Chapter 1 Test Prep

What is technology?

• the knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested

• the application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs

• a descriptive statement or equation that reliably predicts events under certain conditions

• a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation

What is a law?

• the knowledge obtained by observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested

• the application of science for practical purposes; the use of tools, machines, materials, and processes to meet human needs

• a descriptive statement or equation that reliably predicts events under certain conditions

What is critical thinking?

• the ability and willingness to assess claims critically and to make judgements on the basis of objective and supported reasons

• a series of steps followed to solve problems, including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions

• a factor that changes in an experiment in order to test a hypothesis

• a measure of the straight-line distance between two points

What is mass?

• a measure of the amount of matter in an object; a fundamental property of an object that is not affected by the forces that act on the object, such as the gravitational force

• a measure of the size of a body or region in three-dimensional space

• a measure of gravitational force exerted on an object; its value can change with the location of the object in the universe

• a method of expressing a quantity as a number multiplied by 10 to the appropriate power
