|
What does it mean when the line is steeper? |
The steeper the line, the greater the speed it represents |
|
|
What does a distance time graph show? |
It shows the distance of an object from a starting point (y axis) against time taken (x axis) |
|
|
What is the SI unit of distance? |
Distance traveled in meters, m |
|
|
If an object is stationary.... |
The line on a distance-time graph is horizontal |
|
|
What is velocity? |
The velocity of an object is its speed in a certain direction. If the object changes direction it changes velocity even if the speen stays the same. |
|
|
What is is called when the velocity of an object changes? |
Acceleration |
|
|
Calculation for acceleration? |
a= v-u ______ T |
|
|
In the equation for acceleration what do the letters stand for? |
a is the acceleration in meters per second squared m/s2 V is the final velocity in meters per second m/s U is the initial velocity in m/s T is the time taken for the change in seconds s |
|
|
What does a velocity time graph show? |
It shows the velocity of an object (y axis) against time taken (x axis) |
|
|
What does the gradient of a line represent on a velocity-time graph? |
Acceleration |
|
|
If the line on a velocity-time graphis horizontal then what does it mean? |
That the acceleration is zero. Therefore the object is traveling at a steady speed. |
|
|
How can an object traveling at a steady speed be accelerating? |
By changing direction |
