Jennifer- Technology.
Limb Kinematics.
Limb Kinematics-a study of motion in relation to time and space.
pros- immediate, objective and accurate data.
cons- accuracy dependent on placements of body markers.
Wind Tunnel.
Wind Tunnel- air is drawn into the tunnel as it moves through it passes through screens to reduce turbulence and smoothen flow. as it narrows, airflow accelerates to the desired speed
pros- can teach a rider to reduce power required to ride at a certain velocity
cons- poor flow quality possible, high operating cost and noisy operation.
Force Plates.
Force Plates- an object that allows us to detect and measure the forces that are produced during physical exercise
pros- immediate, accurate and reliable results.
cons- specialist, expensive and usually based in labs.
Millie - Newton's Laws
Newton's Second Law
Newton’s law of acceleration states that a body’s rate of change of momentum is proportional to the size of the force applied and acts in the same direction as that force.
For example the harder the golfer hits the ball and the larger the mass of the club, the further the ball will travel.
Newton's Third Law
Newton’s third law is the law of reaction states’ for every action force applied to an object there is an equal and opposite reaction’.
The swimmer when tumble-turn against a wall pushes against the wall in a tumble-turn and the wall applies the force back to the swimmer who moves in the opposite direction of the action force.
The action force is applied as the muscles cause the skeletal system to apply force to the ground or surface involved. The surface will then apply the same force back onto the skeleton to create movement in the opposite direction.
Newton's First Law
Newton’s first law is the law of inertia which states that a body continues in a state of rest or uniform velocity unless/until acted upon by an external force. Inertia is the resistance an object has to change its state of motion. The larger the object or greater the mass of the object the greater the inertia.
When a force acts upon an object the rate of change of momentum experienced by the object is proportional to the size and direction of the force.
States that for every force there is an equal and opposite reaction force, meaning that as a diver pushes into the diving platform, the board will exert an equal and opposite force back to the diver.
