General Knowledge
The study of forces and their effects on humans participating in exercise or sports
What is sport & exercise biomechanics?
Also referred to as translation. This is when a system moves in the same direction at the same time
What is linear motion?
The turning effect cause by a force rotating about an axis
What is torque?
The SI unit for work
What is a Joule (J)?
The potential energy of an object stored as a result of deformation
What is strain energy?
The branch of mechanics in which sport & exercise biomechanics resides
What is rigid-body mechanics?
The distance measured between initial and final positions of a system
What is resultant displacement?
The capability of a system to resist rotational changes in motion
What is angular inertia?
The capacity to do work
What is energy?
This occurs as a result of a change in the length of an object
What is linear strain?
Born on Christmas Day, this student is well-known for his contributions to our current understanding of mathematics as it pertains to physics
Who is Isaac Newton?
This force accelerates a projectile in the vertical position
What is gravitational force?
The product of moment of inertia & angular velocity. Quantifies angular motion
What is angular momentum?
This is completed when a system is displaced in the opposite direction of the applied force
What is negative work?
Tension, compression & even shear stress are all examples of this. The force may act parallel or perpendicular to the plane of analysis
What is a uniaxial, or simple, stress?
The forces responsible for motion & change of position in humans
What are external forces?
This collision results in the colliding systems stay together one another and then follow the same line of action at the same velocity
What is an inelastic collision?
This line is perpendicular to the tangent line, drawn from the tangent line to the middle of the circle
What is the radial line?
This decreases with increased duration of an activity
What is power output?
This is shown at the point in which a biological material sustains a rupture due to an overload
What is failure strength or failure strain?
The formula for dynamic friction force
What is Fd = 𝜇dR ?
The formula for a three object system
What is Li = Σ(mu) = m1u1 + m2u2 + m3u3 = m1v1 + m2v2 + m3v3 = Σ(mv) = Lf ?
Unlike in linear kinetics, this law does not require angular velocity to be constant
What is Newton's first law?
The formula for gravitational potential energy
What is PE = Wh or PE = mgh?
A larger depth & object width (radius) aids is resisting this type of load
What is torsion load?
