Experiment 5: Relative Density Patrick Erlo Reyes‚ Joseph Winfred Sajul‚ La Reyna Roshele Salenga‚ Luisito Jeremiah Samonte‚ Christine Bernadette Sanchez Department of Biology College of Science‚ University of Santo Tomas España‚ Manila‚ Philippines Abstract This experiment is concerned with the densities of objects. The first activity is determining the density of a cylinder through displacement method and by weighing. The second activity is finding the density of a bone and determining it whether

Equations of Motion Worksheet 1. A car moving at a velocity of 25 m/s‚ accelerates at a rate of 6 m/s2. Find its velocity after 3s. 2. An object is dropped from rest. Calculate its velocity after 2.5s if it is dropped: a. On Earth‚ where the acceleration due to gravity is 9.8m/s2. b. On Mars‚ where the acceleration due to gravity is 3.8m/s2. 3. A motorbike is travelling with a velocity of 3m/s. It accelerates at a rate of 9.3m/s for 1.8s. Calculate the distance it travels in this time. 4. A Tesla
Premium Acceleration Velocity Kinematics
Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but

MOMENTUM QUESTIONS 1. Which has greater momentum: a train at rest or a moving skateboard? Since the train is not moving‚ it has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly

Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually
