DISTANCE-TIME GRAPHS
- On a graph, the gradient equals the speed that the object is travelling
- The flat sections show when it has stopped
- Curves represent acceleration or deceleration
- Downhill sections represent when the object has changed direction and is coming back to the starting point
SPEED-TIME GRAPHS
- On a graph, the gradient equals the acceleration
- The flat sections represent steady speed
- The steeper the gradient, the greater the acceleration
- The area under any section on the graph represents the distance travelled
ACCELERATION --> How quickly the speed is changing
SPEED --> How fast an object is travelling (direction is not important)
VELOCITY --> The speed of something in a given direction
RELATIVE VELOCITY --> If two objects are moving parallel, the relative velocity is the difference in their velocities (they could be moving in the same direction or a different direction, as long as they are parallel)
TERMINAL VELOCITY --> When an object firsts starts moving, it has much more force accelerating…
