All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Gravity not only maintains the stability of these orbits but also influences phenomena like tides on Earth, caused by the moon's gravitational pull. The paper, authored by David Jewitt from the ...

When we think about orbits, we usually picture the Earth zooming around the sun. But does the sun just sit there? Or is it on its own journey? I asked my friend Guy Worthey. He’s a space scientist at ...

Orbital resonances can change how gravity influences two bodies, causing them to speed up, slow down, stabilize on their orbital path and sometimes have their orbits disrupted. Think of pushing a ...

In Isaac Newton’s theory of gravity, the gravitational attraction between two objects is proportional to the product of their masses divided by the distance between them squared, and this attraction ...

From planetary orbits to pendulum swings, MATLAB makes it possible to simulate gravity and motion with precision. Using built-in physics toolboxes, you can explore everything from Newton’s laws to ...
