In what sense is the Newtonian universe simpler than Ptolemy’s? Suppose observations had shown that the two did equally well at explaining the data. Construct an argument to say that Newton’s universe should still be preferred. The idea that the universe works mechanically, like a clock. It is called Newtonian, because it began from the Newtonian discovery of the laws of gravity and world motion.
According to the First Law of Thermodynamics, energy cannot be created or destroyed. There-fore, energy is not really lost, but may be released in another form such as heat or light. In this form, the energy may be partly unusable. (p. 28) 25. a. Ca, b. C, c. H, d. Fe, e. N, f. 0, g. K, h. Na (p. 29) 26. a.
2014. Retrieved from: http://www.britannica.com B. Compare and contrast electric force and magnetic force. B) With Electric force movement is the key, unlike magnetic force where it exists with stationary charges. With Magnetic force no movement is necessary in contrast to electric force.
For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account. 2. Inertia - A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force. 3. Potential Energy - Is the energy stored in an object due to its position in a force field or in a system due to its configuration.
must have constant velocity. must have zero momentum. 10. The inertial mass of a body may be defined as A. B. C. D. the ratio of the resultant force acting on the body to its acceleration.
REFLECTION JOURNAL Name: ____________Gladys Lima________________ Modules 3 & 4 Module 3: Natural Forces Affecting the Driver Date: ________________Janurary 28, 2013____________________ Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1.Gravity- The pull earth has on an object that makes it fall toward the center of the earth. 2. Inertia- a property of matter that stays in its state of rest or its speed along a straight line as long as it's not acted on by an outside force.
Don’t confuse mass and weight as mass is actually the amount of ‘stuff’ that makes up an object measured in kilograms. Weight is the force calculated by Weight (N) = Mass (kg) x Gravitational field strength (N/kg) W m The gravitational field strength on Earth is taken as 10N/kg. A resultant force is the sum of forces acting on an object. 2N 4N 4N Resultant force = 2N + 4N = 6N to the right g 2N
The cart causes the supporting structure to flex, bend and vibrate and producing kinetic energy but not on the cart but on the track. The conservation of energy illustrates work and energy relationships. It states that the work done by external forces changes the amount of mechanical energy. Energy cannot be created or destroyed and it remains constant. The conservation of energy in the case of a roller coaster demonstrates that when a cart reaches its initial summit only force is gravity.
It was assumed by Newton that the orbit of the moon was due to the same reason that the projectile would never land. This theory was called “Principia” (Fowler). All of the studies done with projectiles contributed to Isaac Newton’s three laws of motion. His first law stated that an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Using mathematics, he showed that a single force keeps the planets in their orbit around the sun. He called this force gravity and then created Newton’s law of Motion. Law one states that an object at rest will remain at rest, and an object in motion will remain in motion, at a constant speed unless or until outside forces act upon it .Law two states that the net force acting upon an object is a product of its mass multiplied by its acceleration. Law three states that when one object exerts a force on another, the second object exerts on the first a force equal in magnitude but opposite in
