part 1 exam study guide

Newton’s first law of motion

• Fnet = mass x acceleration

• (law of inertia) an object will retain its state of motion unless acted upon by a net force

• forces that are equal” this result in constant velocity or sitting still

• for every action force there is an equal and opposite reaction force 

Newton’s second law of motion

• for every action force there is an equal and opposite reaction force 

•  (law of inertia) an object will retain its state of motion unless acted upon by a net force

• Fnet = mass x acceleration 

• forces that are not equal; there is some net force: acceleration is produced

Newton’s third law of motion

• (law of inertia) an object will retain its state of motion unless acted upon by a net force

•  Fnet = mass x acceleration 

• for every action force there is an equal and opposite reaction force 

• the force of gravity on an object 

Balanced forces

• Balanced forces occur when there is no force acting on an object.
• Balanced forces occur when two forces of equal magnitude act in opposite directions, resulting in a net force of zero.
• Balanced forces occur when two forces act in the same direction.
• Balanced forces occur when two forces of unequal magnitude act in opposite directions.

Weight

• Weight is a measure of the color of an object.
• Weight is a measure of the temperature of an object.
• Weight is a measure of the force of gravity acting on an object.
• Weight is a measure of the speed of an object.

Unbalanced forces

• Unbalanced forces lead to balanced motion.
• Unbalanced forces result in no motion.
• Unbalanced forces cause acceleration. It is forces that are not equal; there is some net force and acceleration is produced

• Unbalanced forces do not affect acceleration.

Mass

• Mass is a measure of the amount of matter in an object.
• Mass is a measure of the speed of an object.
• Mass is a measure of the temperature of an object.
• Mass is a measure of the volume of an object.

Factors that influence gravity

• the force of gravity on an object

• the amount of matter in a substance

• graduated cylinder are always More precise than a beaker

• mass and the distance between the two masses

Conclusion

• state the problem

• form a hypothesis

• experiment

• a decision based upon the data obtained in an experiment

Steps of the scientific method

• Make a prediction, Form a hypothesis, Conduct an experiment, Analyze the data, Draw conclusions, Communicate results
• Observe, Form a hypothesis, Test the hypothesis, Analyze the data, Draw conclusions, Communicate results
• State the problem; form a hypothesis; experiment; Collect data; analyze the data and reach a conclusion

• Ask a question, Form a hypothesis, Conduct an experiment, Analyze the data, Make a conclusion, Share the results
