Overview of The Physics in Bobsledding - Physics Assignment Help

Assignment Task

Rationale

Bobsleigh is a team winter sport that involves making timed runs down narrow, twisting, banked ice tracks in a gravity-powered sleigh. Modern bobsled teams compete to complete a downhill route in the fastest times. As it is evident that a heavier bobsled and overall weight will result in a faster track time, the modern era of bobsledding has regulated that the maximum weight, including crew is 630kg for a 4-man crew, and 390kg for a 2-man crew. In the race, the only source of speed comes from the push-off at the start which is up to 50m by the crew before boarding to gain momentum down the track. Over the rest of the course, the bobsled’s velocity depends on the force generated from its weight and the friction from skating on the ice as well as the condition of the ice down the slope.

Quality of Evidence

The evidence supplied states that the increased mass of a bobsled will help to increase its speed down the track. This is a valid statement with sufficient evidence as more force downhill will increase terminal velocity as the factor of drag remains constant. It may be harder to overcome static friction at the start however it gains momentum down the track. Less air resistance means there will be a higher acceleration, and the bigger mass will create a larger force on the bobsled downhill. It is the same as having a soccer ball and a bowling ball and dropping them at the same time. The bowling ball would obviously hit the ground first as it has a larger mass and less drag on the ball pushing it up.
