If the tape increases steadily in length, then the gradient is constant, and the actual acceleration always matches the sloping line which students have drawn on their graphs. Acceleration is then constant, or uniform. And in that case average acceleration, and acceleration at all times during the motion, are the same. Then: acceleration, a = (v-u)/t. We don’t have to spend much time talking about those markings that everyone uses: inches, feet, and the fractional 1/16-inch hash marks that make them up. But, it’s important to note that not all tapes are created equally. Some have helpful fractions printed in addition to the hash marks (1/8, 1/4, etc). Drill a .25 in (0.64 cm) hole through the center of the spot. To make sure the spot will actually work, test it by drilling a small, .25 in (0.64 cm) test hole through the material. If the drill makes it from one end of the spot to the other without running into trouble, you’ve found a good location. If it did not, cover the hole with putty and try again. [16] X Research source

Make sure the dryer vent hose is free of kinks and bends. Then, fix it to the wall using screws and pipe straps. For every 6 to 8 in (15 to 20 cm) of hose, use 1 pipe strap.

Then, slip the other end over the vent hood’s cap extension and secure it with a tube clamp or foil tape. [4] X Research source

Use your velocity axis to help you to work out the first velocity and the second velocity. You can call these u and v . (Remember that u comes before v in the alphabet, just as the first velocity comes before the second.) This introduces students to mathematical modelling of accelerated motion. Many students find the concepts challenging, and the introduction in a practical context is very helpful. Draw a straight line between the centres of the tops of the tapes. Draw a horizontal line from the centre of the top of the first tape. Draw a vertical line through the top of the second tape. You have made a right-angled triangle. The length of the base of your triangle, using the units of the horizontal axis, is 1 second. More common, but no less helpful, are tape measures with markings on both sides for taking both horizontal and vertical measurements. While you can measure vertically with any tape measure, having the numbers oriented vertically makes this task all that much easier.Here at Bright Tangerine, we’re proud to be active members of the filmmaking community. We’re also very Step 9 of the procedure: The dot at the start of second tape that students make is 50 spaces away from the very first dot they chose. The time between the first dot of their first tape and the first dot of their second tape is 1 second. The time between the middle of their two tapes is also 1 second. You may need to explain this.

Step 8 of the procedure: The length of each tape is the number of centimetres that the trolley travelled in a fifth of a second, or 0.2s econds. So students could multiply the length by 5 to find the velocity of the trolley in centimetres per second. The actual lengths of the tapes are fixed proportions of the velocity.

The procedure says nothing about the distinction between speed as a scalar quantity and velocity as a vector quantity. But since acceleration is a vector quantity we have chosen to write in terms of velocity. Find the gradient of the line connecting the tops of the two tapes. Measure the height of the triangle, using the units of the velocity axis, which are centimetres per second (cm/s). Divide the height of the triangle, in centimetres per second, by the base, in seconds. This gives you the average acceleration in centimetres per second per second (cm/s 2 ).
