# Energy in Remote-Controlled Cars **Activity 2** **Look at the opposite pictures, then put (√) or (X):** 1. The child in picture (1) uses a remote control to move the car. **(√)** 2. The child in picture (2) can move the car remotely. **(√)** 3. Both cars in the opposite pictures need electric energy to move. **(√)** **Energy in Remote-Controlled Cars:** * Many toys such as cars, trucks, planes, boats, and small robots can operate remotely. * However, all of these toys need energy to move and perform activities, like spinning in the corners and moving forward or backward. **How do those toys get energy?** Batteries inside the toys are a source of chemical energy, which is converted into electrical energy. Electrical energy is converted into kinetic energy or sound energy to move the toys and make them perform their activity. **But, What do we do when the batteries run out?** Batteries can be recharged by connecting the device to a nearby charger, or by replacing the old batteries with new ones. **Check your understanding:** **Complete the following sentences using the words below:** (kinetic - chemical - electrical) 1. The energy stored in batteries is **chemical** energy. 2. In batteries of a remote-controlled toy, **chemical** energy is converted into **electrical** energy, which is converted into **kinetic** energy or sound energy. **Vocabulary:** | Arabic Term | English Term | |---|---| | جهاز تحكم | remote control | | إنسان آلى | robots | | طاقة كهربية | electrical energy | | شاحنات | trucks | | الطاقة الصوتية | sound energy | | أن يؤدي | perform | | الطاقة الحركية | kinetic energy | | طاقة كيميائية | chemical energy | | بطاريات | batteries | | مصدر | resource | | إعادة شحن | recharge | | نفذ | run out | **Note:** Some terms were translated based on likely meanings, as they were not perfectly clear.
