Gravity is a pull.
Understanding Gravity as a Pulling Force
In Newtonian physics, gravity is understood as an attractive force between objects with mass. This means that each object pulls on every other object. The more massive an object is, the stronger its gravitational pull. When you're close to the Earth, its enormous mass exerts a strong downward pull on you, which we experience as weight.
Example:
Imagine an apple hanging from a tree. The Earth's gravity pulls the apple downwards. If the stem breaks, the apple falls towards the Earth because of this gravitational pull. It isn't being pushed down by anything; it's being pulled.
Why It's Not a Push:
The concept of gravity as a push is less accurate and doesn't align with the standard model of gravity described by Einstein's General Relativity, which explains gravity as a curvature of spacetime caused by mass and energy. Objects move along these curves, which we perceive as a gravitational pull. While the effects can sometimes be interpreted in other ways in extremely specific circumstances, the fundamental force is best and most accurately described as a pull.
