When [blank_start]meteors[blank_end] and [blank_start]space[blank_end] [blank_start]shuttles[blank_end] enter the atmosphere, they have a very [blank_start]high[blank_end] [blank_start]kinetic[blank_end] energy. Due to [blank_start]collisions[blank_end] with particles in the atmosphere, some of the [blank_start]kinetic[blank_end] energy is transferred to [blank_start]heat[blank_end] energy, and [blank_start]work[blank_end] is [blank_start]done[blank_end]. The temperatures become so [blank_start]high[blank_end] that most [blank_start]meteors[blank_end] burn up; but [blank_start]space[blank_end] [blank_start]shuttles[blank_end] have heat [blank_start]shields[blank_end] which prevent heat build-up and allow them to re-enter the atmosphere without burning up.- Ameteors

4When an object is raised vertically, work is done against the force of gravity, and the object gains kinetic energy.

- A10 N/kg
- B50 N/kg
- C50 Hz
- D5 N/kg

8Momentum is a vector.

9The rule of [blank_start]conservation[blank_end] of [blank_start]momentum[blank_end] states that the [blank_start]total[blank_end] momentum [blank_start]before[blank_end] an event is [blank_start]equal[blank_end] to the momentum [blank_start]after[blank_end] an event.

- Bmomentum

- Dbefore

10A [blank_start]force[blank_end] causes a change in [blank_start]momentum[blank_end]. A larger [blank_start]force[blank_end] means a larger change in [blank_start]momentum[blank_end] (and so a greater [blank_start]acceleration[blank_end]). Similarly, if someone's [blank_start]momentum[blank_end] changes very quickly, the [blank_start]forces[blank_end] on the body will be large, and more likely to cause injury.

12Fill in the blanks to complete the passage about regenerative brakes.
Regenerative brakes are used in some [blank_start]electric[blank_end] or hybrid cars. They use the system that drives the vehicle to do the majority of the braking. Rather than converting [blank_start]kinetic[blank_end] energy into [blank_start]heat[blank_end] energy, they [blank_start]put the vehicle's motor into reverse[blank_end]. With the motor running backwards, the wheels are [blank_start]slowed[blank_end].
This also allows the motor to act as [blank_start]an electric generator[blank_end], converting [blank_start]kinetic[blank_end] energy into [blank_start]electrical[blank_end] energy, which is subsequently converted into [blank_start]chemical[blank_end] energy and stored in the vehicle's [blank_start]battery[blank_end]. This makes regenerative brakes far more efficient.- Aelectric

13Complete the passage about safety in a car.
[blank_start]CRUMPLE ZONES[blank_end] - Located at the [blank_start]front and back[blank_end] of the car, these [blank_start]crumple[blank_end] on impact. This means that the car's kinetic energy is converted into [blank_start]other forms of[blank_end] energy by the car body as it changes [blank_start]shape[blank_end]. Also [blank_start]crumple zones[blank_end] [blank_start]increase[blank_end] the impact time, [blank_start]decreasing[blank_end] the force produced by the change in [blank_start]momentum[blank_end].
[blank_start]SIDE IMPACT BARS[blank_end] - These are strong [blank_start]metal[blank_end] tubes fitted into car [blank_start]door panels[blank_end]. They help direct kinetic energy away from the passengers to other areas of the car, such as [blank_start]the crumple zones[blank_end].
[blank_start]SEAT BELTS[blank_end] - These [blank_start]stretch[blank_end] slightly, which increases the [blank_start]time taken[blank_end] for the wearer to stop. This decreases the [blank_start]forces[blank_end] that hit the individual's [blank_start]chest[blank_end]. Some of the kinetic energy is also [blank_start]absorbed[blank_end] by the seat belt stretching
[blank_start]AIR BAGS[blank_end] - These also [blank_start]slow you down[blank_end] more gradually and prevent you from hitting [blank_start]hard surfaces[blank_end] inside the car..- ACRUMPLE ZONES
