How to solve pendulum physics problems How to find the amplitude of a pendulum The frequency of oscillation of a pendulum is 21 cycles per second. What is the period of oscillation? What would be the length of a 2 second pendulum?
From this, he concluded that freely falling objects experience uniform acceleration regardless of mass, as long as extraneous forces, such as air resistance and friction, can be minimized. But it was René Descartes, the great French philosopher, who would add new depth and dimension to inertial...
In fact, all the techniques I discuss here allow you to move, or lift, heavy objects by yourself, in many cases. The main principles of physics that are applied when moving heavy objects with relative ease are: Leverage and friction reduction. ...
Because it is moving at about 17,000 mph (28,000 km/h), the orbiter hits air molecules and builds up heat from friction (approximately 3000 degrees F, or 1650 degrees C). The orbiter is covered with ceramic insulating materials designed to protect it from this heat. The materials include...
The opposing aerodynamic force is drag, or the friction that resists the motion of an object moving through a fluid (or immobile in a moving fluid, as occurs when you fly a kite). If you stick your hand out of a car window while moving, you'll experience a very simple demonstration ...
In this way, it can avoid the friction caused by channel competition, and the retailer can adjust the pricing of both products to cover the market as much as possible. For the retailer, compared with direct selling, agent selling achieves more revenue; however, as already stated, the ...
This lets the collar and the gear synchronize their speeds before the teeth need to engage, like this image. HowStuffWorks The cone on the blue gear fits into the cone-shaped area in the collar, and friction between the cone and the collar synchronize the collar and the gear. The outer ...
Learn how to calculate kinetic friction and see examples that walk through sample problems step-by-step for you to improve your physics knowledge and skills.
Technology now enables us to design medicines on a computer, a process known as ‘rational’ drug design. By codifying our understanding of physics and molecular interactions into software, we can now find computational solutions to problems in medicine. This allows us to systematically predict new...
FrictionFriction is the force that opposes the motion when two surfaces in contact move or tend to move with respect to each other. It always acts opposite to the direction of motion, thus it is an opposing force.Answer and Explanation: There are different types of friction, such as- ...
