IB Sports Exercise Chapter 4 Revision
Exam Questions Answered Correctly.
Flexion - Answer Closing of the joint angle around the transverse axis
Extension - Answer Opening of the joint angle around the transverse axis at the joint
Newton's 1st Law - Answer An object in motion will stay in motion until acted upon by an unbalanced
force (inertia).
Abduction - Answer Opening of the joint angle around the anteroposterior axis at the joint
Inertia - Answer A tendency to do nothing or to remain unchanged.
Center of Gravity - Answer is the average location of the weight of an object.
Center of Mass - Answer distribution of mass in space is the unique point where the weighted relative
position of the distributed mass sums to zero or the point where if a force is applied causes it to move in
direction of force without rotation.
Type 2b - Answer Motor units generate the fastest contraction times and largest forces, but these
fatigue at a high rate and so cannot maintain contractions for a long period of time.
Type 2a - Answer Fast twitch oxidative motor units consist of mainly type 2a muscle fibers. Fast neural
transmission times and stronger contraction forces and are also resistant to fatigue.
Type 1 - Answer Slow twitch motor units mainly consist of type 1 muscle fibres. Slow nerve
transmission speeds, small forces, fatigue resistant.
, Angular Acceleration - Answer change of angular velocity divided by the time taken for the change to
take place - Measured degrees/radians per second per second
Weight - Answer effect of the force of gravity on mass
Mass - Answer amount of material in a body or object
Linear Displacement - Answer movement in one direction along a single axis
Angular Velocity - Answer change of angular displacement divided by the time taken - Measured
degrees per second or radians per second.
Gravity - Answer attractive force between objects related to
their mass
Force - Answer the mechanical interaction that goes on between two objects
Angular Displacement - Answer difference between start and end positions when a body moves around
an axis with angular motion - Measured in degrees or radians
Surface Drag - Answer Caused by the interaction between surface of the body or object and the fluid
molecules (Affected by: velocity, surface area, nature
Drag Force - Answer Moving through a resistive force
Torque - Answer The moment of a force or system of forces tending to cause rotation.
Momentum - Answer The mass of an object x its velocity.
Impulse - Answer When a person applies force over a certain time.
