Fill in the blanks to complete the passage.

When and enter the atmosphere, they have a very energy. Due to with particles in the atmosphere, some of the energy is transferred to energy, and is . The temperatures become so that most burn up; but have heat which prevent heat build-up and allow them to re-enter the atmosphere without burning up.

Fill in the blanks to complete the passage about regenerative brakes.

Regenerative brakes are used in some ( electric, petroleum, diesel, biofuel, autonomous ) or hybrid cars. They use the system that drives the vehicle to do the majority of the braking. Rather than converting ( kinetic, electrical, heat, sound, gravitational potential ) energy into ( heat, kinetic, sound, gravitational potential, electrical ) energy, they ( put the vehicle's motor into reverse, stop the vehicle's motor instantly, reduce friction between the tyres, recharge the motor during the braking ). With the motor running backwards, the wheels are ( slowed, sped up, stopped, not damaged ).

This also allows the motor to act as ( an electric generator, a battery, a motor, a power supply ), converting ( kinetic, heat, sound, electrical, chemical ) energy into ( electrical, heat, sound, kinetic, chemical ) energy, which is subsequently converted into ( chemical, electrical, kinetic, heat, sound ) energy and stored in the vehicle's ( battery, motor, brakes, power supply ). This makes regenerative brakes far more efficient.

Complete the passage about safety in a car.

- Located at the of the car, these on impact. This means that the car's kinetic energy is converted into energy by the car body as it changes . Also the impact time, the force produced by the change in .
- These are strong tubes fitted into car . They help direct kinetic energy away from the passengers to other areas of the car, such as .
- These slightly, which increases the for the wearer to stop. This decreases the that hit the individual's . Some of the kinetic energy is also by the seat belt stretching
- These also more gradually and prevent you from hitting inside the car..
