11 godz. temu · In this video, we delve into the concept of average speed, a fundamental idea in the realm of time and distance. Whether you're a student grappling with phys...
5 dni temu · We will discuss here about the relation of Speed Distance and Time. Speed is defined as the distance covered per unit time. Speed = \(\frac{\textrm{Distance Travelled}}{\textrm{Time Taken}}\) Or, S = \(\frac{D}{T}\) Speed also requires a unit of measurement.
4 dni temu · A relationship between velocity, position and acceleration without explicit time dependence can be had by solving the average acceleration for time and substituting and simplifying t = v − v 0 a {\displaystyle t={\frac {\mathbf {v} -\mathbf {v} _{0}}{\mathbf {a} }}}
13 godz. temu · Figure 10.5.2: Connecting point a with a point just beyond allows us to measure a slope close to that of a tangent line at x = a. We can calculate the slope of the line connecting the two points (a, f(a)) and (a + h, f(a + h)), called a secant line, by applying the slope formula, slope = change in y change in x.
5 dni temu · This simple formula generalizes to define moment of inertia for an arbitrarily shaped body as the sum of all the elemental point masses dm each multiplied by the square of its perpendicular distance r to an axis k. An arbitrary object's moment of inertia thus depends on the spatial distribution of its mass.
2 dni temu · The Hubble length or Hubble distance is a unit of distance in cosmology, defined as cH −1 — the speed of light multiplied by the Hubble time. It is equivalent to 4,420 million parsecs or 14.4 billion light years.
5 dni temu · We will learn how to find the perpendicular distance of a point from a straight line. Prove that the length of the perpendicular from a point (x 1 1, y 1 1) to a line ax + by + c = 0 is |ax1+by1+c| a2+b2√ | a x 1 + b y 1 + c | a 2 + b 2. Let AB be the given straight line whose equation is ax + by + c = 0 …………………
