Newton s Laws of Motion - Physics 101 / AP Physics 1 Review - Dianna Cowern

Lesson 4 (Newton s Laws of Motion) 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: Problem 1: You push your square space cow, mass 5kg, with a force of 10N. What will be the acceleration of your space cow? Problem 2: Your tiny cow has a mass of 1kg and is standing in a field in Kansas. What force does Earth’s gravity exert on the cow? Problem 3: You are suspending two cows from the ceiling, one below the other. You have really strange hobbies. The lower cow has a mass of 2kg. The upper cow has a mass of 1kg. What is the tension in the rope between the top cow and the ceiling? Problem 4: Now you have two square cows, one mass 4kg, the other mass 2kg, lined up on a frictionless surface. You push on the first cow such that the two cows accelerate at 2 m/s^2. What force does the second cow exert on the first? Special thank you to astrophysicist and folklorist Moiya McTier for her shoutout at the end of the video!
