1.05 practical: investigate the motion of everyday objects such as a toy car or tennis ball

Apparatus: stop watch and metre rule

mark the start and end positions for the know distance 

use a metre rule to measure the distance 

line up front of car with start point, release and start timer 

move eyes to end point 

stop timer when front of car passes end point 

improve by repeating and averaging 

make sure car starts from stationary 

calculate average speed using : average speed = distance travelled/ time taken
