Motorbikes and cars both have risks associated with operating them as modes of transportation. According to the WHO's Global Status Report on Road Safety 2018, which was published in December 2018, there are 1.35 million traffic fatalities worldwide each year. For people aged 5 to 29, traffic-related deaths now outnumber all other causes of death. Between 2011 and 2020, there were 2081 motorbike fatalities in Australia. (Survey of motorcycle accidents and statistics (2021). Almost 50,000 people will die in Australia as a result of motor vehicle accidents between 2012 and 2021. (Road trauma Australia - annual summaries 2021). To define the claim’s key term, “safer”, the physics of moving vehicles needs to be considered. Newton's laws of motion: A vehicle in motion is covered by this first law because it will keep moving forward in a straight line unless an unbalanced force such as that from a wall or tree or another vehicle acts on it. (Halliday, Resnick, and Walker, 2016) According to Newton’s second law, an object's acceleration is directly proportional to the force acting on it and inversely proportional to its mass (Halliday, Resnick). This law is particularly important for vehicles because it explains the impact of the mass of the vehicle and how the force being applied by the engine or brakes affect acceleration. Vehicles like motorbikes with a smaller mass have a greater acceleration for the same force which has an impact to the rider of the motorbike.
