Sport Application and Newton’s Laws of Motion

1 st Law Every body persists in its state of rest or of uniform motion in a straight line unless it is compelled to change that state by forces impressed on it OR A body remains at rest or in a state of uniform motion in a straight line unless acted upon by an applied force. This is also described as the Law of Inertia because it describes the quality of needing a force to change the state of rest or motion

2 nd Law The change of motion is proportional to the motive power impressed, and is made in the direction of the right(straight) line in which the force is impressed. Or If a body of mass(m) has an acceleration(a), the force acting on it is (f), defined as the product of its mass and acceleration (F=ma) Law of Acceleration-the acceleration of an object that is acted upon by a force is directly proportional to the force and inversely proportional to the mass of the object

3 rd Law To every action there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal and directed to contrary parts Or To every action there is an equal and opposite reaction Law of Action-Reaction

Classes of Levers and Lever Systems The lever system consists of an axis of rotation- Fulcrum(joints) around which a rigid lever(bones) move, by a force(muscle) The system consists of a 1. Force Arm- applied force- external force, weight, object 2. Resistance Arm-resists motion (resistive force- muscle force) 3. Fulcrum - axis of rotation There are 3 classes of lever they are classified according to the positions of the axis, force arm and resistance arm

1 st Class the Fulcrum is in the middle between the force and the resistance ___________________________ Force Resistance Fulcrum This lever favors SPEED or FORCE depending on the relative length of the force and resistance arms.

2 nd Class Resistance is in the middle between the fulcrum and the force Applied Resistance ___________________________ Fulcrum Applied Force Range of Motion is sacrificed to gain FORCE Output. Resistance arm is always longer than the Force arm

3 rd Class Applied Resistance is in the middle between the fulcrum and the Applied Force The Force arm is always longer than the arm. Therefore this favors SPEED over FORCE. Applied Force _________________________ Fulcrum Applied Resistance
