When analyzing data over time, one of the best graphical depictions of data is the line graph. A line graph often uses time as its x-axis and a numerical quantity on its y-axis.

If the velocity-time graph is curved, the acceleration can be found by calculating the gradient of a tangent to the curve. Example The velocity of a sledge as it slides down a hill is shown in the ...

Teaching children about money can be a fun and rewarding experience. By introducing them to the concept of compound interest, you can set the foundation for a lifetime of smart financial decisions.

If we have a speed-time or velocity-time graph, the distance travelled can be estimated by finding the area. Example The velocity of a sledge as it slides down a hill is shown in the graph.
