Molar mass

that every point mass attracts every other single point mass by a force. The force is proportional to the product of the two masses and inversely proportional to the distance between them squared. The equation is as follows, g=G m_ /r^ where g is the acceleration of gravity, G is the gravitational constant which is 6.673 x 〖10〗^(-11) N〖(m/kg)〗^2, m_1 is the first mass and r is the distance between the masses. We measure the force of gravity of Europa by using m_1 as the mass of Europa, and r

The movie 2 Fast 2 Furious defies the law of physics. Brian and Roman are trying to catch the luxurious boat so Brian starts to speed. It took him six seconds to go from 34.34 m/s to 52.75 m/s, he was going really fast. The car then crashes onto a concrete wall and flies into the ocean and makes it onto the boat on time. First off, when the car goes flying into the air, it is impossible for it to reach the boat. Gravity should be pulling it down, making it impossible to reach the boat. Instead of

Kinematics Cycle duration greatly decreased with increased speed within the walking gait and running at 4.5 mph (Fig. 2A,B; Table 1, 2). During walking, cycle duration was relatively shorter at slow speeds and low inclines, but longer at fast speeds and low inclines (Fig. 2B). There were significant differences in cycle duration between subjects, and interactions with cycle duration and subject, gait, and incline (Table 1,2,3). Step length statistically differed between subjects and showed interactions

The purpose of this lab is to study the principles on conservation of energy and conservation of momentum. We used a ballistic pendulum, which determines the speed of a bullet shot from a gun, to shoot a steel ball into a pendulum to create a completely inelastic collision. A completely inelastic collision is when two objects collide with one another, stick together, and move with the same final velocity in the same direction. In a completely inelastic collision, total kinetic energy is not conserved

resistance. We can look at the gravitational pull of the gymnast’s mass to earth and apply some of Newton’s laws of motion to

This lab was meant to act as an diagram that shows us the correlation between acceleration and force. My group wanted to figure out if adding force to the car would change the acceleration. Our hypothesis was, as the force increases the acceleration of the car would increase.We came to the conclusion that the independent variables would be the force and the dependant variable would be acceleration We create a scenario that would emulate the relationship between force and acceleration. We first obtained

Newton's three laws of motion have helped us get a clear understanding of how and why things happen. These laws are used even today, not only do we as students get an understanding of the world around us but these three laws have helped make discoveries/inventions and helped us with technological improvements. The video I have chosen is an example on how two of these three laws are put into work in a scenario. The video shows both a boy and a girl. The boy is driving the car while the girl enjoys

Diamondback Physics In Kings Island, there are thousands of examples of the three laws of motion. One of the more popular rides is the Diamondback. The laws that are in effect on Diamondback are the Concept of Energy, Law of Inertia, and the effects of weight during the ride. On Diamondback, it is clear that there are several forces acting on it because the coaster doesn’t have an engine it just uses the motion that it obtains from the hills throughout the ride. When the ride is in motion there

Introduction Free fall, which is accelerated motion that happens when an object falls with only the force of gravity acting on it (Hsu, Tom, Dr.). The speed of the tennis ball in y-direction will become 0m/s when the ball reaches to the peak and the acceleration will be 9.8m/s^2. Therefore, in order to find out the percent error for the time and eventually to predict the relationship between rolling speed and falling time, we can do this by using the equation: "y=vot+" 1/2 at^2, where y stands

Caption: This graph demonstrates the effect of total mass on the average acceleration of a coaster car. A clear decline in the average acceleration occurs as the total mass of the car increases. 1. The mass of an object directly affects the acceleration. The more mass an object has, the more the acceleration decreases. For example, when the car had 3 weights on it and weighed 1,457.9 grams, the average acceleration was 0.4116 m/s². When the car did not have any weights on it and weighed 653.7 grams
