Linear Energy and Kinetics

These flashcards cover key concepts related to linear energy, kinematics, kinetics, and their applications in biomechanics.

Kinematics

The study of motion in terms of spatial and temporal components; includes linear position, velocity, and acceleration.

Kinetics

The study of the causes of motion, focusing on forces, torque, impulse, momentum, work, power, and energy.

Mechanical Energy

The capacity to do work; includes kinetic, gravitational potential, and potential strain energy.

Kinetic Energy (KE)

Energy from the motion of an object, calculated as KE = 1/2 mv^2.

Potential Energy (PE)

Stored energy based on an object's position; gravitational potential energy calculated as PEg = mgh.

Work-Energy Relationship

The principle stating that work done is equal to the change in an object's energy.

Hooke's Law

A principle stating that the force exerted by a spring is proportional to its displacement; Fs = -k∆x.

Spring Constant (k)

A measure of a spring's stiffness, expressed in N/m.

Units of Energy

Energy is measured in Joules, where 1 Joule is equivalent to 1 Newton meter (J = Nm).

Impulse

Change in momentum produced by a force acting over a period of time.
