In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.

In his lab at Penn, Vijay Kumar and his team build flying quadrotors, small, agile robots that swarm, sense each other, and form ad hoc teams -- for construction, surveying disasters and far more.

In this video Paul Andersen explains that the angular momentum of a system will be conserved as long as there is no net external torque. Both point objects and extended objects are covered along with several examples.

Denial of Service (DOS) or Distributed Denial of Service (DDOS) attacks take down servers by distracting them with meaningless traffic until basically they can't take it any more. The way we talk about the result of a software program...

An incredibly bright burst of energy and a dent covered with ice give us insights into planetary and universal structure.

In this video Paul Andersen explains how inertial mass and gravitational mass are equivalent. He shows you too simple methods for calculated individual inertial mass and gravitational mass. Albert Einstein used this principle to build...

You're on an airplane when you feel a sudden jolt. Outside your window nothing seems to be happening, yet the plane continues to rattle you and your fellow passengers as it passes through turbulent air in the atmosphere. What exactly is...

Despite the rise of renewable energy, the backbone of the power grid is fossil fuels. Adapting the grid to green energy sources is more complicated than flipping a switch.

What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and...

Hank talks about space elevators, and why we shouldn't expect to see one any time soon.

In this edition of IDTIMWYTIM, Hank addresses the so-called centrifugal force, and explains why you really mean centripetal force.

Adam Savage walks through two spectacular examples of profound scientific discoveries that came from simple, creative methods anyone could have followed -- Eratosthenes' calculation of the Earth's circumference around 200 BC and...

Forces are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates then a force is present.

Adam Savage walks through two spectacular examples of profound scientific discoveries that came from simple, creative methods anyone could have followed -- Eratosthenes' calculation of the Earth's circumference around 200 BC and...

Why would it be hard to pedal a 10,000 pound bicycle? This simple explanation shows how Newton's 3 laws of motion might help you ride your bike.

I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of...

Learn about inertia and its role in resisting changes in motion. Discover how mass relates to inertia and why it's crucial in understanding an object's behavior.

This video discusses Newton's first law of motion, also known as the law of inertia. It explains how Newton built upon the experiments of Galileo to formulate this law. The video illustrates the concept using the example of a ball on the...

DIY SCI host Steve Spangler demonstrates one way to solve the friction problem with the law of inertia.

This video explains how the removal of mass affects an object's rotational inertia, demonstrating the calculation of percentage decrease in rotational inertia when an innermost or outermost particle is removed.

This content analyzes the motion of a hollow sphere rolling without slipping up an incline. It demonstrates how to determine the initial rotational and translational kinetic energies from the total, calculate the initial speed of the...

This content introduces the Law of Conservation of Angular Momentum, stating that if the net external torque on a system is zero, its angular momentum (L) remains constant. It draws a parallel with the conservation of linear momentum and...

Finally understand Newton's Laws with clear, step-by-step explanations and simple calculations! This comprehensive guide breaks down all three laws of motion in a way that actually makes sense. You'll learn how to solve force and...

Sound devices in poetry enhance rhythm, mood, and meaning by emphasizing certain words and phrases. Amanda Gorman’s The Hill We Climb exemplifies five key sound devices: alliteration, assonance, consonance, rhyme, and repetition. These...
