Uniform and non-uniform acceleration

Uniform and non-uniform motion

Uniform and variable velocity

What do you understand by displacement-time graph? Draw a displacement-time graph for a girl going to school with uniform velocity. How can we calculate uniform velocity from it?

What is velocity-time graph? Sate how it can be used to find:

i. acceleration of a body

ii. the displacement of a body, and

iii. the distance travelled in a given time
