test next period....guess what i learned yesterday.....The integral is the area under the graph!!! so if J=S(Fdt) Then i can just find the area under a force vs time graph.....yup gonna be usin that on the test.
Now impulse. and hockey.
When catching a pass in hockey, experinced players know catch the puck. they must let their stick give to the puck, or slide the stick backwards as the puck hits it. Since the puck needs an impulse apllied to it to stop, the player can reduce the force of the stick on the puck by 'giving' to the pass. The impulse would be the same as if the player had held his stick still, but the time is prolonged and force reduced.
