What is the formula for aceleration?
The first answer is backward. Acceleration = (final velocity - initial velocity)/total time. For deceleration the formula is the same, the answer will just be negative.Agreed. In physics, there is no "deceleration", only negative acceleration.a = Δv / ΔtThere is no equation for "deceleration" as suggested below.Deceleration=(original velocity-final velocity)/TimeDeceleration In MotionDeceleration = inital speed - final speed / total time taken
How is the speed of moving object measured?
Speed is measured by dividing your time into distance to come up with your velocity. speed is measured the same way as velocity. If you have a varying speed with acceleration and deceleration this would need to be factored in as well.
A ball thrown up vertically returns to the thrower after 6 seconds find the velocity with which it was thrown up?
The velocity changes from [ V upward ] to [ V downward ].The total change in velocity is [ 2V ].Acceleration = (change in velocity) divided by (time for the change) = 2V/6But the acceleration is just the acceleration of gravity = 9.8 meters / sec2 .9.8 = 2V / 62V = 58.8V = 29.4 meters per second upward
What is the definition of decreasing velocity?
Velocity is a vector so it has magnitude (size) and direction. so to change velocity all you need to do is slow down or speed up or change direction. This is also known as acceleration which is the rate of change in velocity. Velocity is a vector so it has magnitude (size) and direction. so to change velocity all you need to do is slow down or speed up or change direction.

Should acceleration be constant?
Acceleration must be constant to use kinematic equations. Acceleration need not be constant if working with energy.
A braking time of 1.5 to 2 seconds what is the final velocity?
You need more details.The final velocity could be 0However, you need to know the initial velocity, and the braking acceleration, and perhaps other acceleration/deceleration factors to know the true answer.
Which variable frequency drive should I use for a 1.5 ton inverter AC?
You do not need to use an external variable frequency drive for the said AC. You have mentioned that it is inverter AC. It means the AC is already fitted with a built in inverter. Even if you connect an inverter to the AC, you need another control device to control the VFD to control the speed of the fan/ compressor depending upon the room condition, external temperature, temperature setting etc. It is little complicated.
Why does my 1999 CE Lancer shake under acceleration from 80kph onwards totally smooth on deceleration?
It is possible you need to have the front wheels balanced. Unbalanced wheels will cause vibrations at certain speeds.
How a frequency inverter operates?
The frequency inverter changes the frequency of power lines to the electric motor, hence to change the speed of the motor, in some applications like conveyor, it does not need full speed running all the times, so the frequency inverter comes in as the speed control role to save electric energy.

How do you speed up?
To speed up, or slow down, or change direction, are all forms of acceleration (to a physicist at least; in the world of non-physicists, the term deceleration is generally used to describe slowing down, as distinct from acceleration) and as Isaac Newton pointed out, hundreds of years ago, force equals mass times acceleration, from which we may infer that what you need to speed up is force.
I have a 5kVA inverter and the inverter will be off always. when the main source fails the inverter should feed supply to laod. in this case my inverter is overloaded due to initial surge. what to do?
To prevent you backup Inverter from sudden overloading. You should manually control your Inverter. When power fails. Shut down all loads. Turn on your Inverter with a with no loads on the AC line. The slowly begin to turn on loads to your backup Inverter. Start with just the lighting systems and then work you way to higher current loads such as Air Conditioning Units. Another way to solve your problem is add maybe 5 additional Units in parallel. You need to calculate all the power loads in your house is using making sure your inverter can handle the complete load. Why the Inverter fails is due to high inductive loads. The Inductive loads appear as a short circuit to you Inverter. The only way around that problem is to limit the number of inductive loads the your Inverter is supplying power to.
Introduction of DC to ac inverter?
A DC to AC inverter takes a DC voltage input to a AC voltage output. So if you have a 12v battery and need to run a 120v AC tool or something. All you need to do is plug a inverter to your battery and plug your 120v tool the the inverter. Takes all there is too it.
Why does a car need force from its engine when moving at a constant speed?
If there be no force ie no deceleration then no need to apply any force to compensate such a deceleration. But deceleration is there due to frictional force between the tyre and the road. Hence to compensate this we have apply acceleration. So force is needed OK Physics laws State that an object in motion will remain in motion until acted upon by an outside force. The car moving at a constant speed is being acted upon by wind resistance, gravity, and friction. Therefore force is needed to retain the constant speed
What size of an inverter generator would you need to run a MacBook Pro?
Look on the AC power adapter and read its rating in watts. You will need an inverter with at least that output capacity.
Which kind of inverter is needed to run a table fan?
The voltage and frequency should be marked on the fan. This should match the voltage and frequency of the power coming out of the inverter. The inverter also has be capable of supplying anough power (in watts).
