Answer 1

Answer:

Your Answer:-

Explanation:

Artificial Satellites

An artificial satellite orbiting around the earth does not fall down. This is so because the attraction of earth provides the necessary acceleration for its motion. This acceleration is “constant” in magnitude but “changing in direction”.

Answer 2

In artificial satellites the necessary acceleration is provided by the only force that acts on the satellite-the gravitational force.

Explanation:

• The gravitational force, which is the sole force acting on the satellite, provides the acceleration.
• In other words, a satellite in a low circular orbit around the Earth will travel at around 8 km/s and will take about an hour and a half to complete one orbit.
• Because they and the satellite are descending at the same pace, objects within an orbiting satellite appear to be weightless (approximately 9.80 m/s²).
