3.04 Summary
- Displacement time graphs
- The gradient of the graph represents the velocity of the object
- An object moving with constant velocity produces a straight line graph
- The steeper the gradient the greater the velocity
- The shallower the gradient the lower the velocity
- An object whose velocity is changing produces a curved graph
- If the velocity is increasing the gradient of the graph gets steeper
- If the velocity is decreasing the gradient get shallower
- Velocity time graphs
- The gradient of the graph represents the acceleration of the object
- An object moving with constant acceleration produces a straight line graph
- The steeper the gradient the greater the acceleration
- The shallower the gradient the lower the acceleration
- If the value of acceleration is different for different sections of the objects motion this produces a graph with a different gradient for each section
- An object whose acceleration is changing produces a curved graph
- If the acceleration is increasing the gradient of the graph gets steeper
- If the acceleration is decreasing the gradient get shallower
- The area under a velocity time graph represents the change in displacement caused by the objects motion
