Class 11 Motion In A Plane Mind Map: The motion in a plane chapter in CBSE class 11 physics deals with the motion of objects in two dimensions. The chapter covers topics like vectors and scalars, position vector, displacement, velocity, acceleration, projectile motion, uniform circular motion, etc. Revising all these topics is going to be a super quick task as we have presented for you the mind map of CBSE Class 11 Physics Chapter – Motion in a Plane here. You will be able to recall all the essential information with the help of well-structured and attractively interlinked pictures. As the visuals are often considered more appealing than the written formats, revision done with the help of a mind map will help you retain the information for a more extended period of time. The mind map for CBS Class 11 Physics Chapter 3 – Motion In A Plane is according to the revised syllabus and covers all important concepts and formulas. You can see as well as download the mind map in PDF from the link mentioned here in this article.
Check major topics discussed in ‘Motion In A Plane’ below:
1.Scalar quantities are quantities with magnitudes only. Examples are distance, speed, mass and temperature.
2.Vector quantities are quantities with magnitude and direction both.
Example: displacement, velocity and acceleration.
3.A vector A multiplied by a real number λ is also a vector, whose magnitude is λ times the magnitude of the vector A and whose direction is the same or opposite depending upon whether λ is positive or negative.
4.Two vectors A and B may be added graphically using head-to-tail method or parallelogram method.
5.Vector addition is commutative.
i.e., A + B = B + A
It also obeys the associative law.
i.e., (A + B) + C = A + (B + C)
6.A null or zero vector is a vector with zero magnitude. Since the magnitude is zero, we don’t have to specify its direction. It has the properties :
A + 0 = A
λ0 = 0
0 A = 0
7.The subtraction of vector B from A is defined as the sum of A and –B:
i.e., A – B = A+ (–B)
8.A vector A can be resolved into component along two given vectors a and b lying in the same plane.
A = λ a + µ b, where λ and µ are real numbers.
9.A unit vector associated with a vector A has magnitude 1 and is along the vector A.
10.The position vector of an object in x-y plane is given by r = xi + yj and the displacement from position r to position r’ is given by
Δr = r’ – r
