We balanced a meter stick by balancing a torque produced by different
distances and different mass. We adjusted the distance on the moment arm and
added mass on the opposite side to determine how t
1. If the final kinetic energy is greater than the initial kinetic energy in a collision, some of
the internal energy at the time of the collision must have been changed into kinetic
energy. This is called exoergic energy (energy releasing). If KE initial
Knowing acceleration we can find velocity at all times (Vx=V0x+AxT); and position
(x=x0+v0xt+1/2axt^2). Assuming particle moves in 3 dimensions, components of vector a, would
be (ax,ay,az). These components of the vector are independent, meaning the ax on
In projectile motion (absence of air resistance) acceleration is same in magnitude and
direction. Uniform Circular Motion is when something is constant in magnitude of
acceleration or velocity but constantly changes direction ex: Earth, Rotors, etc. Force
When Body A exerts force on Body B, Body B will exert the same amount force back on Body A.
The force applied by Body B will be equal in magnitude and always in the opposite direction of
the force of Body A. As mentioned in class, Newtons third law isnt e
To find center of mass, coordinate system must be employed, and the masses must be
multiplied by their position then divided by the mass of the entire system, derive if trying

The standard of mass is measured by kilograms a SI unit. However, research for a replacement
for the kilogram is underway because atomic masses cannot be measured as accurately with
the standard kilogram. A related unit is known as the mole, it serves to
The passage of Kinematics with Vectors (2.1) starts off by giving the reader a scenario. What
the reader is supposed to draw from this scenario, is that when using vectors your goal is not to
find the sum as an answer, rather the position of a location. F
