**How to Calculate Speed and Acceleration**

2
Speed Speed- the distance traveled divided by the time during which the motion occurred. Constant Speed- movement at a fixed distance per unit of time. The same amount of distance is covered by the object in the same amount of time at each measurement of that same interval. Instantaneous Speed-is the velocity of an object at a certain time. For example:- Suppose you are driving in a car with your father see the speedometer, its speed constantly varies, Because speedometer give speed at a particular moment of time.

Speed How to calculate it Distance Time

**Variables Expressed by**

Distance can be expressed in km (kilometers), mi (miles), m (meters), ft (feet). Time can be expressed in Hours, minutes, seconds, days. Speed can be expressed in m/s (meters per second), c/s (centimeters per second), km/ hr/ sec (Kilometers per hour over seconds).

9
Acceleration Acceleration- the rate at which velocity changes over time. An object accelerates if it changes speed or direction.
