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....

Conservation of Momentum Summary

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...

We just learned about plate tectonics, so let's see how that fits into a global-scale model for the formation and destruction of supercontinents called the Wilson Cycle. How do supercontinents like Pangea form and split up? It's an...

Quantum computers are still years away, but a trio of theoretical physicists has already figured out at least one talent they may have. The theorists, including one from the National Institute of Standards and Technology (NIST), have...

This video explains the concept of momentum and how it is dependent on mass and velocity. It also covers the conservation of momentum and the different types of collisions. The video includes a simulation experiment with automobile...

A 73 kg mr.p steps off a 73.2 cm high wall. If mr.p bends his knees such that he stops his downward motion and the time during the collision is 0.28 seconds, what is the force of impact caused by the ground on mr.p?

Demonstrating and measuring how a helmet changes impulse, impact force and change in time during a collision.

Why heavy objects theoretically falls a bit faster. By using newton i'm looking at what happens when a 1 kg object is dropped. then what happens with bigger objects. It turns out, that the earth is not stationary, and will accelereate...

Harvard scientists says origin of first ever interstellar object detected in our solar system remains unknown.

In this video we will begin to look at some of the

key features...

This video is a lecture presentation on the principle of conservation of momentum. It explains the concept of conservation of momentum and applies it to various situations, including collisions and cutting a piece of string between two...

The most exciting SciFi movies have tons of space explosions. But how effective would explosions be in outer space with no atmosphere to carry the blast wave? Could a hypothetical explosion hurt you in space?

The Physics Girl team visited LIGO once again. This place is Dianna's obsession.

Excerpts from National Science Foundation Director France Córdova's remarks at the press conference announcing the first gravitational wave detection of a neutron star collision and the first time a cosmic event was seen both in...

Wearing a helmet is all about impulse, change in momentum and the force of impact. This video illustrates why you should secure your helmet to your head. Thank you very much to Colton and Jean Johnson who said yes when I asked them if...

This video is a lecture presentation on the topic of conservation of momentum in physics. It explains the principle of conservation of momentum and how it can be used in calculations. The video provides examples of collisions between...

This video discusses collision theory and how it applies to chemical reactions. The concept of activation energy and how it relates to the rate of a chemical reaction is explained. The video goes on to explore three ways that the rate of...

A 28.8 g yellow air hockey disc elastically strikes a 26.9 g stationary red air hockey disc. If the velocity of the yellow disc before the collision is 33.6 cm/s in the x direction and after the collision it is 10.7 cm/s at an angle...

Scientists have discovered the remnants of what they call a “fossil” galaxy buried in the inner depths of the Milky Way.

The video explains collision theory and activation energy in chemistry. It demonstrates the concept of how reacting particles need to collide with sufficient energy to break reactant bonds and form new products. The video also explains...

Scientists and engineers installed a new component in the core of the ATLAS detector--one of two general-purpose detectors at the Large Hadron Collider. This new component, called the Insertable B-Layer, sits merely centimeters from...

Review of the Rotational Dynamics topics covered in the AP Physics 1 curriculum.

This video is a lecture presentation on the topic of momentum and safety. The presenter discusses the relationship between force and rate of change of momentum and provides examples of how changing the force acting on an object during a...
