Projectile Motion and Energy

This page delves into horizontal and oblique projectile motion, as well as introducing concepts of momentum, impulse, work, power, and energy. These topics are crucial for understanding 11. sınıf fizik atışlar formülleri.

Horizontal projectile motion is described with equations for horizontal and vertical components:

Formula: x = vₓt (horizontal distance) Formula: h = 1/2 gt² (vertical displacement)

Oblique projectile motion is then explored, with equations for range and maximum height:

Formula: R = (v²/g) · sin(2θ) (range) Formula: h_max = (v² · sin²θ) / (2g) (maximum height)

Where v is initial velocity, g is gravitational acceleration, and θ is the launch angle.

Highlight: The maximum range for an oblique projectile occurs at a 45° launch angle.

The page concludes with brief introductions to momentum, impulse, work, power, and energy concepts:

Definition: Impulse is the change in momentum over time. Formula: W = F·d (Work is force multiplied by displacement) Formula: KE = 1/2 mv² (Kinetic energy) Formula: PE = mgh (Gravitational potential energy)

These formulas provide a foundation for understanding energy transformations in physical systems, a key concept in fizik 11.sınıf konu anlatımı pdf.

Free Fall and Vertical Motion

This page covers the fundamental concepts of free fall and vertical motion, essential topics in 11. Sınıf Fizik Konuları.

Free fall is characterized by constant acceleration due to gravity. The page presents key equations for displacement and velocity in free fall:

Formula: h = 1/2 gt²

Where h is height, g is gravitational acceleration (typically 10 m/s²), and t is time.

Highlight: In free fall, an object's displacement increases quadratically with time, following the sequence 5, 15, 25, 35 meters in successive seconds.

The concept of terminal velocity is introduced, where air resistance balances gravitational force:

Formula: F = k·A·v²

Where F is force, k is a coefficient, A is cross-sectional area, and v is velocity.

Vertical motion is then discussed, including upward and downward throws. The page presents velocity-time and position-time graphs for these motions.

Example: For an object thrown upward, the velocity decreases linearly with time until it reaches zero at the maximum height, then increases linearly as it falls back down.
