You can any of several formulae for constant acceleration, found in any physics textbook. Acceleration due to gravity, near the Earth's surface, is about 9.8 meters/second2.
Oribtal points are any location in space where an object may freely orbit around a planet, or other astral object, without falling to the planet below.
motion of free falling object does not have friction, while motion of the cart has force of friction
only if it equaled acceleration due to gravity (about 9.8 (m/s)/s)
Flexiblity
Flexibility is being able to move your arms and legs without pain or tightness.
If the body is freely falling, this sum will remain constant.
Yes, mass is an intrinsic property of matter. However a freely falling object will experience no weight.
Velocity
The equation of motion is not modified. Net force = mass x acceleration, whether freely falling or not.
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
Freely falling bodies
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
force and gravity
no force act on it
No characteristics of a falling body appear on the list provided with the question.
