Scientific Method: 4 And 5 Are Combined)
Chapter 1
Scientific Method: (4 & 5 are combined)
1. Observe Closely observe the physical world around you.
2. Question Recognize a question or a problem.
3. Hypothesize Make an educated guess—a hypothesis—to answer the question. Must be able to be proven rright or wrong(false or true).
4. Predict Predict consequences that can be observed if the hypothesis is correct.
The consequences should be absent if the hypothesis is not correct.
5. Test predictions Do experiments to see if the consequences you predicted are present.
6. Draw a conclusion Formulate the simplest general rule that organizes the hypothesis, predicted effects, and experimental findings.
But scientifically speaking, a theory is a synthesis of facts and welltested …show more content…
3. Objects under the influence of very strong gravitational forces. To understand the motions of such astronomical objects, we invoke Einstein’s theory of general relativity, which appears valid for all gravitational forces.
Summary of Terms
Free fall Motion under the influence of gravitational pull only.
Force vector An arrow drawn to scale so that its length represents the magnitude of a force and its direction represents the direction of the force.
Interaction Mutual action between objects in which each one exerts an equal and opposite force on the other.
Newton’s first law of motion Every object continues in a state of rest, or in a state of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted on it.
Newton’s second law of motion The acceleration produced by a net force on an object is directly proportional to the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object.
Newton’s third law of motion Whenever one object exerts a force on a second object, the second object exerts an equal and opposite
