What is the formula for aceleration?

Answer 1

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 / Δt

There is no equation for "deceleration" as suggested below.

Deceleration=(original velocity-final velocity)/Time

Deceleration In Motion

Deceleration = inital speed - final speed / total time taken

Answer 2

A landing craft of mass 12,000 kg prepares itself for a Moon landing. When at a vertical

distance 160m above the Moon's surface it's downwards velocity is 15 m/s. A retrorocket is

fired to give the craft an upward thrust to slow its speed to zero as it meets the surface.

Calculate the needed thrust to decelerate the craft its initial downwards velocity to zero as it

lands. The value for gravity on the Moon is

g/6. (Where g is 9.81m/s2).

Answer 3

There are so many formulas to remember in science, that it can be tricky. Acceleration is the rate a which an object changes its velocity. The Formula for Acceleration is velocity divided by time.

Answer 4

There are, of course, several formulae that involve acceleration. The basic definition of acceleration is: acceleration = delta velocity / delta time, that is, to get average acceleration, divide the difference of velocity by the time that passed. The same formula also gives you the instant acceleration, if the acceleration is constant.

If you want to get instantaneous acceleration, and the acceleration changes, then you need calculus: acceleration = dv / dt (that is, take the derivative of the velocity).

Answer 5

There is no formula for deceleration is physics so you can use the same formula for acceleration - use the answer in the negative. To calculate the acceleration, use a = (u - v) / t, where a is acceleration measured in m/s^2, u is the initial (starting) velocity, v is the final velocity, and t is time measured in seconds.

Answer 6

(Final Velocity- Initial Velocity)/ Time It's the same as for acceleration.

Answer 7

in classical mechanics acceleration is the force acting on the body divided by the mass of the body.

Answer 8

In physics, there is no "deceleration. " Using the formula for acceleration ((final velocity - initial velocity)/total time) backwards, you can solve for negative acceleration.
