CBSE Class 11th Motion in a plane Details & Preparations Downloads
Motion is a fundamental aspect of the physical world, and when it occurs in two dimensions, it adds an extra layer of complexity and richness to our understanding. In this blog post, we will delve into the fascinating realm of "Motion in a Plane," exploring its principles, equations, and realworld applications.
What Is Motion in a Straight Line?
If an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. Motion in a straight line is nothing but linear motion. As the name suggests, it’s in a particular straight line, thus it can be said that it uses only one dimension.
2. Components of Motion:
In twodimensional motion, an object's motion can be broken down into horizontal (xaxis) and vertical (yaxis) components. The combination of these components determines the object's trajectory.
Equations of Motion in a Plane:
1. Position Vector:
The position of an object in a plane can be described using a position vector. r=xi^+yj^ , where i^ And j^ are unit vectors along the x and y axes, respectively, (x,y) represents the object's coordinates.
2. Displacement Vector:
The displacement vector d between two points A and B is given by D = rB  rA, representing both magnitude and direction.
3. Velocity and Acceleration:
The velocity vector is the rate of change of displacement, and acceleration a is the rate of change of velocity. These vectors have both magnitude and direction.
What is plane motion ?
Motion in a plane refers to the point where we consider motion in two dimensions as only two dimensions makes a plane. Here, considering the above, we take two axes into consideration – generally Xaxis or Y – axes. In an attempt to derive the equation of the motion in a plane, we must know about motion in one direction.
Equations of Plane Motion
The equations of motion in a straight line are:
v = u+at
s = ut+1/2 at²
v2 = u² + 2as
In a plane, we have to apply the same equations separately in both the directions: Y axis and Yaxis. This would give us the equations for motion in a plane.
vy = uy + ayt
sy = uy t +1/2 ay t²
v²y = u²y+2ay s
Where,

vy = final velocity of the particle in the ydirection

uy = initial velocity of the particle in the ydirection

sy = displacement of the particle in the ydirection

ay = acceleration of the particle in the ydirection
What is projectile motion ?
One of the most common examples of motion in a plane is Projectile motion. In a projectile motion, the only acceleration acting is in the vertical direction which is acceleration due to gravity (g). Therefore, equations of motion can be applied separately in the Xaxis and Yaxis to find the unknown parameters.
The above diagram represents the motion of an object under the influence of gravity. It is an example of projectile motion (a special case of motion in a plane).
Examples of TwoDimensional Plane Motion

Throwing a ball or a cannonball

The motion of a billiard ball on the billiard table.

A motion of a shell fired from a gun.

A motion of a boat in a river.

The motion of the earth around the sun.

SAMPLE PRACTICE QUESTIONS OF SIGNIFICANT FIGURES :
Q1. What is Motion in a Plane?
Answer: Motion in a plane refers to the movement of an object where its position is described by two coordinates (usually x and y) in a twodimensional space.
Q2. How is Motion in a Plane Different from Motion in a Straight Line?
Answer: Motion in a straight line occurs along a single dimension (usually the xaxis), while motion in a plane involves movement in two dimensions (both x and y axes).
Q3. What are the Two Components of Motion in a Plane?
Answer: Motion in a plane has two components: horizontal motion (along the xaxis) and vertical motion (along the yaxis).
Q4. How is Displacement Defined in Motion in a Plane?
Answer: Displacement in motion in a plane is a vector quantity defined by both magnitude and direction. It is the change in position from the initial to the final point.
Q5. What is Projectile Motion?
Answer: Projectile motion is a specific type of motion in a plane where an object is launched into the air and follows a curved path under the influence of gravity.
