The type of matter an object is made of and how that matter is distributed have an enormous effect on the objects mass. Another equation in Exploring Creation With Physical Science is this one: F= (mass) (acceleration). 2.1 Measuring Mass and Volume 31 At the speeds he was traveling, the car also had to besafe so safety features were designed such as roll-cage protection, a safetyharness, and an energy-absorbing steering column.How did his car reach such high speeds without using a motor? 4. Explain, step-by-step, using your own example. After many experiments, Mayers hypothesis that heat was a form of energy became the accepted theory of heat we believe today (Figure 2.4). How long (in seconds) will it take you to run 100 meters if you run Solved example problems can be at 5 m/s? For example, suppose you are given a speed and time and asked to find a distance. ofmass gram (g) a unit of mass smaller Mass than a kilogram; there are 1,000grams in 1 kilogram What is mass? The old explanation that science are heat was the fluid caloric was an incorrect hypothesis, one of manyhypotheses that leading up to the modern theory of heat. Suppose you are measuring the height of a small child. Rank these units from smallest to largest: micrometer, nanometer, kilometer, centimeter, meter. Mass vs. volume Can you think of something that has a relatively large amount of mass, but fits in a small space?
