Equation for Speed
Speed = Distance/Time
Equation for Time
Time = Distance/Speed
Equation for Distance
Distance = Speed x Time
Standard Unit for Distance
Metres (M)
Standard Unit for Speed
Metres per Second (m/s)
Standard Unit for Time
Seconds (s)
What is the slope of a graph called
Gradient - You calculate the speed of an object from this
What does is mean if the line is steeper in a Distance - Time graph
Faster the speed
What does Distance and Graph show
Shows how fast or slow an object is moving, but it can also tell us which direction an object is moving
What axis is Time
X
What axis is Distance
Y
If an object is moving in a steady speed what will distance and time graph show
A straight line
If it’s speed is changing and the object is accelerating what will Distance and Time graph show
The line of the graph will be curved
