Forces acting at an angle: Resolving Forces
... 1. A computer base unit of mass 4.5 kg is dragged along a smooth desk. If the tension in each arm of the person dragging it is 16 N and acts at 22◦ above the horizontal, then what is the normal reaction force? 2. A computer base unit of mass 7.5 kg is dragged along a smooth desk. If the normal conta ...

Using the Lagrangian to obtain Equations of Motion
... For comparison, it will be instructive to read Section 1.7 in which Zak presents an example of a cart with inverted pendulum. Instead of using the Lagrangian equations of motion, he applies Newton’s law in its usual form. There are a couple of differences between the examples. Specifically, in the e ...

Special Rotational Dynamics Outline
... momentum is conserved (constant). This is why, for example, an ice skater spins faster when he/she pulls in arms to decrease moment of inertia, I. The angular momentum, Iω is constant, so if I goes down, angular velocity (ω) must go up. Likewise, if the net torque on a system of objects is zero, the ...

Force and Acceleration
... For example, when we are traveling in a bus, and bus is going at fast speed. The driver suddenly applies the brake and we are unable to control ourselves and our body plunges forward. It is because the bus and our body are moving at constant velocity. That is why in cars etc. we use seat belts. So t ...

... An old “45” vinyl record is meant to spin at 45 rpm. Its diameter is 7 inches (17.78 cm). Suppose that you glue a pea to the edge of the record and spin the record at this frequency. Find the pea’s (a) angular speed , (b) tangential speed, and (c) centripetal acceleration . Now suppose that you glue ...

Harmonic notes
... We have been dealing with straight line motion or motion that is circular. There are other types of motion that must be dealt with. Specifically a motion that repeats itself over and over. Such a thing has its very own physics name. “The name?” the desperately curious, interested advanced physics st ...
