Question 26

A rider on a plastic sledge slides down a dry ski slope from point A (at the top) to point B (at the bottom).

State the main type of energy lost as the rider travels from A to B.

[1]

As the rider slides down, they become electrostatically charged and the lightweight nylon tassels on their safety helmet flare outwards in all directions.

The passage below explains how the rider becomes charged. Complete the passage using words from the box. Each word may be used once, more than once, or not at all.

\text{conduction} \quad \text{electrons} \quad \text{friction} \quad \text{negative} \quad \text{positive} \quad \text{protons}

The rider's suit becomes charged because of $\text{_______________}$ between the suit and the plastic slope.
During this process, negative charges called $\text{_______________}$ are transferred from the suit to the slope.
As a result, the rider's suit gains a $\text{_______________}$ charge.

[3]

Explain why the nylon tassels on the helmet flare outwards.

[2]

When the rider reaches the bottom, they grab a grounded metal safety rail and the tassels immediately collapse. Explain why the tassels collapse.
