Introduction: Newton ’s second law states "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force‚ in the same direction as the net force‚ and inversely proportional to the mass of the

The Rate of Locomotion dependence on hind leg length and body mass for the Tenebrio molitor beetle. Abstract The effects of leg length and body mass on the Tenebrio Molitor’s rate of locomotion were investigated under laboratory conditions. The performance (running speed) was accessed for 37 Tenebrio molitor with different hind leg lengths and body masses. Running speed is important for a variety of activities (e.g. searching for prey and mates‚ dispersal‚ etc.). Therefore‚ increased

How Does the Change of Mass Affect the Rate at Which an Elastic Powered Car Accelerates? Research Question: How does the change of mass affect the acceleration of the Lego Car powered by elastic? Hypothesis: it was thought that the more weight added to the body of the Lego Car would slow down the initial acceleration‚ but the car would travel a longer distance due to increased momentum‚ which might overcome kinetic friction. Rationale: Some reasons of why that it was thought
