its a matter of common sense. a moving object and speed would equal a nasty fall and lack of control when falling
When you are inside a moving train or bus, you are moving at the same speed as that train or bus, and you have the same momentum, so even when you jump, and are no longer in contact with the floor, your existing momentum will carry you along with the vehicle, under normal circumstances. If you happen to jump at a time with the train or bus is changing the speed or direction of its travel, however, you will find that you do not stay in the same place, with respect to the train or bus. You need to have solid contact with the vehicle for its own changes of motion to alter your own motion.
a kangaroo can jump over a bus,they start from the back way
While you are moving, jump (wile moving). Once you land jump again (still moving same direction). Jump one more time exactly as you land (while moving in the same direction) to do the triple jump and get a little higher.
According to Newton's first law of motion, an object in a state of uniform motion will tend to stay in that state of motion until acted on by an external force. So, using this principle let's consider the case of a person on a bus. When you are standing on the bus, you are moving in the same direction with the same speed as the bus. When you jump up, the only force acting on you is gravity, which only affects your up-down motion. Assuming the bus is moving on a flat surface then, there are no forces acting on you in the direction of the motion of the bus to change your motion. Thus, you keep the same motion that the bus has, and you will stay in the same place relative to things inside the bus. There are situations in which this wont work! Consider, for example, what would happen if the bus made a sharp turn after you had jumped into the air. In this case, the some force has caused the bus to change direction, and so change its motion. However, since you are in the air, this force doesn't act on you. The result is that you will feel like you are moving relative to things inside the bus! Another related example of Newton's first law is when you jump on an elevator. If you jump just as the elevator is reaching the top, you will feel like you have jumped very high! This is because when you jump, you have the upward motion of the elevator, in addition to your jumping motion. When abraking force acts to slow the elevator down as it's reaching its destination, you avoid that force since you're in the air.
No
Get on it!Jump on.....
No, not until your schoolwork is done!
Your friend appears to be at rest on the moving bus because in the frame of reference of the bus, they are moving at the same speed as the bus. Therefore, they do not appear to be moving relative to the bus and seem to be at rest.
Until the stop sign on the side of the bus is pressed to the bus and the red lights behind it are off and the bus is moving forward again.
most likely if you are moving fast you will role the opposite direction that the car is moving. but the best bet is to never jump out of a moving car.
Press on dash and jump while moving.
Jumping Off a Cliff: An Unsafe PracticeJumping off a cliff is unsafe for the same reason jumping off the roof of a house is unsafe; the distance between where you jump from to where you land is most likely going to harm your body and might result in death.
