Linear Kinematics III

A set of flashcards covering the key concepts of linear kinematics, specifically focusing on projectile motion and its associated factors.

Projectile Motion

Refers to any object moving in the air acted upon by gravity and air resistance.

Gravity

The force that results in constant vertical acceleration due to the attraction between two masses.

Trajectory

The flight path of a projectile.

Apex

The highest point in the trajectory of a projectile.

Parabola

A curve that is symmetrical about an axis through its highest point.

Projection Angle

The angle at which an object is projected into the air, varying from 0° to 90°.

Resultant Velocity

The combined effect of vertical and horizontal velocity components at the moment of release.

Vertical Velocity

The component of velocity that changes due to gravity at a rate of -9.81 m/s².

Horizontal Velocity

The component of velocity that remains constant during flight, until it hits the ground.

Projection Height

The difference in height between the vertical takeoff position and the vertical landing position.

Equations of Uniformly Accelerated Motion

Mathematical formulas that describe the motion of objects under constant acceleration.

Time of Flight

The total time an object remains in the air during its projectile motion.

Horizontal Range

The horizontal distance traveled by the projectile.

Vertical Displacement

The change in vertical position of the projectile over time.

Takeoff Velocity

The initial velocity of a projectile at the moment of release.
