## YEAR 10 SCIENCE Ticker Tape Experiment

If this force serves as the action force, what is the reaction force in the action—reaction pair? Note that the total mass of the system remains constant as you increase the force acting on the system. This would represent an object that was speeding up because the dots are getting further and further apart. Then plot each displacement value in accordance with its time interval on a position-time graph. Then work out the initial 0. The time between the first dot of their first tape and the first dot of their second tape is 1 second. In conclusion, the velocity time graph of the cart down the ramp had a relative, if not completely linear shape. Aim: To measure the average speed of an object.

## YEAR 10 SCIENCE Ticker Tape Experiment

Answer: In order to find the acceleration, we need to determine the initial velocity, the final velocity and the time taken for the velocity change. The closer the dots are together on the tape, the slower the object moved. Method: Use the same basic method as for the Prac No. Materials -ramp -masking tape -recording tape -ruler -graph paper -loaded cart -power supply -ticker timer Controlled Variable: the ramp, the timer, the cart releaser, the testing environment, length of ticker tape, the angle of the ramp Independent: The average velocity of the cart per interval Dependent: The total displacement of the cart Method 1 A table was drawn to record time, displacement and average velocity. During this lab we were trying to find out the relationship between acceleration, force, and mass by using a air track, glider with picket fence, and photogates. Write this under S in Table 1.

## Some Help With My Ticker

Now record these measurements in a table like the one shown in the results section. See Figures 2 and 3. Improvements There are two major improvements that can be proposed to make the data collected from this experiment more precise and accurate. This is where a long tape is attached to an object that's moving. Would I calculate the average velocity, then divide that by t2 - t1? Draw a perpendicular from the point to the x-axis and then find tanθ.

The light gates are connected to the input terminals of a data logger as shown. Each vertical centimetre on your axis represents 5 centimetres per second. Analyse this section of the tape to complete the Table below. Write this under m1 in Table 1. The second object has twice the mass of the first object.

## Ticker Tape Diagrams

This leaves a line of dots on the tape, recording the object's motion. Divide the height of the triangle, in centimetres per second, by the base, in seconds. Relevant equations I am not positive which equations can be used, other than the tangent method, but as I previously stated, I am doing this incorrectly and would greatly prefer an equation if possible for the instantaneous speed. Report Aim: To calculate the acceleration of the dynamic trolley by using various methods. Release the car and measure the time taken for the car to move 1 metre down the air track. Note that the diagram below was copied from the notes supplied with Experiment M15 Inelastic Collisions from the Sensing Science software from Data Harvest.

You could say: Each period between dots is a 'tick' of time. This would eliminate the variation of places the car could start and finish from and the chance of the car falling of the board near the end of its run. One is a constant, fast velocity. Assume Renatta is traveling from left to right. The further apart the dots are on the tape, the faster the object moved. Aim: To determine the local value of the acceleration due to gravity using the ticker-timer.

## Ticker Timer Analysis

For each tape, glue the segments alongside one another, creating a speed versus time graph. Constant speed But what about acceleration? Plug the power pack into a power source. Attach the power pack to the ticker timer, by attaching 1 plug from the black negative output of the power pack to one of the power input of the ticker timer and have the other power input of the ticker timer attached to the red output positive of the power pack 3. I am having troubles getting from the d-t graph to the v-t graph. Why then do all objects, regardless of mass accelerate at the same rate when in free fall? After Heisenberg's discovery, the classical concept of the.

## Newton's Second Law

This is where a long tape is attached to an object that's moving. The acceleration due to gravity acting vertically downwards produces the weight force of each set of masses. Teaching notes 1 This introduces students to mathematical modelling of accelerated motion. We would like to suggest that you combine the reading of this page with the use of our Name That Motion Interactive. A problem I am having is accuracy, but the biggest problem I have is knowing when to stop the tangent. The results of part A can be seen in the table below. Increase the force on the system by transferring one 50g mass from the trolley to the mass carrier and repeat the experiment.

## Newton's Second Law

You can then edit the course to suit your students and local resources, exactly as if you had created it yourself. You have now completed the ticker timer motion analysis practical. Set up the equipment as shown in the following diagram. Hypothesis: As the slotted masses are added to the mass carrier, the acceleration of the system will increase proportionally. Results: Table: Analysis of data from tape Interval No. Answer: In order to find the acceleration, we need to determine the initial velocity, the final velocity and the time taken for the velocity change. Or, Force is equal to Mass x Acceleration.

## 8.4 Practicals

The far apart dots represent a faster-moving object. Continue until all of the 50g masses are on the mass carrier. Why not measure the length of each piece of tape, calculate the velocity, and plot a proper graph? Prac Report Problem: How does the increase mass affect acceleration and the force of the accelerating object? The distance between dots on a ticker tape represents the object's position change during that time interval. I recall watching a frequency meter at a power plant while on the night shift, and unless lightning took out a generator the frequency never varied as much as a tenth of a per cent. Then we found the total mass being accelerated in kg by adding the mass of the hanging glider to the mass of the hanging weight.
