FAQs on Projectile Motion Video Lecture - Engineering Mechanics - Civil Engineering (CE)

1. What is projectile motion?
Ans. Projectile motion refers to the motion of an object that is projected into the air and follows a curved path due to the influence of gravity. It is a type of motion where the object moves both horizontally and vertically.
2. How is the trajectory of a projectile determined?
Ans. The trajectory of a projectile is determined by its initial velocity, angle of projection, and the acceleration due to gravity. By considering these factors, we can calculate the path of the projectile and predict its motion.
3. What are the two components of projectile motion?
Ans. Projectile motion can be divided into two components: horizontal motion and vertical motion. The horizontal component is constant and unaffected by gravity, while the vertical component is influenced by gravity and follows a parabolic path.
4. How does the angle of projection affect the range of a projectile?
Ans. The angle of projection significantly affects the range of a projectile. For a given initial velocity, the range is maximum when the angle of projection is 45 degrees. If the angle is less than 45 degrees, the range decreases, and if it is greater than 45 degrees, the range also decreases.
5. What are some real-life examples of projectile motion?
Ans. Projectile motion can be observed in various real-life scenarios. Some examples include the motion of a basketball being thrown into a hoop, a baseball being hit by a bat, a cannonball being fired, or a rocket being launched into space. In all these cases, the objects follow a curved path due to the influence of gravity.
