Gravity does act on a satellite so why is normal force 0 for an object placed inside it?
The normal force in a satellite is zero because a satellite is in a state of free fall, meaning that it is constantly accelerating towards the Earth due to the force of gravity. In this state, the only force acting on the satellite is gravity, and the normal force is not needed to counteract any other forces.
A satellite stays in orbit due to a balance between its forward motion and the pull of gravity. As the satellite moves forward, it is constantly falling towards the Earth due to gravity, but its forward motion keeps it from crashing down. This is known as a stable orbit.
Yes, there is still a force acting on a satellite even if the normal force is zero. As mentioned before, the only force acting on a satellite is gravity, which is what keeps it in orbit.
No, the normal force in a satellite will always be zero as long as it is in a state of free fall. This is because the normal force is a contact force that only occurs when an object is in contact with a surface, and in the case of a satellite, there is no surface or object for the satellite to come into contact with.
No, the normal force does not play a role in the motion of a satellite. Instead, it is the force of gravity that determines the path and speed of the satellite in orbit.
