Which best explains why a satellite accelerates?
A) It is always changing direction.
B) It is constantly slowed by gravity.
C) It does not have forces acting on it.
D) It is weightless when it is in orbit.

Respuesta :

A) it is always changing direction

The correct option is, (A) It is always changing direction.

What is the force that causes a satellite to accelerate?

  • A high-speed satellite is affected by gravity, which causes it to stray from an inertial course and change its trajectory.
  • In fact, a satellite is speeding up toward the Earth because of gravity.

What is the direction of acceleration of a satellite?

  • The ellipse's focus is where the satellite is being accelerated.
  • Additionally, in accordance with Newton's second rule of motion, the acceleration of the ellipse's focus is parallel to the direction in which the net force acting on the satellite is directed.

Why does gravitational force change the speed of a satellite?

  • Because there is a component of the gravitational force in the direction of the satellite's motion, the gravitational force affects the speed of a satellite in elliptical orbit.
