When it blocks a second gate in can stop the timer. Some photogates are standalone devices, others will integrate with a computer. You can also set photogates to measure the shorter time that the beam is blocked as an object of a given physical size blocks the beam.
A tickertape machine emits a very creepy sound. This frequency is because of the frequency of Alternating Current electricity which powers the apparatus.
A long piece a ticker tape is attached to the moving object and pulled through the machine as the objects moves. A piece of carbon paper is placed between the vibrating stylus and the ticker tape. Each time the stylus bounces down, it leaves a carbon dot on the paper.
The distance between these dots can be measured with a simple meter stick after the experiment is performed. It is insightful to note that the faster an object moves, the greater the spacing between the dots.
Ultrasonic Motion Sensors are similar to the radar guns used my police officers to measure the speed of cars on the highway. The major difference is that these sensors use ultrasonic waves. She knows she will have to observe the object's motion.
She wants to see which surface material will allow a toy car to get down a ramp in the least amount of time. Ashley will be investigating which car gets down the ramp in the least amount of time. The keyword "time" in that statement gives a clue to which answer choice would be the correct measurement.
The only answer choice that measures time is, "Ashley will measure the time it takes for each car to go down the ramp. This choice would collect information about each car so their times can be compared. The vehicle with the least amount of time would be the car that travels down the ramp the fastest. Cindy rolls a marble down a ramp and hits a cup waiting on the bottom. She does this multiple times with different size marbles. After each roll, she measures the distance the cup traveled.
The tool that would be most appropriate for measuring would be a ruler. This investigation is measuring distance so that would narrow the choices down to a ruler or the meter stick. A meter stick measures things that are a longer-distance, and a marble is not going to move a cup that far.
A ruler would be sufficient for this investigation. Jamarcus is experimenting at his local playground. He and his friends are all wearing pants made of different materials. They want to see which type of pants will move down the slide quickest.
This experiment is testing which pants' material will slide the fastest. This is a measurement of time and speed. The tool that would be the most appropriate would be the stopwatch.
The boys could time each person from the top of the slide to the bottom to determine who's pants help them to slide the fastest.
The person with the lowest time is the material that allows the quickest slide. Which tool would be most appropriate for measuring how high the ball bounces in this experiment?
Use the data table below for additional information. In this scenario, the students measure distance, and they measure up to 20 inches. A yardstick would be most appropriate because it uses the correct units of measurement and would reach the necessary length to complete the measurements.
What would be the most appropriate tool to measure the weight or mass of the marbles in the data table below? This data table shows the marble's weight is in grams. To measure the marble accurately, a scale should be used to find its weight or mass. A beaker and measuring cup would be more appropriate for liquids, and a ruler measures length.
A scale or balance would be the best option for weight or mass. Grant wants to investigate how objects move and see if he can make correct predictions. He knows he will have to observe the object's motion. He wants to see if a soccer ball will travel further on artificial turf or real grass. Grant will be investigating whether a soccer ball travels further on artificial turf or real grass.
The keyword "further" in that statement gives a clue to which answer choice would be the correct measurement. The only answer choice that measures distance is, "Grant will measure the distance the balls traveled on each type of grass. This choice would collect information about each grass type and the distance the balls traveled so they can be compared. Jamarcus and his friends should measure the distance from the top of the slide to the bottom of the slide. They should record the measurement and then determine which person is the tallest.
They should record the measurement and then determine which person is the shortest. Jamarcus and his friends should start timing each person as they begin sliding to when they reach the bottom. They should record the measurements and then compare them to see which material had the shortest time.
They should record the measurements and then compare them to see which material had the longest time. If the student wishes to make observations about an object's motion, taking measurements is an excellent way to record the data and draw conclusions. The student could measure the speed of the objects, its distance traveled, or the amount of time it was moving.
All you need to do is move and tap. You can use a smartphone or one of our more specialist Moasure tools, the principle is the same, tap to begin measuring and touch down and hold to finish and let Moasure do the rest. It is that simple, you no longer need a box of tools, one measure, lots of easy measurements. And a small tool at that, Moasure ONE will fit into the tightest spaces and works just as easily in the dark as in very bright light.
As you touch down from one point to another Moasure plots each position and calculates all the relevant measurements at the same time. So, if you take a straight-line measurement from one wall to another, Moasure will calculate the A to B measurement, but it will also be able to calculate the difference in height, level or angle between the two points. Moasure is an incredibly smart measure, working powerfully with all the data it collects.
Touch the diagonal corners of a room and Moasure will produce length and width measurements and calculate the 2D area of the room all at the same time.
