How Fast Does Sound Travel In A Mile? The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667
Did Motor Trend Buy Velocity Network? Did Motor Trend buy Velocity Network? Programming Parent Motor Trend Group Is Velocity channel now Motor Trend? The new home for your favorite Velocity shows and much more Starting Friday, November 23, Velocity will be rebranded as MotorTrend Network, the new cable home of shows like Wheeler Dealers, Bitchin’
Do Airplanes Have Constant Velocity? Do airplanes have constant velocity? Yes! In physics, constant velocity occurs when there is no net force acting on the object causing it to accelerate. In terms of airplane flight, the two main forces influencing its velocity forward are drag and thrust. How do airplanes control speed? The pilot controls
What Factors Influence Potential And Kinetic Energy? What factors influence potential and kinetic energy? The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy. What is the difference between kinetic and potential energy? Potential energy is the
What Does A Light Gate Measure? What does a light gate measure? Light gates will be used to measure the velocity of carts before and after they collide. The total momentum before and after the collision can then be calculated and compared. How does the light gate measure speed? The transmitter is usually a tiny
What Does DV Ds Mean? What does DV Ds mean? dv/ds is a differential form of velocity by displacement. Though this is not directly used for any purpose whatsoever, if you mutliply this with v, it forms v.dv/ds. v.dv/ds = a ; where a = acceleration and v = velocity. What does the D in
Does It Take A Stronger Force To Slow Something Down Then To Speed It Up? Does it take a stronger force to slow something down then to speed it up? For example if a ball is hit harder, it will speed up faster. If an object must be slowed down quickly, the force applied to
Does Drag Coefficient Increase With Velocity? Does drag coefficient increase with velocity? Where FD is the drag force, ρ is the mass density of the fluid; A is the reference area, and v is the relative velocity of the object in the fluid. The above expression means that a square increase in velocity decreases the
Does Distance Affect Speed? Does distance affect speed? Speed is the rate of change of distance with time. In order to calculate the speed of an object we must know how far it’s gone and how long it took to get there. “Farther” and “sooner” correspond to “faster”. Does speed depend on distance? So speed
Does More Force Mean More Velocity? Does more force mean more velocity? So, everyone thinks a greater force means an object goes faster. This is all the more reason to NOT say it – since it isn’t true. Then what do forces do to an object? They CHANGE the speed. It would be better to
