What is the nature of motion of an object falling freely under the action of gravity?
The motion of a body will be being drawn towards the center of the earth where it is sugested gravity is centered. Our moon is being drawn towards the center of the earth, but because of its speed around the earth it always continues to fall towards it but never actually reaches it.
In general, the body will accelerate toward the source of the gravity (another object or group of objects) with acceleration = G x Ms / r2, where G = gravitational constant, Ms = mass of the gravitational source (other object) , and r = distance between the centers of mass of the two bodies. This motion will be added to any existing motion the body has already.

Which type of motion is exhibited by a freely falling body?
A freely falling body exhibits uniform acceleration motion due to the force of gravity acting on it. This means that the body's speed increases by the same amount every second as it falls towards the Earth.
How equation of motion are modified for freely falling objects?
For freely falling objects, the equation of motion is modified to account only for the effects of gravity. The equation becomes: y = 0.5gt^2, where y is the height of the object at time "t" in seconds, and "g" is the acceleration due to gravity (approximately 9.8 m/s^2). Friction and other forces are typically ignored in these scenarios.
What are the units for gravity and how are they measured?
The units for gravity are meters per second squared (m/s2). Gravity is typically measured using instruments like accelerometers or by analyzing the motion of objects falling freely under the influence of gravity.
Does an object that is freely falling have mass?
Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
What changes in a freely falling body?
In a freely falling body, its velocity increases due to the acceleration caused by gravity. The acceleration is constant (9.8 m/s^2 on Earth), and the body's motion is only affected by gravity, not air resistance. The body's position changes continuously as it falls towards the ground.

A freely falling body exhibits uniform acceleration motion due to the force of gravity acting on it. This means that the body's speed increases by the same amount every second as it falls towards the Earth.
In what way is the motion of a freely falling object different from the motion of the cart?
The motion of a freely falling object is solely under the influence of gravity, leading to a constant acceleration downwards. In contrast, the motion of a cart can be influenced by various factors such as friction, external forces, and its initial velocity, resulting in a more complex trajectory.

When a body falls freelyto the ground its motion has uniform motion?
No. "Uniform motion" means motion at a constant speed in a straight line. But the speed of a body falling freely to the ground is continuously increasing, in response to the force of gravity.

The units for gravity are meters per second squared (m/s2). Gravity is typically measured using instruments like accelerometers or by analyzing the motion of objects falling freely under the influence of gravity.

Yes, an object freely falling still has mass. Mass is a measure of the amount of matter in an object, and it remains constant regardless of the object's motion. The force of gravity acting on the object is what causes it to fall.
What happens to the weight of the body when it falling freely under the action of gravity?
Nothing. If the 'weight' of a body is the gravitational force between the body and the Earth, then as long as the body stays at about the same distance from the center of the Earth, its weight is constant, and has no connection with its motion.
What changes in a freely falling body?
In a freely falling body, its velocity increases due to the acceleration caused by gravity. The acceleration is constant (9.8 m/s^2 on Earth), and the body's motion is only affected by gravity, not air resistance. The body's position changes continuously as it falls towards the ground.
What is constant for freely falling body?
The acceleration due to gravity is constant for a freely falling body. This means that the object will experience a constant acceleration of 9.81 m/s^2 (on Earth) in the downward direction, regardless of its mass. This allows us to predict the motion of the object using equations of motion.
What Is the motion of a falling object when the only force acting on it is gravity.?
downward motion
How could the uniformly accelerated motion be modified to study the acceleration of a freely-falling body?
At short distances - up to a few kilometers - gravity can be considered constant, and therefore, a body in free fall (i.e., neglecting other forces, such as air resistance) will be uniformly accelerated. Over longer distances, the force of gravity is no longer the same; this will have to be considered for the "modification" (for example, less force = less acceleration). Close to the Earth's surface, in practice, air resistance has to be considered (but this is no longer "free fall").
What is it called when the motion of a body when only gravity is acting on the body?
You're probably thinking of the term 'free-fall' or 'freely falling', or in relativity you might say it follows a 'geodesic'.
