It is because the skier (when stationary) is moving at the same speed as the Earth's rotation. The same effect is felt by passengers on a bus. When the bus suddenly starts off, the passengers are thrust back into their seats. When the bus suddenly stops, the passengers are thrust forwards in their seats. But, for most of the journey, when the bus is travelling at a steady speed, the passengers can relax in their seats and enjoy the journey.
gravity The force on each other is the same (action and reaction) The skier and the earth accelerate toward each other according to: acceleration = force / mass. But because the earth is so massive , (compared to the skier) its rate of acceleration is immeasurably small, as is the distance it travels. > This is only concerned with the vertical component of the skiers motion.
The stars usually don't move much, but earth moves a lot. Since star are in view from the earth at any sight direction, the earth rotating, and revolving gets the earth viewing different parts of space from different places. It moves gradually, so the star seem to move.
kinetic energy
A skier at the top of the mountain has potential energy, which is the energy stored in an object due to its position or state. As the skier moves downhill, potential energy is gradually converted into kinetic energy, the energy of motion.
A skier at the top of a hill would have potential energy due to their elevated position. This potential energy can be converted into kinetic energy as the skier moves downhill.
the earth rotates giving the illusion of the sun moving across the sky
the earth does not stay still the earth turns on its own axis, it also moves around the sun. the sky moves because the wind blows the clouds. did you now learn anything in science
The groups of stars whose positions seem to change as Earth moves are called constellations. These groupings of stars are a result of patterns that early astronomers and cultures identified in the sky. The apparent movement of constellations is due to Earth's rotation on its axis and its orbit around the Sun.
A person who moves through water could be a swimmer, a SCUBA diver, a surfer, a water skier, or maybe Aquaman.
bobsled
The skier at the top of the hill has potential energy, which is the energy an object has due to its position or state. As the skier moves downhill, potential energy is converted into kinetic energy, the energy of motion.
the earth moves faster than you or i can run the earth moves faster than the bullet from a gun
