# Physics forces and motion AQA additional science (Yr9)

I dont know if this is detailed enough for Yr10 above, but it has some good stuff in it, each subtopic is on a different page. Please rate and comment so that I can improve c: Hope it helps!!

MOTION

Scalars and Vectors

A quantity with just a magnitude is a SCALAR

A quantity with magnitude and direction is a VECTOR

SCALA VECTOR

DistanceTime Graphs

Straight is constant velocity

Positive Gradient is travel in one direction

Negative gradient is travel in opposite direction (towards start)

Acceleration is line curving up

Gradient of distancetime graphs

To calculate the gradient of the line on a graph, divide the change in the vertical axis by the

change in the horizontal axis. The gradient of a line on a distancetime graph represents the

speed of the object. Study this distancetime graph.

Velocity m/s
