Distance Time Graphs and Probability Unit 11A and C Distance Time Graphs and Probability

Motion Any object changes position over time when compared to a reference point

Reference Point Gives location at a specific point which does not move

Object at Rest An object that does not change its position

Distance How far an object travels

Displacement How far an object travels from its starting point

Speed Distance traveled in a given amount of time; velocity

Outcome The result of a single trial of an experiment

Experiment A situation involving chance that leads to results, or outcomes

Sample Space A list of all possible outcomes of an experiment

Event Outcome for a given situation; trial

Simple Event An event consisting of one outcome

Probability A measure of the likelihood that an event will occur; often written as P(event)

Equally Likely When the probabilities of all the outcomes of an experiment are equal

Experimental Probability The ratio of the number of times an event occurs to the total number of trials performed

Theoretical Probability The mathematical calculation that an event will happen in theory

Tree Diagram A tree-shaped diagram that illustrates the possible outcomes of a given situation

Compound Event Combines two or more events using the word “and” or the word “or”

Replacement Occurs during compound events in which an object is returned to the possible outcomes pool after being selected
