  1. Can you get a straw all the way through a potato?

  2. Extended Learning Task Write this down in your planner: By Friday, look at BBC Bitesize (AQA Additional Science). Read the ‘revision’ section on Representing Motion. Complete the ‘activity’. Extended Learning Task

  3. Tuesday, 13 September 2011 Motion • Learning Objectives: • How to interpret the slope of a distance-time graph. • How to calculate the speed of a body using the speed equation. • The difference between speed and velocity.

  4. How do the rozzers know when to give you a speeding ticket? http://www.bbc.co.uk/learningzone/clips/calculating-the-speed-of-a-car/23.html

  5. Copy this page The equation to remember: Speed = Distance Time The units we use for speed (in physics) are m/s (metres per second) Speed - Time Graphs http://www.bbc.co.uk/learningzone/clips/speed-time-graphs/10673.html

  6. Copy this page The Voyager 1 is travelling at 17 500 m/s and has been travelling for around 30 years. How far away is it now?

  7. Copy this page How to answer physics questions Write out the equation you use Distance [m] = Speed [m/s] x Time [s] Write in the numbers of what you know Distance = 17 500 [m/s] x (30 x 365 x 24 x 60 x 60) [s] Calculate the answer and remember the units Distance = 1.66 x 1013 m (16 600 000 000 000 m!)

  8. Copy this page Distance (metres) Time (seconds) Distance – Time Graphs We can represent the motion of an object on a distance – time graph. The gradient of the line shows us the speed of the object. Steep line = fast. Shallow line = slow.

  9. Tuesday, 13 September 2011 Velocity and Acceleration • Learning Objectives: • Define acceleration as the rate of change of velocity. • Interpret the slope of a velocity-time graph. • Calculate the distance travelled by the area under a v-t graph.

  10. Velocity is speed in a given direction.

  11. Acceleration is the rate of change of velocity. • The slope of a velocity-time graph allows you to work out the acceleration. a = v – u t

  12. a = v – u t Acceleration from a graph v Velocity u t time

  13. Task 1 – you try v = 12 Velocity u = 4 time t = 16 u = 15 Velocity v = 5 t = 10 time

  14. Count/calculate the number of tiny squares in each shape.

  15. The distance travelled is the area under a velocity-time graph. v Velocity u t time

  16. Extended Learning Task Draw an accurate and detailed distance-time and a velocity-time graph for a journey that someone else in your family makes. Interview them to get the data you need. Label the graphs to explain what they are doing at each stage on the graphs. Extended Learning Task

  17. Draw a distance-time graph, a velocity-time graph and work out the distance travelled for the following scenario. A ferret travels: • 4 metres in 10 seconds, • then it is stationary for 5 seconds, • then 2m in 2s, • then 8m in 1s, • then 1m in 8s, • then 3m in 6s.

  18. If the velocity is increasing then acceleration is a positive value. • When we have a negative acceleration (a deceleration) then the velocity is decreasing. • If the acceleration is 0 then an object is either stationary, or travelling at a constant velocity.

  19. Copy this table Velocity Acceleration Distance

  20. The Matrix Car Chase

  21. Plot these results on a speed time graph, with time on the bottom axis (the x axis) and speed on the side axis (the y axis). Label the points where there is a change in motion A,B,C,D,E,F,H,I,J and K. For example: point A is at time 0 and speed 0.
