What Is Work?
Directions On the line, write the word or words that best complete the sentence.
1. When work is done, an object changes its
2. Work is done when a force moves an object in the
of the force that is applied.
3. To measure work, you must
through which it acts.
4. Work is measured in newton-meters, or
the force by the distance
5. The formula for measuring work is
Directions Use the formula work = force X distance to find each answer. Give the answer in joules.
6. Julie rolled a 2-kg ball down a ramp 10 meters long.
(Romamber 1 Iro 98 newtons.) How much work was done?

Pbco3 –> pbo+ co2. how many liters of carbon dioxide gas is produced from the decomposition of 32 grams of lead (ll) carbonate?

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.

What mass of glucose is produced when 54g of water react with carbon dioxide
