Lesson 6 (Friction) 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:
Problem1: The coefficient of friction between your car’s tires and concrete is 0.7. Your car’s mass is 1000kg. If you slam on your brakes and the tires lock, what is the magnitude of the sliding friction force acting while you slide? What is your acceleration?

Problem 2: You put your cow on a ramp. Moo. Then you tilt the ramp up, slowly. Just when your cow starts to slide, you measure the ramp angle as 34º. What is the coefficient of static friction between the cow and the ramp?

Thank you to atrophysicist Naomi Rowe-Gurney for her awesome shoutout at the end of the video! You can follow her on Twitter @nrowegurney

In this AP Daily: Live Review session, we will review the main concepts in Unit 2: Dynamics.

We will review Newton’s laws, with an emphasis on free-body diagrams and identifying forces associated with Newton’s third law. We will focus on forces exerted by springs, strings, friction, and gravitational fields, as well as how Newton’s second law can be used to determine the changes to an object’s acceleration when the forces acting on an object change. We will also review practice questions for the AP Physics 1 Exam.

#AP #APDaily #APPhysics1

Modern physics is an effort to understand the underlying processes of the interactions with matter, utilizing the tools of science and engineering. In general, the term is used to refer to any branch of #physics either developed in the early 20th century and onward, or branches greatly influenced by early 20th century physics. Notable branches of #modern_physics include quantum physics, special relativity, and general relativity.


This course contains almost everything you need to know about modern physics.

Lesson 12 (Conservation of Momentum) 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. Compare the momenta of two objects: one with a mass of 260kg moving at 20m/s, and the other with a mass of 1950kg moving at 1m/s.

2. What are two different (common) ways to represent the units of momentum?

3. You and your spherical space cow push off of each other, in space. The cow, which has a mass of 100kg, ends up with a speed of 2.5m/s. Your mass is 50kg. What will your velocity be after the push?

4. What is the total impulse of a rocket that thrusts with a force of 7600kN for 162 seconds?

Special thanks to Cheyenne Polius for her awesome shoutout at the end of the video!
And thank you to the Planetary Society for allowing us to use the footage for their awesome light sail.
