observed planet as they orbit the Sun.
A planet's backward motion in the sky is called retrograde motion. This occurs when a planet appears to move in the opposite direction in the night sky compared to its usual eastward movement.
retrograde motion
The direction of friction is opposite to the direction of motion. This means that when an object is moving in one direction, the friction force is acting in the opposite direction, trying to slow down or stop the object.
When an object changes direction in its motion, its velocity changes, and if the object is accelerating, its acceleration will also change direction. This change in direction is due to the application of a force in the opposite direction. The object's kinetic energy may also change as a result of this change in direction.
The direction of the impulse vector is determined by the direction in which the force is applied to an object. It is always along the line of action of the force. The impulse vector points in the same direction as the force on the object and causes a change in the object's momentum in that direction.
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
Any change in the speed or direction of a moving object is called acceleration. It can be caused by applying a force in the direction of motion (speeding up), opposite to the direction of motion (slowing down), or perpendicular to the direction of motion (changing direction).
Speed and direction is called velocity.
Speed and direction is called velocity.
Displacement is at its maximum when an object changes direction, reaching the farthest point from its starting position. Velocity is equal to zero at the moment when an object changes direction, either at the peak of motion in a vertical direction or at the points where an object reverses its direction horizontally.
Well, it's often referred to as the direction of propagation of the wave.
The direction of melody is simply called it's motion.
