- 1What common words are used when describing motion?Distance, Time, Speed, and Position
- 2What is magnitude?The size of measurement or the amount you are counting.
- 3What are scalar quantities?Quantities that show magnitude but not direction.
- 4What are vector quantities?Quantities that show magnitude and direction.
- 5What is the difference between distance and position?Distance in a scalar quantity (d) that describes the lengths of paths between two points or locations.
Position is a vector quantity (d ->) that describes a specific point relative to a reference point. - 6What is time?A scalar quantity that describes when an event occurs.
- 7How do you calculate a time interval?Difference in time equals time final take away time initial
∆t = t(f) − t(i) - 8What is displacement?A vector quantity that describes the straight line difference and direction from one point to another.
- 9How do you calculate displacement?Displacement equals position final take away position initial.
∆d = d -> (f) - d -> (i) - 10What is uniform motion?Objects in uniform motion travel equal displacements in equal time intervals.
- 11How is uniform motion graphed?an upwards angled straight line.
- 12What is a line slanting up to the right? A) Positive slope B) Zero slope C) Negative slopeA
- 13What is a line going horizontally? A) Positive slope B) Zero slope C) Negative slopeB
- 14What is a line that slants down to the right? A) Positive slope B) Zero slope C) Negative slopeC
- 15What is speed?Speed (v) is a scalar quantity that measures the distance an object travels during a certain time interval divided by the time interval.
- 16What is velocity?Velocity is a vector quantity describing the displacement of an object during a time interval divided by the time interval.
- 17Slope is represented by what?Rise/run
slope =∆d
∆t - 18What is average velocity?Average velocity (Vav ->) is the rate of change in position for a time interval.
- 19What does a zero slope mean about average velocity?It means the object was not in motion.
- 20How do you calculate average velocity?Average velocity equals displacement over time
v av = ∆d ->
∆t - 21How do you calculate displacement?Displacement equals velocity average times time
∆d = (V av )(∆t) - 22How do you calculate time?Time equals displacement over velocity average.
∆t = ∆d
v av - 23What is a change in velocity?When the speed of an object changes and/or the direction of motion changes.
- 24How do you calculate change in velocity?a change in velocity equals velocity final take away velocity initial.
∆v = v (f) − v (i) - 25What is acceleration?The rate in change of velocity.
- 26How do you calculate acceloration?Acceleration equals change in velocity over change in time.
a =∆v
∆t - 27What is the acceleration due to gravity?9.8 m/s2 downwards.
