Differentiation is a process by which we can measure the rate of change of some quantity with respect to another quantity. These rates we get after differentiation are called derivatives. Suppose that we have a function y=f(x). Now, this is a function which has an independent variable x and a dependent variable y. How do […]

Work out the total momentum after the event (after the collision): Work out the total mass after the event (after the collision): Work out the new velocity: How do you solve momentum physics problems? What is an example of […]
With friction, there is both translational and rotational kinetic energy as the ball rolls down the ramp. When there is no slippage, the ball slides down the ramp with no rotation. “Special thanks to the University of Illinois NetMath Program and the mathematics department at William Fremd High School.” What are the physics behind bouncing […]
Brightness gets dimmer since less current or charge passing through each bulb AND smaller voltage drop across each bulb (the voltage gain at the battery is now distributed among 3 bulbs as opposed to just one). How do you solve circuit problems in physics? What is an electrical circuit physics? electric circuit, path for transmitting […]

When responding to this question, explain what action you would take and the thought process behind your decision. Your answer should show the potential employer that you can take a professional approach. Example: “If I noticed a mistake in my supervisor’s work, I would wait until I could speak with them privately. What is the […]
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. How […]

At the top of the hill, the cars have a great deal of gravitational potential energy, equal to the cars’ weight multiplied by the height of the hill. When the cars are released from the chain and begin coasting down the hill, potential energy transforms into kinetic energy until they reach the bottom of the […]
A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track. Does the roller coaster ever get higher […]
The intensity of a sound is the power of the sound in Watts divided by the area the sound covers in square meters. The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB). When the decibel level of traffic […]
How do you calculate the AMA or IMA of some simple machines? Calculating Mechanical Advantage and Efficiency of Simple Machines. In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr. […]
G-Force, an abbreviation for “Gravitational Force”, is a force that pulls or pushes on riders. On a roller coaster, it is caused when the vehicle has velocity on a curve (either vertical or horizontal). When the train is traveling up a hill, riders typically experience “positive g-forces”. Does the roller coaster ever get higher than […]
Navigate to “Options” on your examination. Let Students View Their Quiz Results โ This option lets learners see which choices were right by default. Allow students to view their quiz results. Students should see Correct Answers. How do I get GradPoint answers? Log into GradPoint. Click View for the (C) course in question. On the […]
As you ride a roller coaster, its wheels rub along the rails, creating heat as a result of friction. This friction slows the roller coaster gradually, as does the air that you fly through as you ride the ride. How does physics work with roller coasters? A roller coaster is a machine that uses gravity […]
The equation for the distance traveled by a projectile being affected by gravity is sin(2ฮธ)v2/g, where ฮธ is the angle, v is the initial velocity and g is acceleration due to gravity. How do you solve projectile problems in physics? What are the 3 types of projectiles? Three types of projectilesโ the bullet, the round […]

Solution : Light waves are electromagnetic waves, matter waves are probabilities waves. In vacuum light waves of different wavelength all have the same velocity . But , the velocity of matter waves of different wavelengths are different. What color has the highest frequency? Violet colour light has the highest frequency. The frequency of violet colour […]
The loop the loop is an example of conservation of energy. The three types of energy that we will be considering are: Work, Potential Energy, and Kinetic Energy. Work (W) is the energy given to the object by applying a force over a distance. Potential energy (PE) is the energy the object has due to […]
The weight of the hanging mass provides tension in the string, which helps to accelerate the cart along the track. A small frictional force will resist this motion. How did doubling the force affect the acceleration of the cart? The acceleration is equal to the net force divided by the mass. If the net force […]

Coulomb’s Law describes the force between two charged point-like particles: q1 * q2 F = k * ———- r^2 where k = Coulomb’s constant = 8.99 x 10^9 (N*m^2/C^2) q1 = charge on first particle (Coulombs) q2 = charge on second particle (Coulombs) r = distance between particles (meters) What is Coulomb’s law PDF? Coulomb’s […]
Theme park designer Brian Morrow explained that rollercoasters get faster throughout the day because they need to warm up earlier in the day, like a car. He told Mental Floss: “A coaster running in the morning could run slower when cooler. “The wheels are not as warm, the bearings are warming up. Does the roller […]
