Speed, Distance and Time, Physical Science Game
What is the relationship between speed, distance, and time? Well, speed equals distance divided by time. Speed measures how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time taken. Basically, we can calculate speed if we know the distance traveled and the time taken. See how the concepts relate? Now, think about an Olympic sprinter and how time is critical to determining whether they are first or not. Play this science game to learn the relationship between speed, distance, and time.
Mechanics
The Mechanics of Speed is an essential part of physics, and the speed of an object is one of the most significant factors influencing its performance. There are two ways to measure speed: instantaneous speed and average speed. The latter is more important, as it explains the difference between the two. The average speed of a 100m sprint is a function of time, while the latter is the inverse of the average.
Firstly, you should understand the difference between speed and velocity. While both terms have similar meanings, they are not the same thing. The former refers to the rate at which an object covers a certain distance. The latter, however, has a direction. Likewise, the former is the rate at which an object changes its position relative to a given time. In simple terms, the greater the displacement, the faster the object is moving.
Techniques
Scientists study different types of speed. One type is linear speed, which describes the speed of an object travelling in a straight line. It can be calculated by applying Newton's laws of motion. Usually, scientists study the speed of an object at a particular time, such as when a boy is walking. This speed would cause the boy to change his position by two meters in a second. Another type is called instantaneous speed, which is measured at a specific moment. The difference between the two is that when an object falls, there is friction.
The average speed of an object can be calculated by dividing the distance it has covered by the time it took it to travel. However, the calculation of the velocity is more complicated. It can be done using different methods, depending on the information provided by the motion. Distance-time graphs are also helpful for calculating the speed of an object. It is useful to know the average speed of an object if you have a good idea of how much time it took it to travel.
