- Distance Time Graphs
- The gradient of a distance time graph for an object
represents the object's speed
- The steeper the gradient of the line on a graph,
the greater the speed is
- An object moving at a constant speed travels the same
distance every second.
- The steeper the gradient of the line on a graph,
the greater the speed is
- A Stationary object is a horizontal line
- Moving at constant speed is a straight line that slopes upwards
- The gradient of a distance time graph for an object
represents the object's speed
- Velocity
- Velocity is speed in a given
direction
- Acceleration
is CHANGE of
velocity per
second.
- The unit of acceleration is metre per second squared
- Acceleration= change of velocity/ time taken
- Acceleration Equation: a= v-u / t
- v=the final velocity in metres per second
- u=the initial velocity in metres per second
- t= time taken in seconds
- v=the final velocity in metres per second
- Acceleration Equation: a= v-u / t
- The unit of acceleration is metre per second squared
- Velocity is speed in a given
direction
