Science Unit 1: Flight Chapter 1 Test Material

Weight is a force that pulls the plane down towards the ground. It is related to flying machines as they need to generate enough lift to overcome the force of weight and become airborne.

The impact of flying machines at a local level includes air pollution, noise pollution, and habitat disruption due to the space requirements of airports.

Biodiversity means that there are many types of living things. It is related to agriculture as it involves growing diverse plants, fungi, and raising farm animals to maintain a healthy ecosystem.
