Motion in Uniform Gravitational Field
This page delves into the analysis of motion in a uniform gravitational field, which is a common topic in Lois de Newton Exercices corrigés PDF terminale s.
Equations of Motion
The document derives the equations of motion for an object in a uniform gravitational field:
- Define the system and choose a reference frame.
- Apply Newton's Second Law: ΣF = ma
- Solve for acceleration components: ax = 0, ay = -g, az = 0
- Integrate to find velocity and position equations.
Example: For a projectile launched at an angle α with initial velocity v0: x = v0 cos(α) t y = -1/2 gt² + v0 sin(α) t
These equations are fundamental for solving Mouvement dans un champ uniforme exercices corrigés Terminale problems.
Trajectory Analysis
The page includes a diagram showing the parabolic trajectory of a projectile, illustrating key points such as the maximum height and range.
Highlight: The trajectory of a projectile in a uniform gravitational field is always parabolic, neglecting air resistance.
This analysis is crucial for understanding Exercice TYPE BAC Mouvement dans un champ uniforme questions.
