MEASURING MOTION

A PERSON WALKING

PROCEDURE

• Measured distance from one side of the room to the other, in meters.
• Walked the distance from one side of the room to the other, while being timed with a stop watch.
• Repeated step 2, two more times to gather additional data.
• Calculated average time of 3 trials.
• Calculated speed by dividing distance across room by the average walk time.

Data Collected

SPEED=DISTANCE/TIME

• S= d/t
• S= 7.25m/ 6.57s
• S= 1.10 m/s
• My walking speed was 1.10 m/s

A TOY CAR ROLLING ACROSS THE FLOOR

PROCEDURE

• Measured distance from one side of room to the other.
• Rolled the car from one side of the room to the other while being timed, making sure that the car took the same path everytime.
• Repeated step 2, two more times to collect additional data.
• Found the average time of the 3 trials.
• Calculated speed by dividing distance across room by the average car time.

Data Collected

SPEED= DISTANCE/ TIME

• S=d/t
• S=4.85m/ 1.5s
• S=3.23m/s
• The speed of the car was 3.23 m/s.

CLOCK MINUTE HAND

PROCEDURE

• Measured the circumference of a clock using flexible measuring tape.
• Divided circumference by 60 to determine distance traveled by minute hand in one minute.
• Calculated speed by dividing distance from step 2 by 60 seconds.

Data Collected

SPEED= DISTANCE/ TIME

• S=d/t
• S=.002m/ 60s
• S=.00033m/s
• The speed of the clock's minute hand was .00033m/s.
