The pull of of gravity on an object determines its weight. The further you move away from an object, the more the gravitational force decreases. This is why astronauts feel weightless and float around in outer space. There is gravity on the moon but it is much weaker than that on Earth ...
No matter their weight, all objects fall to Earth at the same rate. Many factors affect how fast or slow objects fall to Earth. 2. Which of the following would create the smallest dent in space? Mars The moon Jupiter Earth Create your account to access this entire worksheet A Premi...

Gravity & Weight Weight varies with strength of gravitational force – mass doesn’t. Strength of gravitational force exerted on an object or person by the moon is 1/6 of the force exerted by Earth. Gravity and Motion Free fall – when the only force acting on an object is gravity. In ...
Science Background - Gravity: The centre of gravity of an object is where its weight is balanced. A low centre of gravity helps keep objects stable. As pupils tilt the bird model, its average weight moves higher and it becomes less stable. The downward force of gravity will always pull...

Gravity Gravity is the force that pulls objects toward each other. Gravity and Weight The gravitational force exerted on a person or object at the surface of a planet is known as weight. Weight = mass x acceleration due to gravity Acceleration due to gravity: 9.8 m/s2...
If you could travel from planet to planet your mass would stay the same, but your weight would vary depending on how the gravity of that planet pulled on you. Mars is smaller and has less mass than Earth and as a result it has less gravity. If you weigh 100 pounds on Earth, you wo...
The weight and position of the occupant, detected by four seat supports very similar to Type-S load cells, can be used to inform an adaptive ACU [43]. However, these supports are too bulky for implementation in a commercial vehicle and are too influenced by loads not aligned to the ...
(9.8 m/s 2 or 32 ft/s 2) Since the object is moving downward from the starting point, both y and v are positive numbers. When the depth d = 0, the value of g on the surface of the earth g d = g. When the depth d = R, the value of g at the centre of the earth g ...
