Forces and motion - movement and position Flashcards
Be able to plot a distance time graph
- Draw/label the horizontal axis for the time and a vertical axis for the distance.
- Use the information about the distance or speed of the object to plot points on the graph.
- Join the points with straight line segments.
What does it mean in a distance-time graph when the line is flat (parallel to the x-axis)
That the thing is stationary

What does it mean in a distance-time graph when the line is straight and diagonal left to right going up and when going down
going up - moving away at a constant speed
going down - moving close at a constant speed

What does it mean in a distance-time graph when the line is curved upwards and downwards
Upwards - accelerating
Downwards - Decelerating

How to work out the speed in a distance time graph

Practical: Investigate the motion of everyday objects such as toy cars or tennis balls
Know and use the relationship between change in velocity, time taken and acceleration
change in velocity
acceleration= —————————
time taken
v-u
a = ——-
t
plot and explain velocity-time graphs

Calculate the acceleration of a line from a graph
(use equation on graph use graph to try and figure it out + doesn’t explain on the link) https://www.bbc.co.uk/bitesize/guides/z3whb82/revision/4
