Why is sweeping in curling necessary? Isn’t the ice-sheet clean enough?
In: Physics
it’s extremely difficult for the thrower to have the exact distance and direction to make a rock stop at a precise location. You are throwing from about 120 feet away from your target.
In high level curling, there are times where your shot needs to be very precise (within millimeters of target) to be useful.
Sweeping allows the team to control the rock to a certain degree.
There’s nothing that can be done if the rock is thrown too hard, but based on the sweeping technique used, sweeping could cause the rock to travel further down the sheet, travel straighter, or curl more than an unswept rock.
