Physics Simulation
Displacement, Velocity, and Acceleration
In the session long projects for this class, you will be asked to conduct experiments in a "virtual" laboratory.
We will use the falling-ball simulation (Background: University of Oregon, n.d.) to calculate the acceleration of gravity on the Earth, Moon, and Mars.
The most general equation for displacement is a = s0 + V0t + (1/2)at2
where's = displacement after time t s0 = initial displacement (location at t = 0)
V0 = initial velocity (velocity at t = 0)
t = elapsed time in seconds
a = acceleration in m/s2
If the object starts at point s0 = 0 with initial velocity V0 = 0, then the equation becomes
s = (1/2)at2
Solving for a in terms of s and t, we get a = 2s/t2
For a freely falling object in a vacuum, a is the acceleration of gravity, g. If we record the time required for an object to fall a distance s in a time t, we can solve for g. Using the simulation, record the time required for the ball to fall 1, 2, 3, 4, 5, and 6 meters. Organize your results in a table, as follows (the first row has been completed for you). Round numbers to the nearest two decimals.

A phase change is what occurs when matter moves from one of these states to the other. The melting of ice into liquid water, for instance, constitutes a phase change, just as the boiling of water into invisible water vapor, or the condensing of gaseous water vapor in the air into liquid water on a cool windowpane or glass of water, are also phase changes. Phase changes generally require a
Physics of Swimming Swimming is a sport as well as exercise done in a water body which involves the movement of every body part and dragging the movement against the water body. Individuals practicing swimming wear swimming suits, which are specially designed form of clothes used while in water based activity (Haphaestus, B., 126). Swim suits help in reducing drag in water which in turn improves the propel lance in water. The
The important technical factor that makes cruise missiles soar over rocket-powered missiles is that, as it breathes air, it does not have to carry an oxidizer and thus its range is considerably longer compared to a rocket powered missile of equal weight. The rocket powered missile is the frontrunner on all other aspects. For example it travels much faster, it can fly low, it can have lower radar cross sections,
According to Newton, "To every action there is always opposed an equal reaction; or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts," (Zimmerman, 2008). In the act of pushing a pencil, the energy placed into pushing the pencil does not simply disappear with the writing. Most people write on flat, hard surfaces, such as wooden or acrylic desks. When these
