What is called the instantaneous speed of uneven movement? How to determine the body’s acceleration

1. What is called the instantaneous speed of uneven movement? 2. How to determine the body’s acceleration from the speed graph? 3. Where is the acceleration of the body directed during its acceleration? 4. Where is the acceleration of the body directed during its deceleration? 5. How to determine the movement of a body during its uniformly accelerated motion?

1. Instantaneous speed is the speed of a body at a given time.
2. Acceleration is the tangent of the angle defining the slope of the graph. (angle between graph and time axis)
3. During acceleration, acceleration is co-directed with speed.
4. When braking, acceleration is opposite to speed.
5.S = Vot + at ^ 2/2 or S = (Vo + V) t / 2 or S = (V ^ 2-Vo ^ 2) / 2a
