.speed describes how quickly something is moving

What are the units of speed?

.scientists measure speed using the units METRES PER SECOND m/s or ms-1 (little 1)

what are some other units speed?

.kilometres per hour Km/h .Miles per hour Mph

what is the calculation used to measure speed?

. speed= distance (divided by) time

What is a distance time graph ?

.A distance time graph is a scatter plot graphs that plots time on the x-axis and distance on the y-axis.

what are the steps for drawing a scatter plot?

1.Leave space at the bottom and left hand side of your page to label your axes (one red box) 2. Draw your x and y axes- independent variable (one you changed ) on the x axes 3. label the axes, include units (cm,kg, etc).

what are the other steps for drawing a scatter plot?

4. scale the x-axis - is there enough space? 5. scale the y-axis is there enough space? 6.add increments (dashes) to both axes 7.plot the data-find correct position on graph mark with dot/x

what are the remaining steps for drawing a scatter plot?

8.add trend line A. a straight line with a ruler if the points are in a row B. a freehand curve if the points are not in a row (. Give the graph a title-what is it showing?

what dose the term as the crow flies mean?

.This expression means the distance between two locations, regardless of roads or paths

What is displacement?

.displacement is the distance in a given direction .distance+direction .distance between start and finish points

.distance is the length of the path followed

how do you lay out a sum of displacement?

for displacement, you need to give a figure for distance AND the direction of travel for example 100m east

.units used are the same as speed, but the direction has to be indicated also .metres per second (m/s)

.what is the formula doe velocity ?

velocity=change in displacement(divided by) time taken

What is acceleration?

.the acceleration of an object is the change in velocity in one second .units are metres per second squared m/s2 (little 2)
