Study Notes
Dynamics of Rigid Bodies
- Course topics include introduction, uniform rectilinear motion, motion in a curved path, kinetics of rigid bodies, kinematics of rigid bodies, rotation of rigid bodies, and plane motion of rigid bodies.
Motion in a Curved Path
- Subtopics include flight of a projectile and tangential and normal components of acceleration.
Flight of a Projectile
- A projectile is an object thrown into space with only gravity acting on it.
- The trajectory of a projectile is the path it follows, which is a parabola without air resistance.
- Initial velocity (u) is the velocity with which the projectile is launched.
- Horizontal component (ux) is ucosθ, and vertical component (uy) is usinθ.
Formulas
- Vertical velocity (vy) is uy - g⋅t.
- Time of flight (T) is 2usinθ/g.
- Maximum height (H) is u²sin²θ / 2g.
- Range (R) is u²sin²θ / g.
- Maximum range is achieved at an angle of 45°.
Motion Equations
- Horizontal distance (x) is ux⋅t.
- Vertical distance (y) is uy⋅t - gt².
This quiz covers the basics of projectile motion, neglecting air resistance, and its applications in real-world scenarios.
