Threshold velocity is the minimum velocity required for an object to overcome a specific force or resistance and begin moving. It represents the point at which the force applied equals the force of friction or resistance, allowing the object to move steadily. It is often used in physics to analyze the motion of objects in different situations.

What is the threshold for low barometric pressure?
The threshold for low barometric pressure is typically considered to be below 29.92 inches of mercury (inHg) or 1013.25 millibars (mb).
What is the let go threshold?
The maximum level of electricity whereby a human has the ability to release their hands from an electrified object. Once this threshold is passed the electricity causes the hand to contract involuntarily and you can not release the object until the electricity is terminated or another force pulls your hand away.
If a person is standing still on the surface of the earth and the earth is rotating at 1500 km east what is that persons velocity?
The person's velocity would be 0 km/h since they are not moving in relation to the surface of the Earth. Their velocity would only change if they start moving relative to the surface, but standing still means their velocity is 0.
How fast you move and in what direction is called?
Speed and velocity respectively. Speed refers to how fast an object is moving, while velocity includes both the speed and direction of motion.
A sprinter explodes out of the starting block with an acceleration pf 2.3 ms2 which she sustains for 1.2 sThenher acceleration drops to zero for the rest of the raceWhat is her velocity at1.2s?
The sprinter's velocity at 1.2 seconds can be calculated using the formula: velocity = initial velocity + acceleration × time. Given the initial velocity is 0 m/s, acceleration is 2.3 m/s^2, and time is 1.2 seconds, the velocity at 1.2 seconds would be 2.76 m/s.
Is the threshold velocity for silt higher than the threshold velocity for sand?
No, the threshold velocity for silt is typically lower than the threshold velocity for sand. Silt particles are smaller and lighter than sand particles, so they require less energy to be moved by water or wind.
What do the following terms mean-Snells law-Threshold frequency-instataneous velocity-wave mechanics-Youngs modulus-zeean effect?
Snell's law is a description of the relationship between the angles of incidence and refraction. Instantaneous Velocity is the velocity at one point.
What type of material has the lowest threshold velocity?
Materials with low shear strength and cohesion, such as fine powders like talc or flour, generally have the lowest threshold velocity for motion to occur. This is because these materials have weaker interparticle forces that require less force to overcome to initiate movement.
When was From Threshold to Threshold created?
From Threshold to Threshold was created in 1955.
What has the lowest threshold velocity slit or clay?
Clay typically has a lower threshold velocity than a slit, meaning it requires less force to initiate movement. This is due to clay's fine particle size and cohesiveness, which allows it to be more easily displaced by lower velocities. In contrast, slits, being larger and more angular, usually need a higher velocity to overcome friction and initiate movement. Therefore, clay is more susceptible to erosion or displacement at lower energy levels compared to slits.
What is the minimum water velocity needed in a stream to maintain the transportation of the smallest boulder?
The minimum water velocity needed to transport the smallest boulder is determined by the critical threshold velocity. This velocity is influenced by factors such as the size, shape, and weight of the boulder. In general, for very small boulders, velocities in the range of 0.5 to 1.0 meters per second are often sufficient to initiate transport.
Why a long jumper runs before jumping?
Because jumping in place wont get you very far. To generate and store energy just before the leap. this gets them higher threshold velocity
What is a antonym of threshold?
anti-threshold
What rhymes with threshold?
There are no perfect rhymes for threshold.
Threshold of human in db?
The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.
How do you spell theshhold?
threshold - After the wedding ceremony he carried her over the threshold of their new home.
How to install a threshold on concrete?
To install a threshold on concrete, first measure and mark the placement of the threshold. Use a drill to create holes in the concrete where the threshold will be installed. Insert anchors into the holes and secure the threshold in place using screws. Make sure the threshold is level before tightening the screws.
