The force of gravity causes objects near Earth's surface to fall with constant acceleration of 9.8 meters per second squared unless air resistance is substantial. Keep in mind that the integral of acceleration over time will yield velocity. Multiply the length of time the object has been falling...
This formula for the final velocity doesn't depend on the weight or mass of the cylinder. If you knew the weight of the cylinder formula in kg (technically, the mass) for different cylindrical objects, you could compare different masses and find their final velocities are the same, because ...
A wind is blowing directly from east to west. The pilot of a small plane finds that if he points the nose of the plane 28.9 ° north of east, his velocity...
How fast a bullet is traveling when it leaves the end of a gun's barrel, called the muzzle velocity, is of great interest to both those who work in the field of ballistics and physics students looking to cover a few key concepts in one, well, shot. If the mass m and muzzle...
Learn how to find the magnitude of a vector. Then, using a vector's direction and magnitude, learn how to create a vector and magnitude graph with...
The center of mass plays a critical role in defining angular momentum through the moment of inertia, and the center of rotation also impacts this quantity, as the radius could be changing with respect to rotation angle. References NASA: Angular Displacement, Velocity, Acceleration ...
The greater the object's mass, the larger its event horizon and the larger its radius. Regardless of how massive it is, a black hole's center point is what astronomers call a singularity -- a place where matter is infinitely dense. Of course, you'll have to find one of these objects...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flood-resilient structures, but relatively little is kno...
w = mg. The value of g on Earth's surface is 9.8 m/s3with units ofacceleration. To find the weight of something, simply multiply its mass by the value of the local gravitational field, and you get a result in newtons (N). For example, if your mass is 50 kg (about 110 pounds)...
Calculate the acceleration of a person or object by dividing the change in velocity by the time over which the change took place. For example, consider a race car that starts from rest, or zero mph, and accelerates to a final velocity of 155 mph in 6.1 seconds. A velocity of 155 mph ...
