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!
