## Important Topics for DC Pandey Mechanics Part 1 Solutions Chapter 4: Projectile Motion

Projectile Motion

When a body or a particle is acted upon with a constant force such that the angle is Ө (not equal to 0 or 180°) with the direction of its initial velocity (not equal to 0), the path that is followed by the particle is termed to be a parabola and the motion of the body or the particle is termed as projectile motion.

Projectile motion falls under the category of two-dimensional motions which means that the motion of the particle is constrained to a plane. This motion has a constant acceleration.

Relative Motion Between Two Projectiles

In DC Pandey Projective Motion chapter, you will learn about relative motion between two projectiles and the fundamentals related to the phenomenon. You will also get to know that the relative acceleration between two projectiles in 0 and there is always uniform relative motion between them.

The chapter also explains the relationship between the velocity of the two projectiles and their respective components. The algebraic formulas have been derived and explained with all the components like speed, height and displacement.

Projectile Motion in Inclined Plane

You will come across different scenarios where projectile motion occurs and the fundamentals of motion depending on those situations. The two cases that will be discussed in the chapter are

• Up the plane – where the direction of the x-axis is in the upward direction of the plane and y is in a perpendicular direction.
• Down the plane – where both x and y are down the plane and also perpendicular to the plane.

With the help of these, you will learn to formulate equations and determine the range, time of flight, displacement and a maximum height of the body or particle in motion. These concepts have been explained with examples in the chapter and have been used in solving numerical questions in the chapter. You will also learn to determine the maximum and minimum range for displacement and equate them with the formulas and values from the exercises.

### Exercise-wise Discussions of DC Pandey Mechanics Part 1 Chapter 4: Projectile Motion

Introductory Exercise 4.1
