What forces act on a falling object?
The main forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward toward the ground, while air resistance, or drag, slows down its descent by pushing upward against it. The net force of gravity minus air resistance determines the object's overall acceleration as it falls.
Does changing the mass of a free falling body affect the value of the acceleration of gravity?
No, changing the mass of a free-falling body does not affect the value of the acceleration due to gravity. The acceleration due to gravity is a constant value that is independent of the mass of the object. All objects fall at the same rate in a vacuum due to gravity.
What is the speed of a falling body?
The speed of a falling body increases by 9.8 m/s^2 due to gravity, assuming no air resistance. This acceleration is constant until it reaches terminal velocity when air resistance matches gravitational force, causing the speed to stabilize.
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.
Does a rock falling from a cliff have a constant acceleration?
Yes. Every body that is falling, (if there is no other force then the gravity force) will fall in constant acceleration. Mass does not affect the acceleration of the body. According to Newton's second law: F=m*a m*g=m*a g=a F= Force m= mass a= acceleration g= gravity acceleration m*g= the force of gravity

What is falling body?
is an object that moves under gravity only.
How does the weight of a falling body compare with the air resistance it encounters after it reaches terminal velocity?
If its speed of fall is no longer changing, then its acceleration is zero. That tells you that the forces on it must be balanced, so the upward force of air resistance must be exactly equal to the downward force of gravity.
Is the vertical motion of a falling object dependent on the mass of the object?
Gravity's action on a falling body is dependent on the masses of both bodies and the difference between their centers. Typically the falling body's mass is negligible, being on orders of magnitude smaller than the larger body, and will not affect the acceleration to any measurable degree. So, typically the answer would be: No.
What is absolute velocity is it the other name for the velocity of a free falling body when the net force of air resistance and gravity is zero?
Absolute velocity refers to the speed and direction of an object relative to a fixed point, regardless of any external factors. In the context of a free falling body with zero net force due to air resistance and gravity, its absolute velocity would be constant and equal to the velocity just before air resistance became negligible.
How do air resistance and gravity affect a falling object?
Well, isn't that just a happy little question! Air resistance acts like a gentle breeze, slowing down the object as it falls. Gravity, on the other hand, pulls the object down towards the Earth. Together, they create a beautiful dance that determines how fast an object falls and how it moves through the air. Just remember, there are no mistakes in science, only happy little accidents!
A free body diagram of a ball falling in the presence of air resistance would show A only a downward arrow to represent air resistance B a downward arrow to represent gravity C neither?
Neither. It would need a downward pointing arrow for the force of the acceleration due to gravity and a second arrow for the air resistance pointing up.
