Physics 2a - Motion, Energy and Electricity (Velocity and time distance graphs)
Cards in this deck (8)
- 1What is speed?How fast you are travelling with no regard to direction.
(30 mph or 20 m/s etc) - 2What is velocity?Velocity is the same as speed but with the direction specified.
(30 mph north, 20 m/s 060°, etc) - 3How to you work out the speed from this time-distance graph?Gradient = speed so you divide the vertical by the horizontal. For example, between 300 meters and 20 seconds, you would do 300/20 which makes 15 m/s.
- 4What do the flat sections mean on these distance-time graphs?The straight lines mean that the object is stationary - not moving.
- 5How does the steepness of the gradient relate to the speed of the object moving.The steeper the gradient, the faster the object is travelling.
- 6What do the curves represent?Acceleration/deceleration depending on direction of curve.
- 7Explain what each curve means - steepening and levelling?Steepening means that the object is accelerating faster and faster.
Levelling means that the object is decelerating slower and slower.
- 8What do the straight lines mean going up or down?The straight lines mean that the object is travelling at a steady speed. Going up means it is going away from the start point and going down means it is coming back to the start point.
