What are two factors that affect the gravitational attraction between objects? When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between […]
What happens if forces are unbalanced?
What happens if forces are unbalanced? An unbalanced force can change an object’s motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving. How does inertia influence your ability to roll […]
What force prevents a satellite from falling?
What force prevents a satellite from falling? Earth’s gravity Does space debris fall back to earth? According to NASA, an average of one cataloged piece of debris has fallen back to Earth each day for the past 50 years. Despite their size, there has been no significant property damage from the debris. Why is the […]
Why should you wrap your keys in foil?
Why should you wrap your keys in foil? So, when you’re out and about, here are two tips for protecting your keys. Because metal can block your key fob’s signal, you can wrap it in aluminum foil. While that’s the easiest solution, aluminum foil can leak the signal if you don’t wrap it tightly. Should […]
Why does magma rise to the surface?
Why does magma rise to the surface? Magma can rise when pieces of Earth’s crust called tectonic plates slowly move away from each other. Magma also rises when these tectonic plates move toward each other. When this happens, part of Earth’s crust can be forced deep into its interior. The high heat and pressure cause […]
What is quantitative scientific method?
What is quantitative scientific method? Definition. Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques. What is the use of quantitative methods? The purpose of quantitative research is to generate knowledge and create understanding about […]
How much does water reduce the weight of an object?
How much does water reduce the weight of an object? Fresh water weighs 62.366 pounds per cubic ft. Saltwater weighs 64.043 pounds per cubic foot. Comparing Equation 1 and 2 you can see that an object submerged in fresh water will lose less of its air weight to the bouyant force of the water than […]
What are two effects of heat?
What are two effects of heat? The important effects of heat on an object are listed below: Raises the temperature. Increases volume. Changes state. Brings about chemical action. Changes physical properties. What are the basic effects of heat? Prolonged exposure to extreme heat can cause heat exhaustion, heat cramps, heat stroke, and death, as well […]
How can you tell if a glacier is flowing?
How can you tell if a glacier is flowing? At the bottom of the glacier, ice can slide over bedrock or shear subglacial sediments. Fun Fact: Ice flow direction is determined by the glacier surface: a glacier will always flow in the direction the ice is sloping. What is it called when a glacier speeds […]
Why is an organization in a text very important?
Why is an organization in a text very important? Without a clear organizational pattern, your reader could become confused and lose interest. The way you structure your essay helps your readers draw connections between the body and the thesis, and the structure also keeps you focused as you plan and write the essay. What are […]
