For this experiment, you will need a 12” ruler, some nickels and quarters, and a triangular shaped piece of wood to use as a fulcrum. We are going to ask the question: How does moving the fulcrum point effect the distance a nickel can fly?

Balance the ruler so there is an equal length on both sides of the fulcrum (at the 6” mark).
Put a nickel at the one inch mark on the ruler. Record your observations in the data table.
Keep the nickel at the 1” mark. Drop a quarter on the end of the opposite end of the ruler from about 12 inches in height. Measure the distance from the end of the ruler to where the nickel lands. Record your results.
Repeat this 3 times.
Now move your fulcrum to the 9 inch mark and repeat steps 2-4.
Now more your fulcrum to the 12 inch mark and repeat steps 2-4. Which causes the nickel to fly farther? Which takes more force?

Which material produces static charge when rubbed?

Ogle–2013–blg–0723 is an exoplanet that is similar to earth in size and proximity to its star. this exoplanet has mass m=4.18×1024kg and radius r=5.66×106m. an astronaut whose weight on earth is w=735n lands on the planet. a. calculate m, the mass of the astronaut. b. calculate gp? , the acceleration due to gravity on the surface of ogle–2013–blg–0723. c. calculate wp? , the weight of the astronaut on the surface of ogle–2013–blg–0723. d. calculate v, the minimum velocity required to put an object into orbit above ogle–2013–blg–0723. e. calculate t, the time required to complete an orbit around ogle–2013–blg–0723.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
