What is the impulse lab in space exploration?
Impulse Lab Impulse Lab In this lab you will use your fire extinguisher to give astronaut Wally different impulses. For each impulse you are to determine Wally’s speed and/or momentum as he passes between the two photogates that are 10 meters apart.

physics aviary photoelectric effect
What are the three characteristics of the photoelectric effect?
The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics.
What are the experimental observations of photoelectric effect?
Experimental observations of photoelectric emission. The theory of the source of photoelectric effect must explain the experimental observations of the emission of electrons from an illuminated metal surface. For a given metal surface, there exists a certain minimum frequency of incident radiation below which no photoelectrons are emitted.
How does the photoelectric effect affect spacecrafts?
The photoelectric effect will cause spacecraft exposed to sunlight to develop a positive charge. This can be a major problem, as other parts of the spacecraft are in shadow which will result in the spacecraft developing a negative charge from nearby plasmas.
How does the photoelectric effect affect X-ray waves?
the electron is tightly bound (as in K shell) The electron that is removed is then called a photoelectron and the incident photon is completely absorbed in the process. Hence, the photoelectric effect contributes to the attenuation of the x-ray beam as it passes through matter.
physics aviary kinetic energy
Is the kinetic energy of an object invariant?
Like any physical quantity that is a function of velocity, the kinetic energy of an object depends on the relationship between the object and the observer’s frame of reference. Thus, the kinetic energy of an object is not invariant .
physics aviary circular motion
What are the dynamics of circular motion?
In this topic, we will learn about the dynamics of circular motion with its application. It is very important to understand two basic forces while learning circular motion. They are the centripetal force and centrifugal force. These two forces form the foundation of circular motion.
physics aviary kinetic energy
What is relativistic kinetic energy?
Relativistic kinetic energy of rigid bodies. So, the total energy can be partitioned into the rest mass energy plus the Newtonian kinetic energy at low speeds. When objects move at a speed much slower than light (e.g. in everyday phenomena on Earth), the first two terms of the series predominate.
physics aviary circular motion
What is the circular motion of a car on a road?
The circular motion of any car in either a flat or a banked road provides interesting applications of the laws of motion. This equation can be written as It is possible to decrease the contribution of the friction to the circular motion of a car moving in the road provided the road is banked.
