 # How to find acceleration of a body

For finding of acceleration of a body include a stop watch at the beginning of a piece of a way and mark its speed then mark speed at the end of a piece of a way and switch off a stop watch. Then divide the difference of initial and final speed in meters per second into time for which it changed in seconds. Acceleration also is through distance which passed a body.

## It is required to you

• stop watch, roulette, speedometer or the radar for determination of speed, the accelerometer.

## Instruction

1. Definition of acceleration through change of speed and vremyas measure by the help of a speedometer or the radar the instantaneous velocity of a body at the beginning of a way in meters per second, having at the same time included a stop watch. Through some period, measure instantaneous velocity again and switch off a stop watch, having received time for which there was a change of speed. After that find the difference of final and initial speed, and divide the turned-out number into value of time. The average value of acceleration in meters per second squared will be result.

2. Definition of acceleration without sekundomeras by the help of a roulette or in a different way, for example, a laser range finder, measure length of a way in meters which passed the accelerating body, having measured its instantaneous velocities in meters per second at the beginning and at the end of the studied piece of a way by means of a speedometer or the radar. After that build initial and final speed in the second degree and from the second degree of final speed take away the second degree of initial speed, divide it into length of a way and number 2. As a result receive value of average acceleration on this site of a way.

3. Definition of acceleration at the movement from a condition of a pokoyaesla a body begins the movement from a condition of rest, measure by a roulette length of a way which it passed also time for which there was this movement, respectively, in meters and seconds. Then length of a way needs to be increased by number 2 and to divide into the value of time built in the second degree. As a result receive value of acceleration.
