Lesson details
Key learning points
- The velocity of an object is its speed in a given direction.
- The displacement of an object is the distance it travels in a particular direction.
- Displacement and velocity are both vector quantities.
- Velocity has a positive value in one direction and negative value in the opposite direction.
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.
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.
