An astronaut's weight in an artificial satellite revolving around the Earth is:

The direction of centripetal acceleration is always ____ the circular path.

The satellite's orbital velocity does not depend upon:

If the speed of the orbiting body is less than the orbital velocity it:

If r represents the radius of the orbit of a planet of mass m moving around the Sun of mass M, the orbital velocity of the planet is given by:

If suddenly the gravitational force between the Earth and a satellite revolving around it becomes zero, what will happen?

The force acting between the objects in space is __________ force.

What would happen to the Earth if the gravity of the Sun was lost someday?

What would happen to the Moon if the gravity of the Earth was lost someday?

Which one of the following options is correct about the centripetal force?
a. It pulls an object towards the other
b. It keeps the body moving in a circular path
c. It acts perpendicular to the motion of the body
d. It is an attractive force

Which one of the following options is correct about the motion of the Moon around the Earth?
a. The Moon falls towards the center of the Earth at every point at every point of its motion.
b. The Moon hits the surface of the Earth.
c. The direction of motion of the Moon and the direction of gravitational force are always perpendicular.

In which direction does the velocity of a body move in a circular motion point?

In space, there is:

The direction in which the gravity of the Earth acts is:

The force of gravity acts along the line joining centers of the two bodies. Regarding the direction, it always acts towards the center of the heavier body.

What is the direction of the centripetal acceleration w.r.t the centripetal force?

Which force is necessary to keep a body moving a circular path?
