This is a complicated free-fall problem where you have to identify that the velocity at the top of the path is zero in the y-direciton. Furthermore, you have to look at it from the perspective of the whole event and splitting the problem into two different parts. A classic free-fall acceleration example problem.

In this short video, students will learn about the vocabulary word "solemn". Solemn is defined as earnest: having or showing sincerity or gravity, humorless: having or showing no joy or humor, and religious: observed with sacred or religious ceremony. Good examples are given. This is a good resource to introduce this word into the upper elementary classroom. (01:01)

This video uses balancing on a unicycle as an example to explain net force (mass x acceleration). It explains how all of the outside forces, such as gravity, contact force, and friction help to create balance when riding a unicycle. It also explains counter-steering to move the point of contact and control the direction of the unicycle. (4:32)

Modern science has done amazing things: creating covid vaccines, sending humans to the moon, finding the ultimate nature of gravity. What makes it so powerful—and so different from the attempts to understand nature made by the philosophers and monks of old?
Leaping from Aristotle to Descartes to quarks and gravitational waves, Michael Strevens will show that much of science’s power derives from an epistemic limitation that can only be understood as irrational. The paradigmatic scientist is a paradigmatic reasoner in many ways, but in at least one way, their perfection as a scientist lies in the deliberate cultivation of a gaping intellectual blind spot.

For the past 23 years Andrea Ghez, professor of physics and astronomy at UCLA, has been collecting data on stars that orbit black holes. She found that their motion provided an opportunity to test the fundamental laws of physics. “We asked how gravity behaves near a super-massive black hole and whether Einstein’s theory is telling us the full story.

Saturn is the crown jewel of the solar system, beautiful and fascinating. It is a gas giant, and has a broad set of rings made of ice particles. Moons create gaps in the rings via their gravity. Saturn has dozens of moons, including Titan, which is as big as Mercury and has a thick atmosphere and lakes of methane; and Enceladus which has an under-surface ocean and eruptions of water geysers. While we are still uncertain, it is entirely possible that either or both moons may support life. (12:15)

Resource produced by WGBH and funded by the National Science Foundation. (01:37)"The Moon, Earth's natural satellite, seems to hover in the sky, unaffected by gravity. However, the reason the Moon stays in orbit is precisely because of gravity -- a universal force that attracts objects. With the right combination of speed and gravity, satellites can fall around, instead of into, the body that they orbit. In this animated video segment adapted from NASA, learn about how the Moon stays in orbit around Earth." (01:37)

Mars can be terraformed into an Earth-like paradise. By reestablishing a magnetic field to protect Mars, thickening the atmosphere, removing perchlorates from the soil, creating an ozone layer, and adjusting the atmosphere, we can terraform the red planet into a habitable paradise. A terraformed Mars would still be very different from Earth. The days and years would be longer, the gravity would be lower, and the climate would be much different. While terraforming Mars is possible, it would likely take hundreds or even thousands of years and would require technology and mega-projects beyond humanity’s current capabilities. (08:11)

Sir Isaac Newton (25 December 1642 – 20 March 1726/27) was an English physicist, mathematician and astronomer. He is well known for his work on the laws of motion, optics, gravity, and calculus. In 1687, Newton published a book called the Philosophiæ Naturalis Principia Mathematica in which he presents his theory of universal gravitation and three laws of motion. (04:17)
