👉 Learn how to find the missing measure of a segment. A segment is a line that has two endpoints. A segment can be subdivided into several portions. The length of the segment is the sum of all the sub-divisions of the segment. Thus, when...

In this video, Professor Orbak and his lab assistant, Sweet Pepper Club, demonstrate how to break the Guinness World Record for the most marshmallows caught in the mouth with a homemade catapult in one minute. They provide step-by-step...

The video is a lecture that explains the two features of a wave, namely wavelength and amplitude. It starts with a demonstration of a transverse wave and illustrates how the wave propagates while oscillating. The peaks and troughs of the...

Metric system.

What is proportionality? How does it relate to pattern? Learn the answers to these questions and explore the basics of proportional relationships in this video.

A new study shows the size of giant squids may be bigger than imagination, that they could reach the size of 20 meters in total length.



The study analysed the data of beak size and the mantle length to standard and total...

The video is a lecture on acceleration and how we quantify the rate of change of an object's velocity. The presenter discusses the concept of acceleration, how it is measured, and the equation used to calculate it. Examples are provided...

👉 Learn how to find the volume and the surface area of a sphere. A sphere is a perfectly round 3-dimensional object. It is an object with the shape of a round ball. The distance from the center of a sphere to any point on its surface is...

This video explains the concept of work and energy transfer when a force is used to displace an object. The video demonstrates how to calculate work done and the energy transferred in different situations. The video provides examples...

Metric system.

NASA scientists have discovered that grooves found on Phobos, the larger of Mars' two moons, are signs that it is slowly breaking apart, according to an article published by NASA on Tuesday. Scientists previously believed that the...

It explains velocity-time graphs for uniform velocity, uniform acceleration and non-uniform accelerated motion.

What are the formulas of predictor equations? What do each equation mean?<br/>
Equations Of Motion In One Dimension, Part 1

We’ve all heard the saying, “what goes up must come back down.” But when we launch rockets and satellites into space, they (usually) don’t come back! Let’s prove this saying wrong, using Physics! This lesson will introduce and derive...

Development of Quantum Mechanics: Photoelectric Effect Example 1

This video is a lecture on velocity time graphs, which explains how the velocity of an object can be graphically represented with respect to time. The video describes how velocity time graphs are constructed, and how positive and...

In this video, two free runners attempt to break world records in urban acrobatics known as free running. They showcase impressive jumps and flips between two objects, with one of them successfully setting a new world record. Discuss...

Electric Field of Uniformly-Charged Rod

Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth and the object. The gravitational...

The video is a lecture presentation that explains the difference between scalar and vector quantities in physics. The presentation also covers how vector quantities can be combined, with examples of forces acting in the same direction,...

This is an introductory lesson about Uniformly Accelerated Motion or UAM. I show examples of 5 different objects experiencing UAM, some are even in slow motion. We also learn my simple way of remembering how to use the UAM equations.

Doodle Science teaches you high school physics in a less boring way in almost no time!

The range of human hearing is 20Hz to 20,000Hz. Ultrasound waves are just sound waves with a frequency above 20,000Hz. When ultrasound reaches a boundary between two media with different densities, some are partially reflected back and...
