Rotational Motion

Part 1

When landing a triple axel (a figure skating jump where the skater rotates 3.5 times in the air before landing backwards), figure skaters often throw their arms and the leg they are not landing on far from their centre of gravity. This helps the skater land by:

Answer Section

• Increasing their moment of inertia, slowing down their angular velocity.

• Decreasing their moment of inertia, slowing down their angular velocity.

• Increasing their moment of inertia, speeding up their angular velocity.

• Decreasing their moment of inertia, speeding up their angular velocity.

• Showing the judges that they are in control, boosting their confidence.
