That is called gravity.
When a force is applied to an object, it accelerates. for example, if you push an object, the object accelerates away from you and, eventually, will move away from you..
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
changes the motion of the object
When an object accelerates, the force is unbalanced.
I can say that a force is the ONLY thing that can accelerate an object.
Accelerates the motion of an object.
they will accelerate at the same time. Just like what happens when a heavy and light object are dropped from the same height in a vacuum, they will reach the ground at the same time.
The Weight of an object is not a function of Height. When an object is dropped from a height, it accelerates up to a fixed velocity. It strikes the ground that results in a Force of the imact. The force required to Stop an Object is proportional to its Mass and the acceleration(or deceleration which is the change in velocity over time). Force = 1/2 Mass X Acceleration The Acceleration(or deceleration) is an instantenous stop so it would be approximated by 1/2 the speed it had before it hit the ground. Use that equation with the correct units and you can calculate the Force. I hope this is the answer to your Q.
When an unbalanced force acts on an object, the weight of the object decreases.
Gravity is a force that accelerates the falling object towards the ground.
The object accelerates.
It accelerates.
