Detailed explanation-1: -Speed is a type of rate. A rate tells you the amount of something that occurs or changes in one unit of time. The SPEED EQUATION: To calculate the speed of an object, divide the distance the object travels by the amount of time it takes to travel that distance.
Detailed explanation-2: -Speed of a moving object depends on two factors–distance moved and time taken.
Detailed explanation-3: -The speed of the object depends on the distance it moves and the length of the time interval. The distance that an object moves is the length of the path that connects the points at which the motion of the object starts and ends.
Detailed explanation-4: -So speed depends on distance traveled, while velocity depends on the displacement.
Detailed explanation-5: -Speed is the ratio of the distance an object moves to the amount of time the object moves. The SI unit of speed is meters per second (m/s). Two ways to express the speed of an object are average speed and instantaneous speed.
