2008年10月26日 · 1. How do you find the velocity of an object if you are given the x and y components of the velocity? 2. Not sure! 3. It makes the most sense to use the Pythagorean …

2016年7月14日 · Speed is a scalar quantity which means that there is no direction involved and is used for simple situations. When you get into physics, you start using velocity which is a vector …

2016年6月24日 · No it doesn't. You're mixing symbols with units, s is short for seconds. eg velocity is metres per second (m/s) In the kinematic equations (SUVAT) 's' is used to represent …

2012年9月3日 · Now we'd say that a velocity to the northwest is the sum of a positive north-south velocity and a negative east-west one. If we were talking about an airplane instead of a car, …

2012年9月29日 · In summary, the problem was to calculate the velocity of a San Francisco cable car at the bottom of a 30.4 m high hill when its brakes fail. Using the principle of conservation …

2015年9月23日 · It really has to do with energy. A given fluid flow has a finite pool of energy, and that pool comes from the energy stored as pressure and the kinetic energy of the moving fluid. …

2007年4月8日 · In summary, the position of a particle moving along an x-axis is given by x=12t^2-2t^3. To find the maximum positive coordinate, we can take the derivative of the position …

2011年2月8日 · A block of mass 0.3 kg and spring constant 24 N/m is on a frictionless surface. If the block is set into motion when compressed 3.5 cm, what is the maximum velocity of the …

2022年10月31日 · The viscous force will depend on the velocity gradient, but the viscosity is exactly what you can use to compute the viscous force given a velocity gradient. So, as …

2013年9月6日 · You can calculate the amount of torque required to accelerate the object, say from rest to a certain angular velocity. Your question is a bit unclear. If you want to determine …
