Why do you have to run a certain distance in the direction of motion of train while stepping out of the moving train?

Before you step off of the train, your body is moving past the walkway at the same speed as the train.
Its natural tendency is to keep moving in the same direction at the same speed, but once you step onto the walkway, that means your body wants to move along the walkway at the speed of the train. You have to slow your body down gradually, which you can only do by deftly manipulating the contact between the walkway and your feet.
If you stepped off and expected to just stand there, your feet might stay on the walkway, but the rest of you still needs to keep going at the speed of the train, resulting in a phenomenon known as "falling down".

How can you find the direction of motion from a distance x axis and time y axis graph?
You can't. Such a graph is only appropriate for motion in a single dimension.
How does the direction of friction compare to the direction of Motion?
By definition, friction is opposite of the direction of motion.
How does the direction of friction compare to the direct motion?
The direction of the force of friction is opposite of the direction of the motion.
What feature of a distance time graph represents the direction of motion?
the velocity and acceleration Not really. The direction is implied by the description of the distance axis, so as you go to the right on the graph it represents greater distance from the point which you have chosen to represent your point of reference. So you could define it for example as the distance east of your start point, or the distance north from your start point, or just the distance in any direction etc. If your description does not specify a direction, then all you can say is how far from the start you are, with no other information on compass direction etc.
What is vilosity?
You find the velocity by distance divide by speed
Why do we have to run a certain distance in the direction of motion of atrain while stepping out?
You do not. You wait until the train stops and then step out without needing to run.
What occurs when force is applied over a certain distance and motion is in the same direction as the force?
There is exergy. Energy is given out by the motion.
Occurs when force is applied over a certain distance and motion is in the same direction as the force?
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.
What does the slope on a distance-time motion graph indicate?
It shows the component of velocity in a radial direction. Any motion in a transverse direction is ignored.
Which physical quantity is measured by the area under velocity time graph?
The distance covered in the direction of motion or the opposite direction. Distance covered in the transverse direction is not included.
When an object accelerate what can it do?
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.
How do you calculate the amount of work a certain amount of force exerts?
Multiply the magnitude of the force component in the direction of motion by the distance through which it moves. The product is the work done by the force.
Motion is measured by distance divided by time in given direction is called ...?
Velocity.
What are the situations in which work is not done?
There are 3 conditions for work. First, there must be force. Second, when you apply a certain amount force to an object, it must move a certain distance. lastly, the force that you applied and the direction of the motion must be parallel. If you applied force tot eh right, then the object must move to the right. When you lift a book and then you walk around, no work is done. The direction of the force of your hand is going upwards while the direction of your motion is either left or right. Therefore the force applied and the distance moved are perpendicular.
What is a streetstepper?
A bike with no seat that uses a stepping motion to generate forward motion.
What is impending motion?
I'm pretty sure it means the motion or movement that is going to happen. So, if you apply force in a direction to a box, the impending motion will be sliding or tipping in the direction of force depending on certain coefficients of friction.
What occurs when force is applied over a curtain distance and motion is in the same direction as the force?
earthquakes
