Freely falling objects
All objects accelerate at approximately the same rate. Freely falling objects are therefore objects, ... It must fall for somewhere between 13s and 14 s. ...
2.
Projectile Motion
We can view the motion of the projectile as a superposition of two motions, a motion with constant velocity v0 in the initial direction and a downward ...

Uniform Circular Motion
Uniform Circular Motion. An object moving in a circle of radius r with constant speed v is accelerating. The direction of its velocity vector is changing ...

Forces and Fields
They have no net charge. The charge of the nucleus is exactly canceled by the charge of the electrons. We have exact cancellation, because charge is ...

Simple Harmonic motion
Assume the spring is stretched a distance A and then released. ... Neglecting friction, it comes to a stop when the spring is compressed by a distance A and then accelerates back ... (c) Find the maximum acceleration of the particle. ...
