If the force is doubled, this results in a doubling of the acceleration, and so on. Each repetition with the same force gives a similar acceleration. This avoids preoccupation with the calculation process, and greatly assists thinking about the relationship between acceleration and force.

The great advantage of this version is that the software presents acceleration values instantly.

This is a computer-assisted version of the classic experiment.

This relationship is indicative of Newton's second law of motion.

This is usually of the form 'acceleration is proportional to the applied force'. (Y axis: acceleration X axis: force.) Use a curve-matching tool to identify the algebraic form of the relationship.

The relationship between acceleration and applied force is investigated more precisely by plotting an XY graph of these two quantities.

Note the relative increase in values of acceleration as the slotted mass is increased.

Depending upon the software, the results may be displayed on a bar chart as the experiment proceeds.Repeat the above procedure for slotted masses of 300 g and 400 g.Enter '2' (2 newtons) in the force column of the table. Release the trolley from the same starting point as before. Transfer 100 g from the trolley to the slotted mass, to increase it to 200 g.Enter from the keyboard '1' (1 newton) in the force column of the table (see below). Repeat this measurement from the same starting position for the trolley several times.Observe the measurement for the acceleration of the trolley. Set the software to record data, then release the trolley.Position the light gate so that it will detect the motion of the trolley soon after it has started moving. Pull the trolley back so that the mass is raised to just below the pulley. It is informative to display successive measurements on a simple bar chart.

This should also include a column for the manual entry of values for force in newtons.

The difference between these, divided by the time between them, yields the acceleration.Ī series of results is accumulated in a table.

The internal calculation within the program involves using the interruption times for the two segments to obtain two velocities. The program should be configured to obtain measurements of acceleration derived from the double interruptions of the light beam by the card. Measure the width of each segment with a ruler, and enter the values into the software.Ĭonnect the light gate via an interface to a computer running data-logging software. Clamp the light gate at a height which allows both segments of the card to interrupt the light beam when the trolley passes through the gate.

This ensures that the total mass experiencing acceleration remains constant throughout the experiment.įit a double segment black card on to the trolley. Transfer them to the slotted mass holder each time the accelerating force is increased. Place the unused slotted masses on the trolley. The force is conveniently increased in 1 newton steps when slotted masses of 100 g are added. This produces an acceleration which is not too aggressive when the maximum force (4 N) is applied.

Fix a 1 kg mass on the trolley with Blu-tack to make the total mass (trolley plus mass) of about 2 kg. Choose a length of string such that the mass does not touch the ground until the trolley nearly reaches the pulley. Attach the other end to the trolley so that, when the mass is released, it causes the trolley to accelerate. Pass a piece of string with a mass hanging on one end over a pulley.
