Motion
- Distance Time Graphs
- The gradient of the line on a distance-time
graph represents the objects speed
- The steeper the line on a distance-time
graph the greater the speed it represents
- Speed (m/s) = Distance travelled (m)
/ Time taken (s)
- The gradient of the line on a distance-time
graph represents the objects speed
- Velocity And Acceleration
- Velocity is speed in a given
direction
- Acceleration is the change of
velocity per second
- a = v - u
t
- Velocity is speed in a given
direction
- Velocity-Time Graphys
- If the line on a velocity-time
graph is horizontal, the
acceleration is zero
- The gradient of a velocity-time
graph represents acceleration
- The are under the line on a
velocity is the distance travelled
- If the line on a velocity-time
graph is horizontal, the
acceleration is zero
- Using Graphs
- The speed of an object is
given by the gradient of the
line on its distance-time
graph
- The acceleration of an object is
given by the gradient of the line on
its velocity-time graph
- The distance travelled by an object is given
by the area under the tine of its velocity-time
graph.
- The speed of an object is
given by the gradient of the
line on its distance-time
graph
