Video TranscriptWhich term identifies a scalar quantity, acceleration, speed, momentum and displacement. We know that acceleration is a cost to course divided by mass. Also the vector quantity, then we can say exhalation is also a vector quantity. In option two, we have given speed. In option two we have given momentum. So momentum is a vector quantity because we know that momentum P is equals to mars into velocity velocity is a vector quantity. So we can say that momentum is also a vector quantity. Number 30. We have given speed. Speed is a scalar quantity. Okay, it is a scalar quantity Number four We have given displacement, displacement is a vector quantity, so the correct option will be speed. Show
Answer Verified Hint: There are two types of physical quantity. Scalar quantity and vector quantity. Scalar quantity is physical quantity which has magnitude but they don’t have direction. On the other hand vector quantities are the physical quantities which have both magnitude and direction. Among four given physical quantities see which of them have both magnitude and direction and which of them has only magnitude. Formula used: Complete step-by-step answer: Note: Every vector is represented by an arrowhead over the magnitude. i.e. if $A$ is the magnitude of a vector then it is represented by $\overrightarrow{A}$. Every vector obey the laws of vector addition and subtraction. If a quantity doesn’t obey vector addition is called scalar. So scalars are added algebraically.

Answer (Detailed Solution Below)Option 1 : Speed CONCEPT:
Examples: mass, speed, volume, work, time, power, energy, etc.
Examples: displacement, velocity, acceleration, force, momentum, torque, etc. EXPLANATION:
Let's discuss the concepts related to Laws of Motion and Newton's Laws of Motion. Explore more from Physics here. Learn now! Is acceleration a scalar quantity?In contrast to vectors, ordinary quantities that have a magnitude but not a direction are called scalars. For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars.
Which one is a scalar quantity?The correct answer is Pressure. A scalar quantity is defined as the physical quantity with magnitude and no direction. Mass, Speed, Distance, Time, Area, Volume, Density, Temperature are examples of Scalar Quantity.
Is momentum a scalar?While momentum and kinetic energy are compounded of the same two ingredients, mass and velocity, they are quite different concepts, and one aspect of their difference may be seen in the fact that momentum is a vector while energy is a scalar quantity.
Is acceleration and displacement a scalar quantity?The remainder of this lesson will focus on several examples of vector and scalar quantities (distance, displacement, speed, velocity, and acceleration).
