Упр.8 Is physics difficult? ГДЗ Enjoy English 11 класс

Work in pairs. Describe what’s going on in the picture below. Say what forces are acting on the object (the sledge).

The sledge is moving down the hill. The force of gravity is acting on it and pulling it downward. There is also friction between the sledge and the snow, which slows it down. If the sledge is being pulled by a person or an animal, then the pulling force is acting too.
