Newton`s Laws of Motion
... If you hold a coin above your head while in a bus that is not moving, the coin will land at your feet when you drop it. Where will it land if the bus is moving in a straight line at constant speed? It will fall in the same spot as if the bus wasn't moving. This is because once the bus is moving at a ...

... A kite is hovering over the ground at the end of a straight 39-m line. The tension in the line has a magnitude of 14 N. Wind blowing on the kite exerts a force of 20 N, directed 67° above the horizontal. Note that the line attached to the kite is not oriented at an angle of 67° above the horizontal. ...
