An object falling under the influence of gravity and no other force is said to be in free fall.?
true
Motion that is under the influence of gravity alone is called?
Free fall is the term in Newtonian physics used to describe the motion of an object under the influence of gravity alone. Such an object moves along a geodesic. One example of an object always in free fall is Earth's moon.
What is the differnece between mass and gravity?
This is like asking: What is the difference between electricity and weight? Mass is the amount of physical material in an object, and gravity is a force. You may be asking about the fact that the mass of an object (under ordinary non-relativistic conditions) remains the same even if the object is floating freely in space. On the other hand, the weight of an object is a measure of the amount of gravitational force exerted on an object. On the surface of the earth, an object may weigh many tons, and have an associated mass measured in grams. That same object is weightless in space but has the same number of grams of mass no matter where it is. This is why you might see answers indicating that the earth or some other planet is weightless. This seems absurd, but it is true. The planets are very massive, but unless you can put them on a scale in a gravitational field, they don't weigh a thing.
When an object changes speed does its acceleration change?
Not necessarily. Example: an object falling only under the influence of gravity accelerates at a constant rate of about 9.8 meters per square second. Its speed, however, changes.
Does gravity determine the speed and direction of a moving object?
No. The ball in a roulette wheel, a baseball, and a golf-ball are all moving andall under the influence of gravity, but all executing very different patterns ofspeed and direction.
What would you call an object that moves through the air under the influence of gravity?
That would be a projectile.

What is the definition of free-falling parchute?
"Free fall" means that an object falls only under the influence of gravity; specifically, air resistance can be ignored. An open parachute does not normally fall in this category."Free fall" means that an object falls only under the influence of gravity; specifically, air resistance can be ignored.

Is it possible for an object's weight to be different than its mass?
More then possible! It is so by definition. Mass is the "amount" of material in an object; weight is the force the object exerts under the influence of gravity.
What are the examples of gravity?
-- Vast hydrogen clouds shrink and compress under the influence of gravity to form stars. -- Tiny particles of dust, gas, and rock aggregate under the influence of gravity to form planets. -- Planets execute motion in closed orbits around stars under the influence of gravity. -- Strapless evening gowns stay up in consideration of the gravity of the situation that would ensue if they did not.

If an orbit of a planet breaks?
The orbit of a planet is not any kind of physical object; it cannot "break". An orbit is the path that a satellite (natural or artificial) takes under the influence of gravity.
What are the conditions for a freely falling object?
Weight should be the only force for a free fall of an object. They should fall under the influence of gravity only. They should not face any significant force of air resistance.
What is falling body?
is an object that moves under gravity only.
