Flashcards do conjunto (19)
- 1When is an object in motion?An object is in motion when it changes position relative to a reference point
- 2Reference pointa place or object used for comparison to determine if something is in motion
- 3Relative motionwhen you're in any reference point which is moving at a constant speed within the earth
- 4International System of Unitsthe length of the path between two points
- 5How do you calculate speed?divide the distance the object traveled by the total time it takes to travel that distance
- 6How do you describe velocity?the speed and direction of an object's motion
- 7How do you graph motion?on a line graph where you plot distance vs time
- 8Speedthe distance an object moves per unit of time
- 9Average speedthe speed of an object over a longer period of time
- 10Instantaneous speedthe speed at which an object is moving at a given instant in time
- 11Velocityspeed in a given direction
- 12Slopethe steepness of a line on a graph
slope = rise/run - 13What is acceleration?refers to increasing speed, decreasing speed, and changing direction
- 14How do you graph acceleration?use either a speed vs time and a distance vs time graph to analyse the motion of an accelerating object
- 15How do you calculate acceleration?final speed - initial speed
-------
time - 16Accelerationthe rate at which velocity changes
- 17Decelerationwhen an object slows down its speed
- 18Changing speedwhen an object changes its speed
- 19Changing directionacceleration can be a change in direction
