Answer 1

Answer:

(i) Free fall is caused due to gravity and towards gravity source.

(ii) Acceleration due to gravity means a object in free fall gets accelerated towards gravity source.

(iii) Velocity means accelerating towards a direction.

(iv) Centripetal force means force acting on a certain point.

Answer 2

$answer$

Que-.What is free fall,?

ans.A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. ... Free-falling objects do not encounter air resistance.

Que-.what is accelaration due to gravity?

ans. the acceleration of a body in free fall under the influence of earth's gravity expressed as the rate of increase of velocity per unit of time and assigned the standard value of 980.665 centimeters per second per second. — called also g

Que-.what is escape velocity?

ans. In physics, escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to achieve an infinite distance from it. Escape velocity is a function of the mass of the body and distance to the center of mass of the body.

Que.what is centripetal force?

ans. Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation,"
