Question | Answer |
what is the definition of pendulum | a mass hung from a fixed point, free to swing back and forth when put in motion |
what is the definition of cycle | any motion or activity that repeats its self |
what is the definition of varible | a factor or condition that can change and might effect the out come of an experiment |
what is the definition of standard | the basic procedure used in a controlled experiment, before changing any of the varibles |
what is the definition of controlled experiment | an experiment in which one and only one, varible is changed ib order to asses or judge its effect |
Answer this key question: which varibles made no effect in the number of swings of a pendulum | 1. Weight of bob 2.Height of drop |
Answer this key question: what varible did make an effect | the length of the string |
Answer this key question:is there a relationship between the length of a pendulum and the number of swings it makes in a unit of time | yes, it does |
what is the definitintion of capacity | the maximum volume of fluid a container can hold |
why does a heavy log float in water | because wood is less dense |
how can you tell which items will float | less density= will float greater density= will sink same density= newtral |
What is the definition of a two coordinate grid | Shows the out come of a series of experiments and compared to standard |
Who was Galileo | An Italian astronomer who thought the pendulum to keep time |
What is the definition of density | The amount of matter that will fit in a given space |
Who was Archimedes | The person who showed water displacement could tell more about an object |
Identify variables that affect the number of passengers lifeboats can hold | 1.penny placement 2.shaking water 3.wet pennies 4.wet boat |
Describe the relationship between the capacity of a boat and the number of passengers it can hold | A bigger ship= more passengers it can hold
A smaller ship= lesser passengers it can hold |
