How are gravity and weight related? Is gravity a constant force? How does distance affect gravitational force? The force of gravity between two objects depends on Is gravity an applied force in physics? What type of force is gravitational force?
weight = m x g where m is an object's mass, and g is the acceleration due to gravity. Acceleration due to gravity on Earth, is 9.8 m/s² — it never changes, regardless of an object's mass. That's why if you were to drop a pebble, a book and a couch off a roof, they'...
All of the major features of the sun can be explained by the nuclear reactions that produce its energy, by the sun's magnetic fields resulting from the movements of the gas and by its immense gravity. (Because of its size, the sun has enough gravitational force to hold all of the ...
How Do Airplanes Fly: Weight and Lift Every object on Earth has weight, a product of both gravity and mass. A Boeing 747-8 passenger airliner, for instance, has a maximum takeoff weight of 487.5 tons (442 metric tons), the force with which the weighty plane is drawn toward the Earth...
Is tension force and normal force the same? How to find tension on an inclined plane At what rate would a 20 kg box accelerate if it were pulled to the right with a 100 N tension at a 40° angle, in m/s^2? Why is the tension force equal to mass x gravity on an inclined plane...
Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow over the wing. In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as ...
1) How much net force is required to accelerate a 1500 kg car at 6.00 m/s2? Please enter your answer in the space provided: newtons 2) What is the mass of an object that has a weight of 115 N on the Moon? The gravity of the Moon is 1/6 of g (which is 9.8 m/s2). kg...
Boxing training also includes a lot of weight-bearing exercises that are vital for building bone density. These exercises involve any activities that involve working against your body weight and gravity, such aspush-ups. These activities force your muscles and bones to work harder than they usually...
Here's another way of looking at it: When you stand on a bathroom scale, it measures your weight because gravity pulls down on you and the scale. Because the scale is resting on the ground, it pushes up on you with an equal force -- this equal force is your weight. However, if yo...
Blood settles by gravity within the body, and there's a purple discoloration that occurs — that's called lividity. The body will become rigid. That's called rigidity or rigor ... People have looked at vitreous humor, which is the fluid in the eye; the corneas become cloudy ... You ...
