A particle is located at position r relative to its axis of rotation. When a force F is applied to the particle, only the perpendicular component F⊥ produces a torque. This torque τ = r × F has magnitude τ = |r| |F⊥| = |r| |F| sin θ and is directed outward from the page. […]
Calculate the tension in the rope using the following equation: T = M x A. Four example, if you are trying to find T in a basic pulley system with an attached mass of 9g accelerating upwards at 2m/s² then T = 9g x 2m/s² = 18gm/s² or 18N (newtons). What is tension in pulley? […]
A loop in a circuit is any closed path along a circuit that does not encounter the same node more than once. The polarity of a voltage across an element changes the sign of the voltage in the sum of a loop. Is AP Physics 2 hard? In 2016, the AP Physics 2 exam remained […]
The weighted cart decreases in velocity because, as you add masses to it, it still has the same initial force that gives it motion (the explosion). Since this same force has to move a larger mass that has more inertia, the cart moves more slowly. Also, because this cart has increased in mass, its momentum […]
The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: fr = Fr/N. What is coefficient of friction physics? The coefficient of friction, µ, is a measure of […]
Period refers to the time for something to happen and is measured in seconds/cycle. In this case, there are 11 seconds per 33 vibrational cycles. Thus the period is (11 s) / (33 cycles) = 0.33 seconds. How do you find the period in AP Physics? What is the unit for period of motion? The […]

Calculate the force caused by gravity on the basic pulley system using the following equation: G = M x n (gravitational acceleration). The gravitational acceleration is a constant equal to 9.8 m/s². The mass M = 9g, so G = 9g x 9.8 m/s² = 88.2gm/s², or 88.2 newtons. How do you solve a pulley […]
Forces are vectors and have a direction and a magnitude. The force of gravity points straight down, but a ball rolling down a ramp doesn’t go straight down, it follows the ramp. Therefore, only the component of the gravitational force which points along the direction of the ball’s motion can accelerate the ball. Is a […]
Thin film interference can be both constructive and destructive. Constructive interference causes the light of a particular wavelength to increase in intensity. (It brightens a particular color like red, green, or blue.) Destructive interference causes the light of a particular frequency to decrease in intensity. What is thin-film interference in physics? Thin-film interference is the […]
Concave lens: The centre of the concave lens is thinner than the edges. Convex lens: The centre of the convex lens is thicker than the edges. Plano lens: One side of the Plano lens is flat and the other side is either concave or convex. What are the two types of lenses in physics? The […]
zero error Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, eg the needle on an ammeter failing to return to zero when no current flows. A zero error may result in a systematic uncertainty. Do you get an equation sheet for AP Physics […]
vox and voy are simply the horizontal and vertical components of the initial velocity vector. Also: remember that the acceleration in the horizontal direction is zero (ax = 0). Because there is no horizontal acceleration, the horizontal component of the velocity stays constant. How do you do projectile motion AP Physics? What are the 4 […]
The moment of inertia means the moment of mass with respect to an axis. In practical scenarios, we deal with both translation and rotational motion. The role of the moment of inertia in rotational motion is analogous to the role played by the mass in translational motion. How do you find the moment of inertia […]
Motion in two and three dimension Example: An ant moving on the top surface of a desk is example of two dimensional motion. Projectile and circular motion are examples of two dimensional motion. Motion in three dimension: Motion in space which incorporates all the X, Y and Z axis is called three dimensional motion. What […]
What happens if I am sick or have technical trouble taking my AP exam? Make up exams will be available for students who are sick or experience technical problems on test day. What happens if I am unable or do not want to take my AP exam? Students who cannot take their AP exam will […]
How do you calculate spring compression distance? What is the velocity of a spring at equilibrium? It moves through the equilibrium position of the vertical spring with its maximum velocity vmax = 1.5 m/s. Its velocity as a function of time is v(t) = -ωAsin(ωt + φ). How do you find the acceleration of a […]
Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge and lever. What are the 5 main simple machines? The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw. What is a simple machine in physics? A simple machine is a mechanical device that […]
Astrophysics is all about how the planets move, their placement, and how they effect our solar system, while Quantum Physics is about the movement of objects, their kinetic energy, and that “Quantum” comes from the Latin meaning “how much.” Is quantum physics taught in AP Physics? AP Physics 2 is a full-year course, equivalent to […]

For a student interested in computer science, they should probably take classes related to math and science. These would include AP Calculus AB and BC along with AP Physics. AP Statistics would also be useful to get an initial understanding of what statistics are like. Does physics go well with computer science? Physics and Computer […]
The egg dropped on the floor stops very quickly, which means the force on the egg is large, so it breaks. The egg dropped on the pillow slows down and stops more slowly since the pillow is squishy, therefore the force on the egg is smaller and the egg does not break. What is the […]
So to answer the titular question: you can probably be an engineer without taking AP Physics, but you might wish you had earned those credits in your 30-person high school class instead of your 300-person college lecture. Which AP physics should I take for engineering? AP recommends Physics C (along with AP Calculus AB or […]

Atwood’s machine is a common classroom demonstration used to illustrate principles of classical mechanics. What is the basic concept of the Atwood’s machine? An Atwood’s […]
The early suspension-bridge towers were stone, but now they are either steel or concrete. Next, the anchorages are built on both ends, usually of reinforced concrete with embedded steel eyebars to which the cables will be fastened. An eyebar is a length of metal with a hole (or “eye”) at the ends. What are the […]
