... Begin Ch 4: Dynamics (the “why” of motion) F = 0 leads to a = 0. Discuss “balanced forces” and “net.” History: pre-1600: p. 83, section 4.2. 1st Law: inertia. 2nd Law: F (net) = ma (and w = mg) m Unit for force: the Newton (N) or kg 2 s Step 1 for problem solving: draw free body diagram (FBD) Sta ...

... for a falling mass hanger. We need a system of one object – the mass hanger. Hmm. You can’t have a mass hanger without a string to attach it to. And all position measurements are associated with the cart, not the hanger. So we need a cart, but then again we don’t. We need a cart that won’t interfere ...

Impulse and Momentum Review
... We’ve seen that if you want to change the momentum of an object or a system of objects, Newton’s second law says that you have to apply an unbalanced force. This implies that if there are no unbalanced forces acting on a system, the total momentum of the system must remain constant. This is another ...

... is called the force of static friction. • Static Friction = Fs • As long as the object doesn’t move, the static friction is always equal to the opposite in direction to the applied force. • Fs = -Fapplied • When the applied force is as great as it can be without moving the object, the force of stati ...

... A disk, for which the moment of iner3a is I1, rotates about a ver3cal, fric3onless axle with angular velocity ω0. A second disk, which has moment of iner3a I2 and is not rota3ng, drops onto the first disk, as illustrated below. The disks s3ck together, which results in their both spinning with a ...
