The first number is always one. If the ramp measures 12 feet long and the rise is 2 feet, you would divide 12 by 2 to get 6, and your ratio would be 1 to 6. Loaded forklifts must be driven with the load pointed up the ramp good standard practice is to ALWAYS drive with the load pointed up the ramp or slope.

At the exact same time as you start the timer, release the marble being careful not to give it a push as you let it go. At the same time, be ready with the marker to note the location of the marble after the second is up.
If you have a helper, have them watch the marble for you. Use the permanent marker to mark where the marble was one second after releasing it. How far did the marble travel? Repeat this process at least nine more times.
This means you should end up with at least ten different marks on the ramp, showing where the marble was one second after releasing it each time. Did the marble travel similar distances each time? Repeat this process, but this time mark where the marble is at two seconds after releasing it. Do this at least 10 times, so that you have made at least 10 more marks on the ramp. How does the distance the marble traveled after one second compare to the distance it traveled after two seconds?
Specifically, how does the distance between the starting line and the one-second marks compare to the distance between the one-second marks and the two-second marks? If you have a ruler, you can measure the distance the marble rolled each time from the starting line. Overall, how did the distance the marble traveled change as it rolled down the ramp for a longer amount of time?
What does this tell you about the effect of gravity on the velocity and acceleration of the marble as it rolled? Extra: Use a ruler to measure the marks you made on the ramp and calculate the average distance the marble traveled for one second and for two seconds averaging the times separately. Then graph your results, putting the average distance traveled on one axis and the time on the other axis. Based on your graph, how did the distance the marble traveled change as it rolled for a longer amount of time?
Extra: Try repeating this activity using a longer ramp, such as a flat board that is at least six feet long with a groove down the middle, or another straight piece of wood glued along the length of the first board to act as a guide.
Roll the marble down the longer ramp for increasing amounts of time one second, two seconds, three seconds, etc. On the whole I think my experiment went really well. I believe that I carried out my experiment reasonably, and I encountered no problems. As a result I ended up with an applicable set of results. I could carry out another experiment that would be quite similar to this one. I could investigate how the mass of a ball affected the speed. The two changing variables would be the weight of the ball and the steepness of the slope.
Fair testing and safety would be just as important. I would have to use the same apparatus and overall the same method. Also all the improvements I mentioned above I could use for this experiment.
I would predict that the ball with greater mass would roll down the slowest and the ball with the least mass would roll down the fastest. This is because a greater force would be needed to accelerate the ball with more mass, whereas a smaller amount of force would be needed to accelerate the ball will less mass. Also my preliminary run backs up my prediction as I can see that it took the three balls at the same height different speeds to roll down. Get Full Access Now or Learn more.

The higher something is the stronger the pull of gravity is, therefore, more energy will be transferred to kinetic energy from the potential energy the object has. E also increases proportionally 4 As the speed of the ball squared increases the kinetic energy exerted is also increased proportionally.
Therefore the graph would look something like this: As you are able to. This would allow me to compare my results to the one expected. I know that the Gravitational potential energy in the trolley was converted into kinetic energy when the trolley started to role down the ramp.
Every time a run was done the apparatus was re-checked to make sure the apparatus was still accurate. Each time the angle of slope was increased, the position of the light gate would have to be raised so the picket fence would not hit it. Preliminary Test 4: I will try and find out whether; the material of the ball bearing affects the speed of the period. Two types of energy: Kinetic Energy Potential Energy.

TP We will identify the relationships between objects and kinetic and potential energy by completing a lab P4L a skydiver releases 1,, Joules of. Force Motion Energy. For an object to move, there must be an application of force. Force is a push or a pull that causes an object to move, change direction,. Conservation of Energy. Similar presentations. Upload Log in.
