Newton's second law of motion, net force equals mass times acceleration, tells us that if the acceleration equals zero, the net force must equal zero.根据牛顿第二运动定律,净外力等于物体的质量与加速度的乘积,因此如果加速度等于零,净外...
Area of a rectangle equals length times width.长方形的面积等于长乘以宽。 Force equals mass times acceleration. 力等于质量乘以加速度。 E = MC2. (Energy equals mass times light speed square.) 能等于质量乘以光速平方。 3)无论是表示次数或是倍数,三和三以上用times,两次...
The___(one) law says that the state of motion of an object doesn’t change until a force is applied toit.The second law of motion is called the law of acceleration(加速度). Itisoften___(write)as F=ma. Thatmeans“force___(equal)mass(质量)timesacceleration”.Thisisthemost important ...
B. Force equals mass times acceleration C. Every action has an equal and opposite reaction D. Objects at rest tend to stay at rest 2. What is the SI unit of electric current? A. Ampere B. Volt C. Ohm D. Watt 3. Which of the following is not a vector quantity? A. Velocity B....
(physics) the influence that produces a change in a physical quantity; "force equals mass times acceleration" impose urgently, importunately, or inexorably; "She forced her diet fads on him"同义词:thrust, do forcibly; exert force; "Don''t force it!" cause to move by pulling; "draw a...
What is now known as Newton's second law of motion sets down this relationship quantitatively: Force equals mass times acceleration, or F = ma. You see this equation in action every time you step on a scale. Your weight is actually the downward force that results from your body mass ...
In order for it to fly, the engineer has to rely on the same aerodynamics equation devised by physicists 150 years ago, which is based on Newton's second law of motion: force equals mass times acceleration. Problem is, the engineer can't reconcile his elegant design with the equation. ...
So, physics and marketing: We'll start with something very simple, Newton's law: "The force equals mass times acceleration." This is something that perhaps Turkish Airlines should have studied a bit more carefully (Laughter.) before they ran this campaign. (Laughter.) But if we rearrange th...
In summary: F=\frac{dm}{dt} \vec{v} + m \frac{d \vec{v}}{dt}.In summary, the equation \vec{F} = \frac{d \vec{p}}{dt}implies that force is a vector, is equal to the mass times the acceleration, and is a property of particles with mass. ...
