The symbol for electric charge quantity is the capital letter “Q,” with the unit of coulombs abbreviated by the capital letter “C.” It so happens that the unit for electron flow, the amp, is equal to 1 coulomb of electrons passing by a given point in a circuit in 1 second of time. How do […]

The action and reaction forces are reciprocal (opposite) on an object. Examples may include: A swimmer swimming forward: The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. What are Newton’s 1st 2nd and 3rd laws of motion? In the first law, an object […]

Are NCERTs Enough For 10th, 12th Board Exams? In a word, No! But only for some subjects like physics, chemistry and mathematics or biology, which is why NCERT itself has brought additional books consisting of numerical problems called NCERT exemplar books. What is the most important question in physics? 1 – The origin of the […]

Increasing the number of cells increases the current in the circuit. What changes occur in the voltage in the circuit when increasing the number of cells? Increasing the number of cells increases the voltage (for cells in series the voltage is additive). How do you solve circuit problems in physics? When a charge of 8 […]

This is Newton’s Second Law – force on an object produces acceleration. The greater the mass, the sum of all matter in the skater’s body and equipment, the more force he must generate to accelerate down the track. How is physics used in ice skating? For the most part, the physics behind ice skating comes […]

Chunking refers to the process of taking individual pieces of information and grouping them into larger units. By grouping each data point into a larger whole, you can improve the amount of information you can remember. Probably the most common example of chunking occurs in phone numbers. Which of the following statements is consistent with […]

What is the easiest way to solve kinematic questions? What are the 4 kinematic formulas? There are four basic kinematics equations: v = v 0 + a t. Δ x = ( v + v 0 2 ) t. Δ x = v 0 t + 1 2 a t 2. v 2 = v […]

Eggs would produce the cracks when suffering from an impact energy of 12-26 mJ. Does the roller coaster ever get higher than the first hill Gizmo? Does the roller coaster ever get higher than the first hill? Explain. No, the first hill has the full potential as it goes it converts into kinetic. Gizmo Warm-up […]

In a free fall, weight of a body becomes effectively zero. How do you solve free fall physics problems? What is free fall in physics examples? An Object Exhibiting Projectile Motion. Fruit Falling from the Tree. Stone Dropped from a Hill. A Spacecraft in Continuous Orbit. Meteors Falling towards Earth. Sky Diving. Bungee Jumping. Shells […]

vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position. How do you solve vectors in […]

A change in momentum is known as an impulse. The vector quantity for impulse is represented by the letter “J”, and since it’s a change in momentum, its units can be one the same as those for momentum, [kg·m/s], and can also be written as a Newton-second [N·s]. How do you calculate impulse? Impulse Formula […]

The larger the mass, the larger the momentum, and the more force you need to change it. Mass does not make a roller coaster go faster but it does make it harder to slow down. This is why amusement parks test roller coasters with dummies filled with water. Does the roller coaster ever get higher […]

COLLISIONS IN A single game of American football have a similar force to that of 62 car crashes, according to new research. How much force is behind a football hit? But a DB’s mass combined with his speed — on average, 4.56 seconds for the 40-yard dash — can produce up to 1600 pounds of […]

Methods of Charging An uncharged object can be charged in three different ways as follows: Charging by friction ( triboelectric charging) Charging by conduction. Charging by induction. What are the three rules of charge interaction? The three rules for charge interactions are: oppositely-charged objects attract each other, like-charged objects repel each other, and a neutral […]

Newton’s third law simply states that for every action there is an equal and opposite reaction. So, if object A acts a force upon object B, then object B will exert an opposite yet equal force upon object A. Can you physically touch another person without that person touching you with the same magnitude? Answer […]

The three rules for charge interactions are: oppositely-charged objects attract each other, like-charged objects repel each other, and a neutral and a charged object attract each other. How do charges interact with each other physics? According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike […]

Cart on an Incline. Theory: As a laboratory cart goes up or down an inclined plane, it will be under the influence of two primary forces – gravity and friction. While it is comforting to consider only gravity, to fully understand the data one collects with a Motion Detector, you need to include friction in […]

Manage Your Time Effectively. The IGCSE assessment includes a variety of components and covers many subjects. Prepare Notes that Focus on Key Concepts. Prioritise the Subjects That are More Challenging For You. Practice as Often as Possible. How do you get full marks in Igcse physics? Take your studies into the real world. Have a […]

1) IGCSE Additional Mathematics Additional Mathematics is by far, through student consensus, the hardest IGCSE subject. It is not regular Mathematics, and has quite an extensive syllabus. Is physics hard in Igcse? Doing well on your IGCSE physics can often seem hard. You must put in an effort to do well and there aren’t too […]

You can use this information to calculate the thrill of each drop according to the definition: The thrill of a drop is the product of the angle of steepest descent in the drop (in radians) and the total vertical distance in the drop. The thrill of the coaster is the sum of the thrills of […]

When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity. Why does a rubber rod become negatively charged when rubbed with fur? Molecules in the fur have a stronger attraction […]

polarization, property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way. What is the formula of polarization? Polarization P in its quantitative meaning is the amount of dipole moment p per unit volume V of a polarized material, P = p/V. What is […]

On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. All moving objects possess kinetic energy, which is determined by the mass and speed of the object. How is […]

The smallest division of a 30-cm ruler is one millimeter, thus the uncertainty of the ruler is dx = 0.5mm = 0.05cm. For example, an object is measured to be x ± δx = (23.25 ± 0.05) cm. How do you solve uncertainty in physics? A common rule of thumb is to take one-half the […]
