Doc Brown's GCSE OCR 21st Century Science-Physics Revision Notes

PLEASE NOTE NEW revision summaries for the NEW OCR 21st Century Science B GCSE Physics B and NEW OCR GCSE 21st Century Combined Science B Physics courses: Revision for Chapters P1-3 and  Chapters P4-6 STARTING with Y10 in Sept. 2016 onwards, first exams in 2018

OCR GCSE 21st Century Science Physics Module P4 Explaining motion

P4.1 How can we describe motion?

 

 

  • 1. be apply the following equation to situations where an average speed is involved:

    • speed (m/s) = distance travelled (m) / time taken (s)

    • s = d/t

  • 2. Be able to distinguish between average speed and instantaneous speed (in effect, an average over a short time interval) for examples of motion where speed is changing

  • 3. HT only: understand that the displacement of an object at a given moment is its net distance from its starting point together with an indication of direction

  • 4. Be able to draw and interpret a distance-time (or displacement-time) graph for an object that is:

    • a) stationary

    • b) moving at constant speed

    • c) HT only: moving with increasing or decreasing speed

  • 5. Be able to interpret a steeper gradient of a distance-time graph as a higher speed

  • 6. HT only: Be able to calculate a speed from the gradient of a straight section of a distance-time graph

  • 7. Be able to draw and interpret a speed-time graph for an object that is:

    • a) stationary

    • b) moving in a straight line with constant speed

    • c) moving in a straight line with steadily increasing or decreasing speed (but no change of direction)

  • 8. understand that in many everyday situations, acceleration is used to mean the change in speed of an object in a given time interval

  • 9. know that the instantaneous velocity of an object is its instantaneous speed together with an indication of the direction

  • 10. HT only: understand that the velocity of an object moving in a straight line is positive if it is moving in one direction and negative if it is moving in the opposite direction

  • 11. HT only: Be able to draw and interpret a velocity-time graph for an object that is:

    • a) stationary

    • b) moving in a straight line with constant speed

    • c) moving in a straight line with steadily increasing or decreasing speed (including situations involving a change of direction).

  • 12. HT only: Be able to calculate the acceleration from the gradient of a velocity–time graph (or from a speed- time graph in situations where direction of motion is constant)

  • 13. Be able to calculate acceleration using the equation:

    • acceleration (m/s2) = change in velocity (m/s) / time taken (s)
