Study Notes
Projectile Motion
Definition: Projectile motion is a type of motion in which an object moves under the influence of gravity, following a curved path.
Key Components:
- Horizontal motion: The object moves horizontally with a constant velocity.
- Vertical motion: The object is accelerated downward due to gravity, with a constant acceleration of 9.8 m/s^2 (on Earth).
Characteristics:
- Trajectory: The curved path followed by the projectile.
- Range: The maximum horizontal distance the projectile travels.
- Maximum height: The highest point reached by the projectile.
- Time of flight: The time it takes for the projectile to complete its trajectory.
Equations of Motion:
- Horizontal motion: x = v0x * t
- Vertical motion: y = v0y * t - 0.5 * g * t^2
- Range: R = v0x * t_flight
- Maximum height: h_max = v0y^2 / (2 * g)
Assumptions:
- Negligible air resistance: The motion is not affected by air resistance.
- Constant acceleration: Gravity is the only force acting on the projectile, with a constant acceleration of 9.8 m/s^2.
Types of Projectiles:
- Launched at an angle: Fired at an angle to the horizontal, with both horizontal and vertical components of velocity.
- Launched horizontally: Fired horizontally, with only a horizontal component of velocity.
- Dropped from rest: Released from rest, with only a vertical component of velocity.
Real-World Applications:
- Ballistics: The study of the trajectory of projectiles, such as bullets and artillery shells.
- Sports: The motion of balls, discs, and other projectiles in sports like basketball, football, and golf.
- Space Exploration: The motion of spacecraft and satellites in orbit around the Earth.
Projectile Motion
- Projectile motion is a type of motion where an object moves under the influence of gravity, following a curved path.
- The motion has two components: horizontal motion with a constant velocity, and vertical motion with a constant acceleration of 9.8 m/s^2 (on Earth).
Key Components
- Horizontal motion: constant velocity, no acceleration.
- Vertical motion: acceleration due to gravity (9.8 m/s^2 on Earth).
Characteristics
- Trajectory: curved path followed by the projectile.
- Range: maximum horizontal distance traveled by the projectile.
- Maximum height: highest point reached by the projectile.
- Time of flight: time taken to complete the trajectory.
Equations of Motion
- Horizontal motion: x = v0x × t.
- Vertical motion: y = v0y × t - 0.5 × g × t^2.
- Range: R = v0x × t_flight.
- Maximum height: h_max = v0y^2 / (2 × g).
Assumptions
- Negligible air resistance: no effect on the motion.
- Constant acceleration: gravity is the only force, with a constant acceleration of 9.8 m/s^2.
Types of Projectiles
- Launched at an angle: fired at an angle to the horizontal, with both horizontal and vertical components of velocity.
- Launched horizontally: fired horizontally, with only a horizontal component of velocity.
- Dropped from rest: released from rest, with only a vertical component of velocity.
Real-World Applications
- Ballistics: study of the trajectory of projectiles, such as bullets and artillery shells.
- Sports: motion of balls, discs, and other projectiles in sports like basketball, football, and golf.
- Space Exploration: motion of spacecraft and satellites in orbit around the Earth.
