the physics behind hurlding
Newton’s First Law of Motion:
The general Newton’s First Law of motion states that an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force. When examining a hurdle race it is clear that Newton’s First law of motion is present. When a hurdler is in the blocks, they are at rest. The hurdler will only begin to move when a force is exerted coming out of the blocks. Newton’s First law is also seen during the race. When the hurdler is running, the property of inertia is acting on them. This makes it harder for the hurdler to accelerate throughout the race
Newton’s Second Law of Motion:
Newton’s Second Law of Motion states that the acceleration of an object is inversely proportional to the mass of that object and that force is equal to mass multiplied by acceleration. In terms of hurdling, this means that hurdlers that have more mass will have to exert more force in order to accelerate at the speed that a hurdler with less mass.
Newton’s Third Law of Motion:
Newton’s Third Law of motion states that for every action there is an equal and opposite reaction. In the beginning of the race the hurdler exerts a certain force on the blocks and the same force is exerted on them, allowing for a good start. From a hurdling perspective, when a hurdler pushes off the ground with a certain force, the same force that the hurdler pushed off the ground with will propel them over the hurdler allowing them to clear it.
