Why is it one half at squared?
If you just set the initial position and velocity equal to zero, this reduces to the equation you cited. So you can see that the factor of 1/2 comes because we can conside the average velocity of a moving body by simply taking half the sum of its initial and present velocities.
Why is 1/2 GT squared?
When a body falls under gravity when it’s initial velocity is zero and acceleration is due to gravity and g remains fairly constant when height h is not large, the equation reduces to the form h= 1/2gt².
What is UT plus half at Square?
Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2).
What is half GT Square?
The title equation, s = 1/2 gt 2, gives the distance s fallen by an object in a time t, assuming the object starts at rest and that air resistance is negligible; g is the acceleration of gravity, which is about 9.8 m/s2 on the surface of the Earth.
What does GT square mean?
When an object falls, it goes a distance d in time t according to the formula d = (1/2)gt2. d is distance in meters, g is gravitational acceleration in units of meters per second squared and t is measured in seconds.
What is 4x squared?
What is the square of 4x?, You cannot take the square root of x as it’s multiplied to 4. However, if the equation was what it is the square root of 4x ^2, then the answer would be 2x. However, that is not the case. Therefore, the answer for the square root of 4x is simply the square root of 4x.
What does 1 sq ft equal?
What is a Square Foot? A “square foot” is a unit of area measurement equal to a square measuring one foot on each side. 1 Square Foot = 0.0929 square meters. Abbrev.: ft2, sq.ft, SqFt.
What is a perfect square?
A perfect square that ends with 0 will always have an even number of zeros at the end.
What is the formula for sin x?
sin (2nπ + x) = sin x, n ∈ Z sin x = 0, if x = 0, ± π, ± 2π , ± 3π, …, i.e., when x is an integral multiple of π Sometimes, we can also write this as: sin x = 0 implies x = nπ, where n is an integer Thus, we can say that the value of sin x repeats after an interval of 2π. Therefore, the period of sin x is 2π.
