Who invented the laws of motion of falling bodies and pendulum?
Well, no doubt many folk observed the swinging of a pendulum, for they are not uncommon even in nature. Huygens is credited with realizing the concept of a pendulum could be used to create a clock mechanism. This is particularly true for a small amount of swing. This discovery is sometimes credited to Galileo, but though he noticed that the length of pendulums (in his case, swinging lamps in the church!) was one variable of the time of the swing, he did not conceive of a clock mechanism.
Why the motion of simple pendulum is slow at equator?
A pendulum will swing slowest when closest to the equator. Why is this? The time period, T, of the swing of a pendulum is given by: T=2π√(l/g) where l is the length of the pendulum and g is acceleration due to gravity. Because the Earth is spinning, there is a bulge at the equator and the poles are slightly flattened. Hence on the equator the radius to the centre of the earth is greater than the radius at the poles. The equatorial radius is 6378.1km while the polar radius is 6356.8 km The value of g at the Earth's surface relates to the values of the Earth's radius, r, at that point using an inverse square law ie g is proportional to 1/r2 At the North Pole, g is about 9.83m/s2, while at the equator, g is smaller, at only 9.79m/s2 . So the period of a pendulum will be longer (i.e. slowest) at the equator than at the pole
What was created by Galileo?
Well Galileo Galilei didn't really create anything, but he discovered a lot. He discovered many celestial bodies as in Io, Europa, Ganymede, and Callisto, which all are some of Jupiter's moons. He also "started" discovering the Law of Inertia, which Isaac Newton later builds on. He also discovered the Law of the Pendulum and the Law of falling bodies. He also published many books.
What else moves like orbit?
Asteroids, comets and meteors move in orbits that obey Kepler's laws. A simple pendulum swings in an ellipse, in general (unless it has been started to swing in a plane). In this case the restoring force is proportional to distance from the centre for a small swing, and the pendulum orbits round the centre of the ellipse, unlike planets under the inverse-square law of gravity. Isaac Newton proved theoretically that the planets must move in ellipses with the Sun at one focus of the ellipse, and that's because of the laws of motion and the law of gravity.
What affects reactions the least size concentration temperature catalyst?
the experimental rate law of a simple reaction A->B+C is v=k[A].calculate the change in the reaction rate when:(a) the concentration of A is tripled (b) the concen-tration of A is halved
Rose's cuckoo clock is powered by a pendulum which she has to push gently to the right of left couple of days after it stops swinging. rose's clock is a perfect example of the fact that?
Rose's cuckoo clock demonstrates the principle of a pendulum's need to be reset periodically to maintain its motion. This is in line with the law of conservation of energy, which states that energy cannot be created or destroyed, but only transferred or transformed. The clock's reliance on the pendulum's swinging motion for power exemplifies the conversion of potential energy to kinetic energy, allowing the clock to function.
When was the law of the pendulum discovered?
The Knowledge regarding laws of pendulum started from Galileo around 1600 A.D.

A moving pendulum illustrates the change from potential energy to what?
A moving pendulum illustrates the change from potential energy to kinetic energy. In the process of its motion from its mean position to either of its extreme positions, the total energy remains constant, thus following the Law Of Conservation Of Energy.
Can you take the catalyst out your 2003 ford focus 2lt car?
No. It will NOT run right. You'll need a new converter. It's against the law, anyway!
When a ball drops where does the unused potential energy go when it is not transformed into kenetic energy?
It could be lost in the friction of the ball pushing air molecules out of the way. It could go into noise created by the air and ball. Could go into deforming the ball as the air resistance bends in slightly.
Can kinetic energy become potential energy?
Energy is never created or destroyed, but different forms of energy can be converted into another. For example, potential energy is the energy of position; a pendulum at the peak of its swing, or a spring tightly compressed. It can be converted into kinetic energy, for example, the pendulum swinging rapidly at the bottom of the swing, or the object propelled by the spring.
How much does a law clerk make in Canada?
A starting salary for a a law clerk is $40,000 - $50,000 annually.
How long should a pendulum be to have a period of one second?
The period depends on both the length of the pendulum and the force due to gravity. They are related by Huygen's law, T = 2π√(l/g). Assuming a gravity of 10Nkg-1 (roughly equal to Earth's 9.81 and a common approximation) it would need to be 2.5/pi2, or about 0.253099 metres.
Show how the period of oscillation relates to the velocity of the pendulum bob.?
Technically, in an ideal experiment, where there is lack of any opposing forces like air drag and friction, the period of oscillation of a pendulum only depends on the length of string (i.e, for r<<L). However, in presence of air drag, a force opposite to the velocity of the bob reduces the energy of oscillations, so it also changes the period of oscillations. acc to a law similar to stoke's law Fv = -bv where 'b' is a constant and depends on medium and the bob. So, the force acting on bob is the resultant of -w2x and -bv. this is how the period of oscillation depends on the velocity of pendulum bob.
Will law of energy conservation apply to simple pendulum?
Yes, The total amount of energy will always be constant. That is that GPE + KE = Total Energy - external forces(friction, sound, heat, etc.)
