How fast can you react to something that happens ? Suppose you are driving a car and suddenly see an obstruction in the road ahead. How long will it take you to recognize the obstruction and move your foot from the accelerator to the brake ? The time it takes you to do this is called your ______________. As you might imagine, reaction time is different for different______. Some people react very ______, and they make good race car drivers, airplane pilots and tennis players. Other just can't react ______, and such fast-paced professions are not for them.
Using the concept of free-fall and our equations of one-dimensional motion, you can do this experiment to measure your own reaction tine.

PROCEDURE


FOLLOW THE STEPS. EACH person in your group must do it.
Do it 3 times for each person and find the average.
Then compare in the class to find out who will make the best car racer.
Who should stick to Physics. FILL THE tABLE

	time1(s)	time2(s)	time3(s)	average time(s)
name : ________
name: ____________
name : _________

FIND out : IN the class, WHO HAS THE BEST REACTION TIME __________
THE WORSE __________________






CHECK HERE TO SEE if the time is consistent
