BIOMECHANICS

Motion

Movement occurs when an object changes position in space and time due to applied forces.

Linear motion

Movement along a straight or curved line with no rotation, where all body parts move in the same direction at the same speed.

Angular motion

Movement where all parts of a body move through a rotational pathway in the same direction and at the same time.

Projectile motion

Motion of an object propelled into the air or water, affected only by gravity and air resistance.

Speed

Measure of the distance an object travels per unit of time, indicating how quickly a distance is covered.

Velocity

Speed in a given direction, calculated by dividing displacement by time, representing changes in speed or direction.

Acceleration

Rate at which the velocity of a body changes with respect to time, with positive, negative, or zero acceleration.

Newton's Laws

Laws of motion including the Law of Inertia, Proportionality of Force and Acceleration, and Action and Reaction.

Balance

Ability to neutralize forces disturbing equilibrium, involving base of support, height of center of gravity, and mass.

Levers

Mechanical devices with an axis, resistance, and force, classified into three classes for force and speed multiplication.
