Project on Projectile Motion
Objective
To study and analyze the motion of a projectile and understand the concepts of horizontal and vertical
components, range, time of flight, and maximum height.
Introduction
Projectile motion is a form of motion in which an object moves in a curved trajectory under the influence of
gravity. The path followed by a projectile is called its trajectory. It involves two motions:
- Horizontal motion with constant velocity
- Vertical motion with uniform acceleration (due to gravity)
Principle of Independence of Motions
Projectile motion is a result of two independent motions:
- Horizontal Motion (Uniform motion)
- Vertical Motion (Uniformly accelerated motion)
Key Equations
1. Time of Flight (T):
T = (2u sin(theta)) / g
2. Maximum Height (H):
H = (u^2 sin^2(theta)) / (2g)
3. Horizontal Range (R):
R = (u^2 sin(2theta)) / g
Where:
- u = initial velocity
- theta = angle of projection
- g = acceleration due to gravity (9.8 m/s^2)

Experimental Setup
Materials Required:
- Protractor
- Stopwatch
- Small ball or marble
- Ruler or measuring tape
- Inclined ramp or launcher
- Graph paper
Procedure:
1. Launch a ball at an angle using the ramp.
2. Record the time of flight using a stopwatch.
3. Measure horizontal range.
4. Repeat the experiment for different angles.
5. Plot a graph of range vs. angle.
Expected Observations
- The range is maximum at 45 degrees.
- Symmetrical range for angles like 30 and 60 degrees.
- As the angle increases beyond 45 degrees, the range decreases.
Conclusion
Projectile motion illustrates the independence of horizontal and vertical motions. It can be analyzed using
basic kinematic equations and is applicable in various real-life scenarios like sports, ballistics, and
engineering.
Applications
- Launching satellites
- Sports (e.g., football, basketball)
Project on Projectile Motion
- Fireworks and military projectiles
