The problem of space debris is solvable if we work together.

This content explains and solves a physics problem involving an inelastic collision in rotational motion. A uniform rod, pivoted at one end, collides with a putty ball that sticks to its end. The solution demonstrates how to calculate...

In this physics science fair project, students will investigate the rebound height limits and linearity of dropped bouncy balls.

Almost everything you could want to know about New Horizon's visit to Arrokoth.

Space junk and debris is starting to be a problem around Low Earth Orbit (LEO) according to the ESA and JAXA. Exactly how much is up there? And are we soon approaching the threshold of Kessler Syndrome?

Contrary to popular belief (as set by movies), cars are not very prone to explosions, and even a car that is on fire is very unlikely to explode. The necessary conditions for an explosion to take place are not met after a car experiences...

Coefficient of restitution: What is it? How is it related to the general bounciness of balls and other objects? Here's a quick, simple and basic explanation of the coefficient of restitution for kids and laymen. Basketballs bounce a lot,...

Bird strike on airplanes is one of the most biggest causes of concern for the airline industry and military. When a bird or a flock of birds hits an airplane, the plane may sustain some serious damage which can have disastrous...

If the Titanic were to collide with the iceberg – a stationary, mammoth object – most of the energy of the impact would have to be absorbed by the ship, which would have only made matters worse. An abrupt stop would have thrown people...

Mercury and Venus have no moons because of their close proximity to the Sun. Any moon orbiting around them is likely be swallowed by the mammoth gravitational pull of the mighty Sun. All planets except for Mercury and Venus have moons....

An iceberg is a humongous rock of ice floating on water, but only a small part of it is visible above the surface of the water. Getting onto an iceberg is more challenging than it seems. Icebergs are massive, so it would be daunting to...
