Biomechanical Principles of Human Movement and Projectile Motion

These flashcards cover key vocabulary and concepts related to the biomechanical principles of human movement and projectile motion as discussed in the lecture.

Projectile Motion

The motion of an object when released into the air, determined by the object's height, angle, and speed of release.

Air Resistance

A force that acts against the horizontal motion of a projectile, affecting its velocity and distance traveled.

Projectile Motion

The motion of an object when released into the air, determined by the object's height, angle, and speed of release.

Air Resistance

A force that acts against the horizontal motion of a projectile, affecting its velocity and distance traveled.

Gravity

The downward force that accelerates objects towards the Earth at a rate of 9.81 m/s², influencing the trajectory of projectiles.

Trajectory

The path followed by a projectile in motion, influenced by its horizontal and vertical components.

Angle of Release

The angle at which a projectile is launched, affecting its trajectory shape and the distance it travels.

Optimal Angle of Release

The theoretical angle (usually 45°) that maximizes the distance for a projectile, assuming equal height of release and landing.

Vertical Component

The part of the projectile's motion that relates to its height and affects how high the projectile will go.

Horizontal Component

The part of the projectile's motion that relates to its horizontal distance traveled.

Height of Release

The elevation from which a projectile is launched, influencing the distance it can travel.

Mechanical Advantage

The ratio of output force to input force in a lever system, impacting the efficiency of movement.

Newton's 3 Laws of Motion

Three fundamental laws describing the relationships between the motion of an object and the forces acting on it.

Centre of Gravity

The point at which the weight of a body or system is concentrated, which affects stability and balance during movement.

Base of Support

The area beneath an object that provides stability; a larger base increases stability.

Line of Gravity

An imaginary line that extends from the center of gravity to the ground, critical for maintaining balance.
