## Lesson details

### Key learning points

- Velocity of an object is its speed in a given direction.
- Displacement is distance in a particular direction.
- Displacement and velocity are vectors.
- Velocity is positive in one direction and negative in the opposite direction.
- Movement around a circle at a steady speed involves a changing velocity.

### Common misconception

Pupils often have a tendency to believe that a velocity must have a positive value and have difficulty in associating a reverse in direction with a change in sign.

It is important to make sure pupils are secure in their knowledge of the vector–scalar distinction; use plenty of visual examples.

### Keywords

Displacement - The displacement of an object is the distance travelled in a particular direction from a starting point.

Vector - A vector is a quantity with magnitude (size) and direction. Displacement and velocity are both vector quantities.

Velocity - The velocity of an object is its speed in a particular direction.
