Mass is the measurement of how much space an object takes up, and weight is the measurement of the pull of gravity on an object. Scientists measure both mass and weight with the use of balances and scales. The formula weight equals mass times gravitational force equates the two measurements.
An object has the same amount of mass no matter its location. The weight of an object changes from location to location because of the effects of gravity. This means that from planet to planet, the force of gravity and therefore an object's weight changes, but mass remains constant.
An object's weight also changes with the fluctuations in gravity experienced across Earth's uneven surface. In general, gravity weakens the further away an object or location is from the surface of a planet. This means that Earth's gravity is weaker at the top of a mountain when compared to the gravity felt at the bottom of the sea. By knowing the gravity of a location or planet and an object's mass or weight on Earth, scientists utilize the weight to mass formula to predict any expected weight changes.
The larger the planet, the greater the gravitational pull and the more an item weighs. For example, an item that weighs 200 pounds on Earth actually weighs 468 pounds on the much larger planet Jupiter.
Learn MoreMass is a measure of the amount of matter that an object contains, while density is a measure of how much mass an object contains per a unit volume. Mass is measured in kilograms, while density is typically measured in kilograms per cubed meter. Both are widely used in scientific formulas that are crucial for engineers, scientists and other professionals.
Full Answer >Mass does not affect speed directly, but it does affect how fast an object can change its speed by accelerating or decelerating. Objects with larger masses require more time for acceleration or deceleration compared to lighter objects.
Full Answer >Calculating how many feet are in something requires two steps: measuring the object and then converting the measurement into feet. The measurement can be made from any metric or English measurement of length, but the conversion requires knowing the ratio of the particular unit of measurement used to one foot.
Full Answer >The mass of an object is the amount of matter it contains while volume is the amount of space it takes up. Mass should not be confused with weight, which is the measure of the gravitational force on an object.
