Key learning points

1. Vectors are parallel if the gradient of each vector is the same.
2. If drawn, you can see this visually.
3. Parallel vectors are multiples of each other.

Keywords

• Parallel - Two lines are parallel if they are straight lines that are always the same (non-zero) distance apart.

• Gradient - The gradient is a measure of how steep a line is. It is calculated by finding the rate of change in the y-direction with respect to the positive x-direction.

• Displacement - Displacement is the distance from the starting point when measured in a straight line.
