Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
Average velocity
You need velocity at two points in time, and the acceleration must be constant. If the initial velocity is u ms-1 and the final velocity is v ms-1, and the time interval is t then t = (v - u)/a s.
To find the acceleration if the time is not given, you will need to know the velocity and the distance. Then, use this equation: d = vt + (1/2)at2 to solve the problem by plugging in your numbers for the distance and the velocity.
Distance = time * average speed (velocity) Average speed = Distance/time
It means there is no velocity - it is at rest and nothing is moving. The slope of the line is velocity - a horizontal line is zero slope = zero velocity
Acceleration
acceleration
acceleration or decceleration...
Acceleration equals the change in velocity over a period of time. a= (Vfinal- Vinitial)/t Plug in the acceleration and other information they give you. Then solve.
Acceleration is any change in velocity during a length of time.
Velocity
The rate of change in velocity in given time. By Suraj Kumar
That is called "acceleration". In symbols, that would be a = dv/dt; this means change in velocity divided by change in time, for a small time period.
Velocity is the change of distance over change in time (distance/unit time) and Acceleration is the change in velocity/unit time.
The rate of change in position at a given point in time is instantaneous speed, instantaneous velocity.
