What does the speed of a satellite depend on when orbiting earth?
The speed of a satellite orbiting Earth primarily depends on its altitude and the gravitational pull of the Earth. According to Kepler's laws of planetary motion, a satellite in a lower orbit must travel faster to counteract the stronger gravitational force compared to one in a higher orbit. The relationship can be expressed using the formula for orbital speed, which shows that speed decreases as altitude increases. Additionally, the mass of the Earth affects this gravitational force, but it remains constant for all satellites orbiting the planet.
Why doesn't gravity pull the artificial satellites to Earth?
Gravity pulls the satellites but the orbiting satellites don't fall down towards earth because the speed with which they move balances the gravitational force i.e. Centripetal force = Gravitational force.
Satellite orbiting earth at constant speed is accelerating?
Yes, a satellite orbiting Earth at a constant speed is indeed accelerating. This acceleration is due to the continuous change in direction of the satellite's velocity as it moves along its circular orbit. While the speed remains constant, the change in direction signifies that there is a net force acting on the satellite, specifically the gravitational force exerted by Earth, which keeps it in orbit. This type of acceleration, where the speed is constant but the direction changes, is known as centripetal acceleration.
What is constant about an object in orbit?
An object in orbit is constantly accelerating towards the center of the body it is orbiting due to gravity. The speed of the object remains relatively constant, but its direction of motion is continually changing as it orbits around the central body. The shape and size of the orbit also remain constant if there are no external forces acting on the object.
What is a satellite that stays in one location is called?
No satellites stays exactly still as they could not remain in orbit, but probably you are meaning a geostationary satellite. The orbit of these satellites matches the speed of the earth turning underneath them, so they remain above the same geographical point on the earth.
What is different about the motion of satellites that travel in elliptical paths compared to satellites that travel in circular paths?
Elliptical satellites don't have a constant speed, but circular satellites do
Does a Satellite's speed remain constant?
Yes, it remains fairly constant.

Is the speed of a wave constant?
The speed of a wave can vary depending on the medium through which it is traveling. In a given medium, the speed of a wave is typically constant if the conditions remain constant.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
What happends to the speed of a wave if the medium and temperature and pressure do not change?
The speed of a wave remains constant if the medium, temperature, and pressure do not change. This is because the speed of a wave is determined by the properties of the medium through which it is traveling, and as long as those properties remain constant, the speed will also remain constant.
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
Why doesn't gravity pull the artificial satellites to Earth?
Gravity pulls the satellites but the orbiting satellites don't fall down towards earth because the speed with which they move balances the gravitational force i.e. Centripetal force = Gravitational force.
What will happen if an apple is released from an orbiting spaceship?
An orbiting vehicle has sufficient speed to remain in orbit. If an apple is put outside the vehicle, it will continue in orbit with that vehicle. It will just float there. The apple and everything in the space vehicle will be moving at the same speed, and, because the vehicle is in orbit, everything will have sufficient speed to remain in orbit.

Effect of earth gravity on saterlite?
A continuous acceleration toward the center of the Earth equal to GM/R2 where G is the Gravitational Constant, M the mass of the Earth and R the distance between the satelite and the center of the Earth. If you multiply this by the mass of the sattelite itself, you get the force acting on the satelite to produce the acceleration. It is this force, causing this acceleration, which holds the satelite in orbit. Without it the satelite would obey Newton's first law of motion and just move out in a straight line. Note that this is true of any object orbiting any thing, whether it is an artificial satellite orbiting the earth, a planet or spacecraft orbiting the Sun, or a star orbiting the center of the galaxy.
