When sitting in a science class and the teacher starts talking about motion and Newton’s laws, it may feel like he is speaking Greek. In reality, motion is the one thing all human beings understand very well.

Motion is when a body or an object moves with relation to time, changing its position. We experience motion from even before we are born – with the heart beat of the foetus inside the womb signifying movement of the heart and even when the baby turns or kicks, which is movement of the body.

Later on comes the crawling, walking and running with a lot of emotion attached to it. These emotions can be happiness, sadness, anxiety, fear, excitement, etc. and these also follow the laws of motion. There is a displacement of one feeling to another over a period of time due to some or other force.

While for some of us, it may be hard to picture molecules and atoms moving, colliding and vibrating in our body resulting in temperature fluctuations depending on the amount of kinetic energy involved… it may be easy to understand motion when looking at sports and cars. In all these cases, we start off with a body or object at rest which then has a force that acts on it and changes its position over a period of time.

Technology has improved in such a way that the speed of movement is even faster. For communication we now have e-mails and telephones. While some people may think an Aston Martin V12 is very fast moving from 0-100km/h in 4.8 seconds, the Barabus TKR actually beats that moving from 0-100km/h in 1.67 seconds. Athletes are running even faster, beating and creating new world records.

Motion is even more fascinating now than it was to Sir Isaac Newton when he came up with his Laws of Motion and to Albert Einstein when he brought relativity to the mix. Each new discovery brings a lot of emotions for humankind.
