Distance VS Time

Interpret The Graph Below:

Time


Time is increasing,

and distance

is increasing

constantly with

time.

The runner moves

at a constant

speed. The straight

line shows that it is

constant speed.

Constant Speed (steady)

Dis

tance

The runner is traveling at constant speed towards the finish line.

(m)


Just like the

previous graph,

this graph

shows the

runner moving

with constant

speed.

Constant Speed (steady)

The runner is traveling back to the start line.

Time is increasing,

but the distance

does not change.

The runner is not

moving.

We say it is At Rest.

No Movement – Flat line The runner is waiting for the baton to be passed to them.

Dis

tance (

m)

The curve in the

graph shows

that the runner’s

speed is

changing as time

passes.

Increasing Speed (Acceleration)


The runner starts jogging at a constant speed, it starts raining and

they decide to sprint (run fast) home.


Let’s look at two

runners:

Both of the lines on

the graph show that

each runner moved

about the same

distance, but the

steeper dashed line

got there before the

solid line:

A B

Dis

tance (

m)

Time (s)

A steeper line indicates

a larger distance

moved in a given time.

In other words, faster

speed.

Both lines are straight,

so both speeds are

constant.


Runner A is the faster runner.

Runner’s speed starts out extremely fast, and eventually

decreases their speed to no motion at all.

Interpret The Graph Below: In the first part of the

graph the object is

moving with constant

speed.

In the second part of

the graph the object is

at rest (not moving).

In the third part the

object is again moving

with constant speed.

Runner is running fast at constant speed, takes a break, then jogs

home at a constant speed.

Speed VS Time AKA : Velocity-Time graphs.

Interpret The Graph Below: Speed-Time graphs

look much like

Distance-Time graphs.

Be sure to read the

labels!!

Time is plotted on the

X-axis. Speed or

velocity is plotted on

the Y-axis.

A straight horizontal line on a speed-time

graph means that speed is constant.

DOES NOT MEAN “AT REST.”

In the race, the dashed line shows a greater

acceleration and would be ahead of B.

Both the dashed and

solid line show

increasing speed.

Both lines reach the

same top speed, but

the solid one takes

longer.
