When a man gets out of a moving bus, he needs to run in the same direction as the bus for a certain distance because of inertia. The man and the bus are both moving at the same speed, so by running in the same direction, he can match the speed of the bus and reduce the relative speed between himself and the bus, making it safer to come to a stop. Running in the opposite direction could result in him falling or injuring himself.
Work. The object doesn't have to be moving in the same direction as the force.If I'm pushing north and the object is moving northeast, then it has a componentof motion in the direction of my force, and I do work.
Velocity is the measure of speed in a certain direction. It is a vector quantity that includes both the speed of an object and the direction in which it is moving.
Speed in a certain direction refers to the rate at which an object is moving in that particular direction. It is a scalar quantity that does not take into account the object's change in direction, only how fast it is moving in a specific path.
Velocity can be negative in certain situations when an object is moving in the opposite direction of the chosen positive direction. This means that the object is moving in the negative direction along the chosen axis, resulting in a negative velocity value.
There is no such thing as an amount of force needed to move a certain distance or a certain direction. Asteroids, comets, moons, and planets have been moving trillions of miles through space for billions of years with either no force on them at all, or no force in the direction they're moving. You may have heard of Newton's First Law. It says that an object with no forces acting on it keeps moving in a straight line at a constant speed, which is kind of another good way of saying that it can move as far as you want it to with no force on it.
moving a point or shape etc a distance in a certain direction
If you have no velocity, then you aren't moving.

velocity (distance/time)
There is no such thing as an amount of force needed to move a certain distance or a certain direction. Asteroids, comets, moons, and planets have been moving trillions of miles through space for billions of years with either no force on them at all, or no force in the direction they're moving.

The relationship between the velocity of an object and the time it takes to travel a certain distance is that the higher the velocity, the shorter the time it takes to cover the distance. This is because velocity is the speed of an object in a specific direction, so a higher velocity means the object is moving faster and can cover the distance in less time.
Speed and direction together describe velocity, which is a vector quantity that includes both the rate at which an object is moving (speed) and the direction in which it is moving. Velocity measures how fast an object is moving in a specific direction.
Wavelength is the distance from one molecule to the nearest molecule occupying a similar position and moving in the same direction.
