PHYSICS 11-10-17 Forces with Pulleys and Friction

PHYSICS: Here’s a different take on forces – an application of horizontal forces, vertical forces, friction, all at once! Wow! Great job on solving the problem – can you now go see if you can solve it by yourself?

Thanks, Matthew, for the visual of almost weightlessness! πŸ™‚

PHYSICS: Great first day of chapter 4! So did you really think I was going to send those eggs flying across the room? And remind me again why they didn’t? I love Newton’s first law – the law of inertia. Let’s play with a little tomorrow. Can you use what you know about mass and inertia to find the mass of an unknown object? I know you can! πŸ™‚
