Scalar quantity - Study guides, Class notes & Summaries

AC HPAT Physics Exam Solved 100% Correct!! DIstance · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direction ...

Program Consists of instructions executing one at a time. Input A program gets data, perhaps from a file, keyboard, touchscreen, network, etc. Brainpower 0:02 / 0:15 Process A programs performs computations on that data, such as adding two values like x + y. Output A programs puts that data somewhere, such as to a file, screen, network, etc. Computational thinking Creating a sequence of instructions to solve a problem. Algorithm A sequence of instruct...

What is a scalar quantity? - Answer One that has magnitude (size) only. What is a vector quantity? - Answer One that has magnitude (size) and direction. These are examples of scalar quantaties: - Answer Distance, speed, mass, energy. These are examples of vector quantaties: - Answer Displacement, velocity, acceleration, force, weight, momentum. What is velocity? - Answer Speed in a given direction. What is the equation for (average) speed? - Answer Distance trave...

Honors Physics - Final Exam Review with Complete Solutions What is the principle of superposition in wave interference? The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves' amplitudes. How does the frequency of a wave relate to its wavelength? The frequency of a wave is inversely related to its wavelength; as the frequency increases, the wavelength decreases, and vice versa. What is the role of an ele...

Honors Physics Final Exam Questions and Answers Graded A+ What is the principle of inertia? The principle of inertia states that an object will not change its state of motion unless acted upon by an external force. How does friction affect the motion of an object? Friction opposes the motion of an object, causing it to slow down or stop. What is the concept of momentum? Momentum is the quantity of motion an object has, which depends on its mass and velocity. What is the dif...

scalar - correct answer quantity that represents only magnitude, e.g., time, temperature, or volume. It is expressed using a single number, including any units. vector - correct answer quantity that represents magnitude and direction. It is commonly used to represent displacement, velocity, acceleration, or force. Displacement (s) - correct answer the distance and direction of a body's movement (an airplane flies east 100 nm). Velocity (V) - correct answer the speed and directi...

Velocity Vector. Speed and direction. Displacement divided by time. Acceleration Vector. Rate of change ...

Scalar - Answer quantities with only magnitude such as speed, distance, time and mass. Vector - Answer quantities with a magnitude and direction e.g. acceleration, force momentum and weight. A vector quantity can be represented as an arrow, the size representing the magnitude and the direction, the direction. Non-contact force - Answer the objects are physically separate e.g. magnetism/gravity/electrostatic. 3 non-contact forces - Answer magnetism gravity electrostati...

Vector - correct answer A quantity that involves both magnitude and direction Scalar - correct answer A quantity that does not involve direction; Only has magnitude Magnitude of a Vector - correct answer |A| or ||A||=√((Ax)^2+(Ay)^2) Angle or Direction of a vector - correct answer θ=tan⁻¹(Ay/Ax) Dot product - correct answer The multiplication of two vectors which results in a scalar. A·B=|A||B|cosθ=AxBx+AyBy Cross product - correct answer The multiplication of two vectors ...
