The distance an object travels in a certain period of time without regard to direction is known as the object's displacement. Displacement is a vector quantity, meaning it has both magnitude (length) and direction. It is calculated by subtracting the initial position of the object from its final position. For example, if an object starts at position (2, 4) and ends at position (6, 8), the displacement would be (4, 4).
To put it simply, displacement is the distance an object travels in a certain period of time without regard to direction.
You do not. You wait until the train stops and then step out without needing to run.
A direct wave is a radio wave that travels directly through space without getting refracted by the ionosphere. In other words, it travels straight to the receiving antenna without being refracted.
Speed :)
Displacement is a vector quantity because it is has both magnitude and direction, while distance is a scalar quantity because it has only magnitude without direction.
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
VELOCITY IS THE SPEED AND DIRECTION IN WHICH SOMETHING MOVES. Velocity is the distance an object travels per unit of time, in a specific direction; velocity = distance / time, in a specific direction. The distance an object travels per unit of time, without regard to its direction of travel, is called Speed. If a vehicle travels around a curve in the road at a steady 50 kph, its Speed is staying the same but its Velocity is changing due to the change in its direction of travel. 50 kph northbound and 50 kph eastbound are the same Speeds but different Velocities.

A point that travels a distance without any angular deviation.
Speed describes the distance traveled by an object divided by the time in which the distance was traveled, if the direction is not specified.

As far as you like. For example it travels from the sun and gets through our atmosphere without much difficulty.
When an object accelerates it can change its speed or direction of motion. When it accelerates without changing its direction of motion, it can cover any distance in less time.

Propel an object into the air and measure the direction and distance it goes in. Or use the good old lick your finger and point it in the air until you find the direction of wind.
