On this pumper/tanker fire engine, theprimary water tankis inside the vehicle, it holds1,000 gallons(3,785 liters) of water and it runs down the center in the rear of the truck. Adrop tankis like a big aboveground pool that can hold about2,000 gallonsof water. A 6-inch diameter, ...
What is Friction? Friction is the force that opposes the relative motion or tendency to such motion of two bodies in contact. If we try to push a block of wood across a table, there are two opposing forces that act: the force associated with the push, and a force that is associated ...
Does the coefficient of kinetic friction force depend on speed? Why is there frictional force? How can a small force impart the same momentum to an object as a large force? Why is rolling friction less than kinetic friction? Does kinetic friction act on sliding objects? How to find speed w...
According to Newton's second law of motion, force is directly proportional to acceleration. This means that the greater the force applied to an object, the greater its acceleration will be. How does friction affect motion? Friction is a force that opposes the motion of...
Learn what a non-conservative force is. Understand the differences between conservative and nonconservative forces and find non-conservative force examples. Related to this Question Why doesn't friction depend on surface area? Explain. Does friction depend on the area of contact? Explain?
Talking about ‘the weak nuclear force’, is a bit like describing friction as a force. Somebody who really understood friction, would not call it a force; rather they would explain it in terms of movement and electrical forces between the electrons and protons that make up atoms. ...
When the brake pad grabs the rotor, it creates friction, which creates heat. If that heat can't escape, it leads to brake fade, which reduces the brakes' stopping power. The second reason is gas build up. This actually isn't much of a problem any more; however, the materials used ...
Flint is an amazingly hard form of rock. If you strike iron or steel with flint, the flint flakes off tiny particles of iron. The force of the blow and the friction it creates actually ignites the iron, and it burns rapidly to form Fe3O4. The sparks that you see are the hot ...
Fourth: road conditions Different roads in the face of vehicle control effect is very obvious. The friction force of high speed pavement is stronger, and two kinds of cement and asphalt are used in the urban pavement. Asphalt pavement is different from high speed road surface. The ...
This is because the angle on the worm is so shallow that when the gear tries to spin it, the friction between the gear and the worm holds the worm in place. This feature is useful for machines such as conveyor systems, in which the locking feature can act as a brake for the conveyor...
