Two motorcyle riders joined the trail bike riding. They were both excited since it was their first time participating in the said activity. As they were riding their motorcyle, an accident happened. Both riders lose their control. The first rider hit the concrete wall of the building while the second rider accidentally hit the csrnival's attraction, the bouncy castle. 1. Which rider do you think will be hurt more? Why? 2. Which rider will be safer? Why? 3. What type of collision happened in two motorcyle riders?

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
