Gravity is a force that attracts all objects towards each other. It is what makes everything fall towards the Earth or towards other planets or objects in space. Gravity is like the invisible superglue that holds our massive world together. It is the force by which a planet or other body draws objects towards its center. Without gravity, everything would fly off into space, and there would be no you, no me, no french fries, nada.
Isaac Newton was the first person to seriously study gravity over 300 years ago. He realized that a special kind of force, which we now know as gravity, was acting on all of the objects on Earth, pulling them towards it. Newton also realized that it doesnt matter how heavy an object is either.
Gravity on Earth pulls objects towards the center of the Earth, which is what makes objects fall and gives them weight. Weight is a measurement of the force of gravity between an object and the surface it stands on. If a person stands on a scale, gravity pulls the person against the scale, and the scale shows the strength of this force, or the person’s weight.
Gravity is very important to us. We could not live on Earth without it. The suns gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the suns light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together.
Some interesting facts about gravity include:
- At some point when falling, the friction from the air will equal the force of gravity, and the object will be at a constant speed. This is called the terminal velocity.
- We dont actually "feel" gravity. We only feel the effects of trying to overcome it by jumping or when we fall.
- Gravity always pulls, it never pushes.
Overall, gravity is a fundamental force that affects everything in the universe, and it is essential for life on Earth.
