Law of Motion The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction. Point dynamics in a moving coordinate system Apparent forces The total force in a moving coordinate system can be found by subtracting the apparent forces from the forces working in the reference frame: The different apparent forces are give Dynamics of masspoint collections The centre of mass The velocity with respect to the centre of mass is given by The coordinates of the centre of mass are given by: In a 2-particle system, the coordinates of the centre of mas Bikes and Bee Problem Paul shows a simple solution to a classic problem involving the motion of a bee that flies to-and-fro between approaching bikes.
The Four Fundamental Forces of Physics Hank continues our series on the four fundamental forces of physics with a description of gravitation - the interaction by which physical bodies attract with a force proportional to that of their ma Projectile Motion Physics Tools for projectile motion Use this simple tool to solve physics problem related to projectile motion. You can use this tool for any projectile fired on ground level at an angle of theta de Projectile Motion — Projectile fired above the ground level Use this simple tool to solve physics problem related to projectile motion.
You can use this tool for any projectile fired above the ground level with initial velocity at horizontal direction. Solve physics problem related to collision between airliner and a bird Physics Tools for classical mechanics- Use this simple tool to solve physics problem related to collision between airliner and a bird Use this simple tool to solve physics problem related to collisio Solve problem related to object falling from rest As an object falls from rest, its gravitational potential energy is converted to kinetic energy.
Solve problem related to impact force from falling object As an object falls from rest, its gravitational potential energy is converted to kinetic energy. It illustrates what he saw as the problem of the Copenhagen interpreta How Does A Boomerang Work? A boomerang can execute its unique roundtrip flight by making use of three fundamental physics principles: Touch Screens and Quantum Tunnelling We look at the latest touch screen technology and how it uses the strange phenomenon of quantum tunnellingqI5q6OqSo4s.
Electromagnetism — Electrostatic Force: In this part, he teaches us about the electrostatic force, which builds up a charge in an object Electromagnetism — Magnetic Force: Cryogenic Experiments on Passive and Active Electronic Components In this episode, Shahriar investigates the theory and experimental results of the impact of extreme low temperatures on passive and active components.
This "bottle radio" take on a crystal radio requires no power source, operates on the power from radio waves, and receives signal from a long Water boils at room temperature once the pressure is low enough. What is interesting is that this decreases the temperature of t Effects of water pressure This clip illustrates the effects of water pressure on a ball filled with air. Heat conduction Heat conduction.
Wooden and metal pedestal stand in hot water. Since metal is a better heat conductor than wood, the ice cube on a metal pedestal melt faster than the ice cube on wooden pedestal We send O2 gas through a copper coil, which is then imm Distributed as part of a collaboration between NASA and However, only those possessing extreme skill can keep the water from falling out when the card is removed.
Variables and the names of variables Fundamentals of Fortran Computation Variables and the names of variables Integer A whole number. And for the experienced programmer this power and fle There is normally a STOP a In addition to calculating something simple like dividing up a re The system used in classical antiquity was slightly modified in the Middle Fermilab scientist Don Lincoln describes antimatter and its properties.
How do you search for it? Fermilab scientist Don Lincoln describes the concept of how the search for the Higgs boson is accomplished. Several large experimental groups are hot on the trail of this elusive subatomic particle An observer looking across a swimming pool at point C views a light ray An observer looking across a swimming pool at point C views a light ray coming from a point A on the opposition side of the pool at the bottom.
The ray leaves the water at a point 1. Light passes from air to another medium Light passes from air to another medium at point A. How long does it take the light ray to travel from A to B? Using the geometry we can find refract Snells Law Use this simple tool to solve physics problem related to simple light ray reflection problems. You can use this tool for light ray passes from a one medium to another. Call 1 Connect with an online tutor in under 5 minutes.
