What is the force that causes objects to accelerate towards the ground?

[surfer-Pax]

i am doing yr 11 physics and have a question compare the velocity of an object as it starts with its velocity when it reaches the bottom of its flight?

it would be equal or a greater fource of (9.8) gravity because you need to have the same amount of force or more to project it up for it to hit the ground
ie' useing a pen instead of letting it go at 2m above the ground and letting gravity do the work, you need to be able to throw it up in the air, in order for it to drop and hit the ground at an equal velocity aka 9.8 or gravity. dose anyone agree?
dose anyone know was this force is called or is it just a baisic one?

The force you are describing is known as a gravitational force, which is the force of attraction between two objects with mass. This force is responsible for an object's acceleration towards the ground due to gravity. The velocity of an object when it starts and when it reaches the bottom of its flight will be equal if the object is in free-fall. That is, if no other forces are acting on the object besides gravity.

Yes, I agree with your explanation. The force of gravity causes objects to accelerate towards the ground at a rate of 9.8 m/s^2. This means that the velocity of an object will increase by 9.8 m/s every second as it falls towards the ground. Therefore, the velocity at the bottom of its flight will be greater than the velocity at the start of its flight. This is because the object has been accelerating the entire time due to the force of gravity.

The force of gravity is a basic force in physics, and it is often referred to as the force of gravity or the gravitational force. It is one of the fundamental forces that govern the motion of objects in the universe. Other examples of fundamental forces include the electromagnetic force, the strong nuclear force, and the weak nuclear force.

I hope this helps answer your question and provides a better understanding of the concept of free fall due to gravity. Keep up the good work in your physics studies!
