This is how Newton’s 1st law applies to my balloon powered racecar. Newton’s 2nd Law: To move a mass, you need a force. The racecar demonstrates Newton’s 2nd because the mass that you are moving is the racecar, and to move the racecar you need a force. The force is considered to be the air that releases from the balloon through the straw because this force allows the car to move forward. Newton’s 3rd Law: For every action, there is an equal and opposite reaction.
Centrifugal Force - Is the apparent force that draws a rotating body away from the center of rotation. It is caused by the inertia of the body. 8. Centripetal Force - Is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body, toward the fixed point of the instantaneous center of curvature of the path. 9.
The parachute descends at a constant speed, as it has reached terminal velocity. Variables There are a few possible variables that would affect terminal velocity of a parachute: • The shape of the object, would affect the air resistance, depending on how smooth or rough the surface of the object is. • The surface area of the parachute, which is also the size of the parachute, would affect the air resistance acting on the parachute, which will affect the speed that the parachute falls. • The length of the string between the parachute and the object
Answer the following questions: 1. Compare Aristotle's concept of inertia with the ideas of Galileo and Newton. In making your comparison, state the concept as each interpreted it (in your own words) and give the similarities and differences. Aristotle believed that the laws governing the motion of the heavens were a different set of laws than those that governed motion on the earth. As we have seen, Galileo's concept of inertia was quite contrary to Aristotle's ideas of motion: in Galileo's dynamics the arrow (with very small frictional forces) continued to fly through the air because of the law of inertia, while a block of wood on a table stopped sliding once the applied force was removed because of frictional forces that Aristotle had failed to analyze correctly.
The theoretical value was .04 kgm^s as opposed to .0488 kgm^2 which yielded a -22% error as shown in the data. Theory: The inertia for the disk rotating on the rotating apparatus can be found by using the integral of mass times the radius which results in the following formula: I(disk) = ½ MR^2 Where M is the mass of the disk being currently in the experiment, and R equal the radius of the disk. Inertia can also be found experimentally, but with the drawback of human and equipment error. I = M((R1)^2 + (R2)^2)/2 Where M is the mass of the object, R is the radius. There are two different radiuses.
This allows the driver to increase the down force on the rear wheels while turning to increase traction. Additionally the wing is used to increase drag during braking. The wing is stabilized in the lateral direction with a link arm utilizing spherical rod ends at each end. While cornering the link arm failed, causing a tire to blow out. Stress Analysis An important factor to determine is how much stress the stabilizing link needs to withstand.
HSC Syllabus Summary - Space 1. The Earth has a gravitational field that exerts a force on objects both on it and around it Students learn to: * Define weight as the force on an object due to a gravitational field. * Weight is the force on an object due to a gravitational field. This force is created by the gravitational field that surrounds the Earth: F=mg. This field, given by g=GMr2, (where g is the acceleration due to gravity or the gravitational field strength, G is he universal gravitational constant, M is the mass and r is the radius of the planet) acts on objects both on Earth and around it.
Assisted by Frank, Julia, Hannah, and ______ Abstract In this lab, Thermal Energy is being determined once the car starts from the top of a track, to the bottom of the track. Once the car starts at the top it has Potential Energy which is due to the objects position. As the car slides down the track, it creates Kinetic Energy which is due to an objects motion. The purpose of the lab was to figure out the Thermal Energy as the car slid down the track. Data was lead to figure out the Thermal Energy is J.
This also signifies that momentum is not conserved for inelastic collisions. Experimental Design Our experiment was divided into two major parts, the elastic collision and inelastic collision. Our setup was an air track with sonic rangers on each end. Two gliders were placed at opposite ends and pushed towards each other creating our collision. For the elastic collision we had the gliders set up so they would bounce off each other when they collided.
A roller coaster involves plenty of physics knowledge join together and makes it function. A sample of the roller coaster has shown above. In the beginning, carts are slowly moving to the top place by some mechanical devices like chain and motor (external energy force. Then, the potential energy is sufficient and starts to transfer the energy for the rest of motions. The principle of conservation energy states from ESA study guide: “energy cannot be created or destroyed but can be changed from one form to another.” When carts are on the point 1(top), the quantity of the gravitational potential energy is maximised, according to the formula of gravitational potential energy Ep=mgh.
