Distance-time graphs ... find the average of the speeds for sections A, B and C. The gradient in section E is -8. The speed is 8 miles per hour because speed is always a positive value. The ...

Acceleration (a)- the rate of change of an object’s velocity over time. Displacement (s)- the total distance ... find out the solution. The first equation can be derived using a velocity-time ...

They are afraid to embrace the power of the graph ... way to find the acceleration from this distance-time data. Let's go back to our kinematic equation (assuming we start with zero velocity).

\(gradient = \frac{change~in~y}{change~in~x} = \frac{change~in~distance}{change~in~time} = \frac{change~in~metres}{change~in~seconds} = m/s.\) The gradient of a ...
