Newton’s first law says that a body will remain in a state of rest, or move in a straight line at a constant speed, unless it is
dangina [55]

Answer:

Gravity

Explanation:

The Hubble is continually attracted to the earth due to the action of gravity. Therefore, it is thanks to gravity that the space telescope is kept in orbit. Without him, the direct motion generated by inertia would take him out of course. Gravity slows it down and keeps it in the curved path of its orbit around the Earth.

Alyse runs to her classroom which is 20 meters away. She forgets her physics book in her locker and must return 20 meters in the
notka56 [123]

The average velocity of Alyse is 0 m/s.

<h3>What is the average velocity of an object or a person?</h3>

The average velocity of a person is the average of all the velocities of moving as it moves.

Velocity on its own is the ratio of the displacement of a body and the time taken for that displacement.

Mathematically:

  • Average velocity = total displacement / time taken

Displacement is a vector quantity that measures the distance traveled by a moving body in a specific direction.

Hence, average velocity and velocity are both vector quantities.

Displacement takes a measure of the shortest possible distance along a straight line from the beginning of the motion until the end of the motion.

Calculating the average velocity of Alyse:

Assuming the initial direction is positive and n=backeard direction is negative:

Total displacement = 20 m + - (20 m)

Total displacement = 0 m

total time = 3 minutes

Average velocity = 0 m/ 3

Average velocity = 0 m/s
