If a bicycle and a massive truck have a head-on collision upon which vehicle is the impact force greater which vehicle undergoes the greater change in its motion?
which vehicle is the impact force greater? the bicycle.which vehicle undergoes the greater change in its motion? the bicycle
How do airbags help in preventing serious injury in a car collision?
Newton's First Law of Motion says that unless an outside force acts on an object, the object will continue to move at its present speed and direction. Automobiles consist of several objects, including the vehicle itself, the passengers inside and any other loose objects in the vehicle
Do insurance have devices to determine if a car was moving when hit or parked?
Yes, they have very effective and established investigative methods that can help them determine if a vehicle was in motion at the time of a collision.
What does the motion and collision between molecules cause?
Energy.
What vehicle uses all three laws of motion?
I believe every vehicle has the three laws of motion. All motion has them!
What law allows you to predict the motion of objects after a collision?
Conservation of Momentum
What is the difference in elastic collision and inelastic collision?
Elastic collision transfers more energy into motion while inelastic transfers energy into deformation of the objects. Elastic could be called more efficient transfer.
What is threshold for airbag deployment?
The following information was gathered from: http://en.wikipedia.org/wiki/Airbag ======= Airbags are designed to deploy in frontal and near-frontal collisions more severe than a threshold defined by the regulations governing vehicle construction in whatever particular market the vehicle is intended for. U.S. regulations require deployment in crashes at least equivalent in deceleration to a 23 km/h (14 mph) barrier collision, or similarly, striking a parked car of similar size across the full front of each vehicle at about twice the speed. International ECE regulations are performance-based, rather than technology-based, so airbag deployment threshold is a function of overall vehicle design. Unlike crash tests into barriers, real-world crashes typically occur at angles, and the crash forces usually are not evenly distributed across the front of the vehicle. Consequently, the relative speed between a striking and struck vehicle required to deploy the airbag in a real-world crash can be much higher than an equivalent barrier crash. Because airbag sensors measure deceleration, vehicle speed and damage are not good indicators of whether an airbag should have deployed. Airbags can deploy due to the vehicle's undercarriage striking a low object protruding above the roadway due to the resulting deceleration. The airbag sensor is a MEMS accelerometer, which is a small integrated circuit with integrated micro mechanical elements. The microscopic mechanical element moves in response to rapid deceleration, and this motion causes a change in capacitance, which is detected by the electronics on the chip that then sends a signal to fire the airbag. The most common MEMS accelerometer in use is the ADXL-50 by Analog Devices, but there are other MEMS manufacturers as well. Initial attempts using mercury switches did not work well. Before MEMS, the primary system used to deploy airbags was called a "rolamite". A rolamite is a mechanical device, consisting of a roller suspended within a tensioned band. As a result of the particular geometry and material properties used, the roller is free to translate with little friction or hysteresis. This device was developed at Sandia National Laboratories. The rolamite, and similar macro-mechanical devices were used in airbags until the mid-1990s when they were universally replaced with MEMS. Nearly all airbags are designed to automatically deploy in the event of a vehicle fire when temperatures reach 150-200 °C (300-400 °F).[citation needed] This safety feature, often termed auto-ignition, helps to ensure that such temperatures do not cause an explosion of the entire airbag module. Today, airbag triggering algorithms are becoming much more complex. They try to reduce unnecessary deployments (for example, at low speed, no shocks should trigger the airbag, to help reduce damage to the car interior in conditions where the seat belt would be an adequate safety device), and to adapt the deployment speed to the crash conditions. The algorithms are considered valuable intellectual property. Experimental algorithms may take into account such factors as the weight of the occupant, the seat location, seatbelt use, and even attempt to determine if a baby seat is present.
The motion and design of a vehicle?
What are some interesting guestions on motion and design i can research?
Which physical quantity remains constant in an elastic collision?
In a uniform circular motion,the magnitude of velocity remains constant,that is speed is constant,however due to change in direction in circular path constantly the motion is accelerated due to change in velocity.
What are the effects of friction on the performance of the vehicle?
It will slow down the vehicle and prevent motion.
What is avian ingestion?
Avian ingestion is the collision of a bird and an aircraft in motion, in which a bird enters a jet of an airplane.
