Energy Changes in a System
1. This question has 4 part(s).
1.1. Figure 1 shows a water slide called Verti-go at the water park, Aqualandia, in Spain.
Water is pumped down the slide to make the rider go faster.
Slide 1 is 28 m tall, and Slide 2 is 33 m tall.
This type of slide is called a 'freefall' water slide.
Suggest why it is given this name.
1.2. What is the purpose of the water being pumped down the slide?
Tick (✓) two boxes.
To keep the riders cool in the sun | |
To decrease friction | |
To increase the gravitational potential energy of the riders | |
To increase the speed of the riders | |
To decrease the kinetic energy of the riders |
1.3. The mass of one rider on Slide 2 is 50 kg.
Calculate the change in gravitational potential energy as they climb the stairs and stand at the top of the slide, giving the units.
1.4. Determine how much more gravitational potential energy the rider from part (c) has on Slide 2 than if they rode on Slide 1.
