What is the definition of SCIENCE?

• The observations, measurements, and other types of data that people gather and test to support and evaluate scientific explanations.

• The systemic study of the natural world.

• An organized procedure to study something under controlled conditions.

• A condition or factor that is assumed to have one value, or remain unchanged, throughout a particular investigation.

What is the definition of VARIABLE?

• A condition or factor that is assumed to have one value, or remain unchanged, throughout a particular investigation.

• A testable idea or explanation that leads to scientific investigation.

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

• Any factor that can change in an experiment, observation, or model.

What is the definition of GRAPH?

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

• The process of obtaining information by using the senses; the information obtained by using the senses.

• A visual representation of data.

• Information gathered by observation or experimentation that can be used in calculating or reasoning.

What is the definition of MODEL?

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

• A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept.

• An organized procedure to study something under controlled conditions.

• Information gathered by observation or experimentation that can be used in calculating or reasoning.

What is the definition of DEPENDENT VARIABLE?

• In a scientific investigation, the factor that changes as a result of manipulation of one or more independent variables.

• Information gathered by observation or experimentation that can be used in calculating or reasoning.

• A test model of a product.

• The application of science and mathematics to solve real-life problems.

What is the definition of ENGINEERING?

• The application of science and mathematics to solve real-life problems.

• The study of the characteristics and uses of materials in science and technology.

• Information gathered by observation or experimentation that can be used in calculating or reasoning.

• Any factor that can change in an experiment, observation, or model.

What is the definition of FORCE?

• A push or a pull exerted on an object.

• Friction-like force that opposes motion of an object in the air or liquid

• The force that resists the start of sliding motion.

• The tendency of an object to resist change in motion.

What is the definition of NET FORCE?

• Forces on an object that produce a net force of 0 N(newtons) – there is no motion.

• Friction-like force that opposes motion of an object in the air or liquid

• The combination of all of the forces acting on an object.

• Forces on an object that do not produce a force of 0 N(newtons) – there is motion.

What is Newton's THIRD LAW OF MOTION?

• The acceleration of an object depends on the mass of the object and the amount of force being applied.

• An object stays at rest, an object stays in motion, unless an unbalanced force acts upon it.

• For every action, there is an equal and opposite reaction.
