AQA P2.1 (Time graphs etc)

Heres a slide show about the graphs and distance-time and velocity- time etc etc

Trouble is the higher tier is pretty hard to show on a powerpoint :P so don't use this for ALL ur revision, ain't enough there ahaha (i wish there was lool)

Good Luck **

Here's a taster:

Distance-time graphs
We use distance-time graphs to help us show the
motion of a object (body)
The Y axis shows the distance between the
object and the start
The X axis shows the time taken…read more

Here's a taster:

The slope on the graph shows the speed, the
steeper the gradient the greater the speed
We can calculate the speed of the body by using
the equation:
Speed = distance / time
The unit is m/s D
SxT…read more

Here's a taster:

Velocity and acceleration
The velocity of a body is its speed in a given
direction.
If the body changes direction its velocity will
change
When the velocity changes, we say it accelerates…read more

Here's a taster:

To calculate acceleration, the equation is:
Acceleration = Change in velocity
time taken for change
The unit for this is m/s²
If the answer to the equation is negative, the
object decelerating (slowing) down…read more
