How do you develop the general velocity equation from a Velocity vs Time graph?

∙ 12y ago
Derivitives of a velocity : time graph are acceleration and distance travelled.
Acceleration = velocity change / time ( slope of the graph )
a = (v - u) / t
Distance travelled = average velocity between two time values * time (area under the graph)
s = ((v - u) / 2) * t

Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
How does kinetic energy relate to potential energy?
Think of potential energy as stored energy, and kinetic energy as energy that puts an object in motion (i.e., increases the magnitude of velocity). In general you can set them equal to each other, to for example determine the velocity an object will be atLet U = kinetic energy and K = kinetic energyU = mgh (mass, gravity, height)K = (1/2)mv2 (mass, velocity)If you set U and K equal to each other.U = Kmgh = (1/2)mv2masses cancel out leaving you withv2= 2gh (or about 20h)The higher an object is from the surface of the ground, the more potential energy it has. Looking at the equation I listed, you can see velocity get's higher as height increases. The velocity in this equation is what velocity it would be at the instant the object hit the surface.
Why average velocity of molecules of a gas is zero but the square of average velocity is not zero?
It depends on the sign of velocities. For example, if there are two velocities 7 and -7 m/s then the average velocity of the molecules will be 0. But, the square will be 49. The general thing here is that even if a velocity is negative, the square of EVERY velocity irrespective of the sign is positive i.e., squaring always removes the negative sign.
What is the mass of an object multiplied by its velocity?
The product of mass and velocity of an object is its momentum.
Is there a maximum speed an object can achieve if dropped from a great height and if so what is it?
Yes, that is known as the terminal velocity. At that speed, the air resistance (pulling up) would be in equilibrium with the gravitation (pulling down), so there is no further acceleration. The terminal velocity depends on the object's size and shape. In general, heavier objects will fall faster.Yes, that is known as the terminal velocity.

Why the force and velocity are in perpendicular direction?
In general, force and velocity do not have to be in the same direction; they can be at any angle.
How do you find the final velocity of a car when given its velocity acceleration and time?
The general technique is: Select a helpful equation from among the plethora to be found in your Physics text.Here comes one now:Final speed = (initial speed) + [ (acceleration) x (time) ]
Why do we calculate acceleration with velocity?
That's because of the way acceleration is defined. It is defined as the rate of change of velocity (change of velocity / time, or in the more general case, dv/dt).

How do you derive the equation e equals mc2?
E=mc2 is derived from the equation for kinetic energy Ke = mv2. The mathematics and concepts of special and general relativity shows that the absolute maximum velocity anything can have is the speed of light. The maximum amount of energy anything can possess is simply calculated from its mass and this maximum velocity squared.
What is the formula of vilocity?
in general velocity = mass x acceleration
What does travel velocity mean?
"Travel velocity could have two definitions. Travel Velocity is a web page that advertises and sells discounted airline, hotel, and other travel deals. Secondly, a general reference to travel velocity is the speed at which sound or light travels in relation Physics."
A vector is a quanitity with magnitude and?
A vector quantity is a physical quantity having magnitude and direction both. For e.g. velocity is a vector quantity and in physics it is velocity is generally denoted as: v (bar) = 2i+3j+4k where in general, i=velocity in x-direction j=velocity in y-direction k=velocity in z-direction 2,3 and 4 are magnitudes respective to their directions.

Does the speedometer of a car measure speed or velocity?
Velocity is the same as speed. Velocity is normally used in technical terms. Speed is a general term. The SI unit for velocity is m/s =Metres per second. People can relate better to Miles per Hour for a vehicle. It is still distance/Time.

How does speed travel?
Speed does not travel. The word speed is a general term for velocity.
