The net force upon the object according to observers in the rotating frame is F B = ma B. If their observations are to result in the correct force on the object when using Newton's laws, they must consider that the additional force F fict is present, so the end result is F B = F A + F fict. Thus, the fictitious force used by observers in B to ...
The type of throw used is highly influenced by the properties of the projectile: small, heavy objects are held and pushed away from the body (e.g. shot put); [7] handled objects are swung and released with one or two hands (e.g. weight throw, keg toss); [8] [9] smaller, lighter objects such as balls and darts tend to use an extended overarm ...
The object was 50-80 meters (150-240 feet) across and exploded 6-10 km (4-6 miles) above the surface; its explosion flattened 80 million trees and shattered windows hundreds of kilometers away. Asteroid impact avoidance encompasses the methods by which near-Earth objects (NEO) on a potential collision course with Earth could be diverted away ...
Levitation is accomplished by providing an upward force that counteracts the pull of gravity (in relation to gravity on earth), plus a smaller stabilizing force that pushes the object toward a home position whenever it is a small distance away from that home position. The force can be a fundamental force such as magnetic or electrostatic, or it ...
This is because gravitation is an attractive force, but if there is an underdense region it apparently acts as a gravitational repeller, based on the concept that there may be less attraction in the direction of the underdensity, and the greater attraction due to the higher density in other directions acts to pull objects away from the ...

Partially inelastic collisions are the most common form of collisions in the real world. In this type of collision, the objects involved in the collisions do not stick, but some kinetic energy is still lost. Friction, sound and heat are some ways the kinetic energy can be lost through partial inelastic collisions.
Well-built homes are reduced to a short pile of medium-sized debris on the foundation. Homes with poor or no anchoring are swept completely away. Large, heavy vehicles, including airplanes, trains, and large trucks, can be pushed over, flipped repeatedly, or picked up and thrown.
