Do you accelerate for the whole race? I

The max acceleration would be at the start of the race as the sprinter is accelerating from zero. The max velocity would be at the middle of the race

1

Distance

Length of the total path traveled

2

Displacement

Length of the direct line for. Start to finish

3

Speed

Distance travelled per unit time

4

Velocity

Displacement per unit time

5

How to go from km/h to m/ s

Divide by 3.6

6

Acceleration

When a object Changes its velocity

7

Systematic error

Error caused by inn accuracy in the system

8

Example of systematic error

Measuring instruments not used properly or something wrong with instrument

9

Random error

Caused by unknown and unpredictable changes I. The experiment

10

Example of random error

Change in the environment
Electronics noise in electronic instrument

11
