How Much is a Mermaid Attracted to a Doughnut? A practical, everyday example of Newton’s Universal Law of Gravitation.

Derivation for the impulse and momentum formula for a system of particles. Notice that if the sum of external forces = 0 then momentum in the system is conserved!

According to NASA, the mass of the Earth is 5.97 x 10^24 kg, the mass of the Moon is 7.3 x 10^22 kg, and the mean distance between the Earth and the Moon is 3.84 x 10^8 m. What is the force of gravitational attraction between the Earth...

Given certain parameters, how would you solve this problem in X direction?<br/>

Scalers and Vectors, Part 4

Proof that the Force Normal and the Force of Gravity are not a Newton’s Third Law Force Pair.

The equation for #AngularMomentum of #RigidObjects with shape is introduced and a simple example of angular momentum is solved for.

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...

In this video, students learn how to determine the units for their answers when using formulas. The teacher explains the importance of including units in calculations and highlights common mistakes. Through examples involving volume,...

Calculus based review of Newton’s three laws, basic forces in dynamics such as the force of gravity, force normal, force of tension, force applied, force of friction, free body diagrams, translational equilibrium, the drag or resistive...

In this wonderful introduction to the nature of matter, students will explore how they depend on and interact with matter. The program clearly demonstrates some of the physical and chemical properties of matter. Special attention is paid...

Calculate the altitude of a satellite in geostationary orbit which is an orbit with the same 24 hour period as the Earth and always located directly over the same location on the equator. Geostationary orbit is a special case of...

Given certain parameters, how would you solve this problem?<br/>
Physics Work, Part 2

Many vibrating systems oscillate according to the wave equation. A string fixed at both ends is just one example. In general, a vibrating string will consist of an infinite number of natural frequencies and an infinite number of...

Given certain parameters, how would you solve the second and third part of this problem?<br/>
Physics Power, Part 3

This video explores the behavior of objects when they fall under gravity. It starts with a quick recap of Newton's Second Law, which explains the relationship between force, mass, and acceleration. The video then looks at how weight is...

We think space and time are the structure of the universe. Yet Einstein argued 'space and time are modes by which we think and not conditions in which we live'. And philosophers, Kant and Heidegger, saw space and time as the framework of...

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...

Lesson 9 (Work and Energy) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this video: 1....

I demonstrate that the magnitude of the force normal and force of gravity acting on an object are not always the same, even though many students want to assume this is true. This is an example of where showing your work is incredibly...

It explains mass and weight. It also talks about the weight of an object on moon.
