Class 9 Science | The Velocity Time Graph

Science and Technology, Class 9, Unit 7

The Velocity Time Graph

Time on the x-axis · Velocity on the y-axis · Slope gives acceleration

Today's Goals

📊

Draw a velocity time graph from data

📐

Find acceleration from the slope of the line

〰️

Tell uniform from non-uniform acceleration by shape

🔽

Spot the piece where the body slows down

📏Displacement time graph

Slope gives velocity

Flat line means at rest

Curve means non-uniform speed

🚀Velocity time graph

Slope gives acceleration

Flat line means uniform velocity

Curve means non-uniform acceleration

Presenter notes: Today we learn to read the graph of motion. By the end, one look at a line will tell us how the body is moving.
