4. Biomechanical Principles Equations Flashcards
What is the equation for force?
Force = mass x acceleration
What is the equation for torque
Force x lever arm
What is the equation for speed?
Speed = distance / time
What is the equation for velocity?
Velocity = displacement / time
What is the equation for angular speed?
Angular distance (degrees) / time
What is the equation for angular velocity?
Angular velocity = angular displacement (degrees) / time
What is the equation for acceleration?
Acceleration = change in velocity / change in time
What is the equation for angular acceleration?
Angular acceleration = change in angular velocity / change in time
What is the equation for momentum?
Momentum = mass x velocity
What is the equation for moment of inertia?
Moment of inertia = mass x radius^2
What is the equation for angular momentum?
Angular momentum = moment of inertia x angular velocity
What is the equation for impulse?
Impulse= force x time
What is the equation for mechanical advantage?
Mechanical advantage = force arm / resistance arm
What is the equation for linear speed of a lever?
Linear speed = angular velocity / moment arm
