Biomechanics Lecture – Acceleration & Momentum

Vocabulary flashcards covering key biomechanics terms from the lecture on acceleration, momentum, and their sporting applications.

Acceleration

The rate of change in velocity over time; calculated as A = (V₂ − V₁) / T.

Positive Acceleration

A situation where final velocity is higher than initial velocity.

Deceleration

Negative acceleration in which final velocity is lower than initial velocity.

Zero Acceleration

When there is no change in velocity; acceleration equals zero.

Velocity

Speed in a specific direction; a key factor in both acceleration and momentum.

Momentum

The product of an object’s mass and velocity (M = m × V); greater momentum makes an object harder to stop.

Mass

The amount of matter in an object; higher mass can increase momentum but requires more force for acceleration.

Power (Sport Performance)

The ability to produce force quickly; closely linked to an athlete’s capacity for rapid acceleration.

Agility

The ability to change direction rapidly; enhanced by faster acceleration when altering velocity.

Linear Motion

Movement in a straight path, such as a sprinter accelerating down the track.
