Oct 17, 2024 · weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon.Weight is a consequence of the universal law of gravitation: any two objects, because of their masses, attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Pick up a book and then drop it on the floor. Why did it fall? It fell because of gravity. Gravity is a very strong force that pulls on objects. All objects experience the force of gravity pulling down on them all the time. On the earth, gravity pulls things down towards the center of the earth. It doesn’t push things up, only down. When you throw ...
An object will continue to fall and be pulled closer to the center of the earth until it is stopped by something, like the floor or a table. Even once it stops, gravity is still pushing down on it, but there is nowhere else for it to go, so it stays still. Since the earth is round, have you ever wondered why we don’t fall right off of it? What keep...
All things are made up of matter. Mass is a measure of the amount of matter that an object has, or how much “stuff” it is made up of. Weight is a measure of how much gravity pulls on a mass or object. On the moon, there is less gravity pulling on objects, so they weigh less. For example, a rock that weighs one pound while on Earth will weigh less t...
Mass– the amount of matter than an object is made of. Mass does not change with gravity. Weight– the amount of gravity acting on (pulling down on) an object (or mass). Gravity– a natural force that pulls objects downward. Earth’s gravity pulls us and all objects downwards towards its center. For science projects to use with this topic, visit our Ma...
Aug 25, 2020 · The mass of an object is the same everywhere. Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity. Mass of an object can never be zero. Weight can be zero if no gravity acts upon an object, as in space. Mass does not change according to location. Weight varies according to location.
The weight of an object is the gravitational attraction between Earth and the object. The gravitational field is represented as lines that indicate the direction of the gravitational force; the line spacing indicates the strength of the field. Apparent weight differs from actual weight due to the acceleration of the object.
The weight of an object is the force on it due to the gravitational pull of gravity at that point. Since it is a force, weight is measured in Newtons (not kilograms). The force of gravity is ...
This means that a 2 kg object on the Earth’s surface has a weight of 20 N (2 kg × 10 N/kg = 20 N). Mass and weight The mass of an object stays the same wherever it is, but its weight can change.

However, when objects on Earth fall downward, they are never truly in free fall because there is always some upward resistance force from the air acting on the object. Acceleration due to gravity g varies slightly over the surface of Earth, so the weight of an object depends on its location and is not an intrinsic property of the object. Weight ...
