Humans evolved with gravity, and gravity affects human physiology and general health. Studies show that weightlessness has a number of negative health effects. Finding ways to mitigate these dangers is essential for long... More »

Gravity primarily affects the development of a plant by influencing the direction of the growth of its roots in relation to Earth. A plant's root system generally responds to gravitational pull by growing earthward. The ... More »

Gravity pulls objects downward, toward the Earth’s center, so anything that flies must counteract gravity’s pull. Using forward thrust and the lift provided by wings, an airplane overcomes the effects of gravity and flie... More »

An object's acceleration is constant and downward due to the force of gravity In projectile motion, but the object's velocity reverses direction during the object's motion. This is because of the inertia described in New... More »

Assuming the stone starts from rest and air resistance is negligible, the depth of the mine shaft can be found by solving the equation x = 1/2 at^2, where "x" is distance, "a" is acceleration due to gravity, and "t" is t... More »

Electricity, gravity and magnetism are all examples of non contact forces. A force is anything that can cause a physical change in an object. More »

The specific gravity of diesel fuel oil varies between 0.81 to 0.96. Specific gravity of diesel fuel oil is recorded at 15.6 degree centigrade. More »
