**Speed**is the motion of the object and how fast it moves, calculated by distance over time.

**Distance**- the amount of space between two points.

A

**displacement**of an object with respect to an initial point is define as the vector distance from the initial point to the final point; how far something is from the start until where it has travelled.

**Total distance**traveled, the distance traveled during the journey of an object.

**Time**, The duration for the whole journey, how long it does.

**Velocity**, the acceleration of the motion of the object. Average speed, the distance traveled/ total time traveled.

**Acceleration**, the increase in speed over time.

**Deceleration**, the decrease in speed over a period of time.

2. Formulae (relationship)

speed = distance / time

3. Key learning points from motion detector

I) I have learnt that the actual accuracy could not be that accurate and straight, as we have expected

II) I have learnt that velocity has something to do with motion

III) I have learnt that the velocity changes only when there is motion.

WELL DONE ! your group is able to capture the key essence of the topics.

ReplyDeleteSuggestion for improvement:

Formulae to include:

Acceleration = velocity / time

Average speed

total distance travelled
