Gravitational constant

Explain how Newton 's first law applies to air bags, seat belts, and headrests. Newton’s first law applies to air bags, seat belts, and headrests in terms of keeping your body at rest while you are driving, which in turn will keep you safe. When you crash your car, the motion of your body in the car matches the motion of the century itself, so when it crashes, your body has the tendency to stay in motion. So, with the headrest, seatbelt, and airbag, they are all designed to slow down the forward…

of acceleration is zero because projectiles have a constant velocity, resulting in no horizontal acceleration. The y component of acceleration is a constant -9.8 m/s2 in relation to the gravitational force acting on the projectile. Why does the x component of velocity remain constant? The x component of velocity remains constant because since the horizontal acceleration is 0, then the x component of velocity (horizontal velocity) must be constant. The expression for horizontal velocity at any…

The weight of 100 grams was the controlled variable which means that it was held constant during the entire experiment. The mass was connected to the string which represents the independent variable since we varied the length of the string throughout the lab. We tied a loop on the string to hang it on the clamp so the weight was free…

Goal The goal of this experiment is to verify Newton’s 2nd Law of Motion. Introduction Newton’s 2nd Law states that when an external net force acts on an object, the acceleration of the object is proportional to the net force, and it also occurs in the same direction. The acceleration is also inversely proportional to the net force. Thus, the net force, which is the sum of all the forces acting on an object, is equal to the mass of the object multiplied by its acceleration. In this experiment,…

light-signal has to be transmitted relative to K1 with the velocity c, the propagation relative to the system K1 will be represented by the analogous formula x' - ct' = 0 _______(2) therefore: (x' - ct') = λ (x - ct) ______(3). Here λ is constant If we apply quite similar considerations to light rays which are being transmitted along the negative x-axis, we obtain the condition (x' + ct') = µ(x + ct) __________ (4). By adding…

energy is the energy of motion. This allows work needed to accelerate a body of a given mass from rest to its stated velocity. This use of energy becomes constant until the speed changes. Potential energy is when energy results from a position or configuration. This gives objects the capacity to do work as a result of its position in a gravitational field, an electric field or in a magnetic field. There are many electrical/power innovations that are known to be eco-friendly to our environment…

to Mars. The sols counted down with the amount of food and oxygen calculated until those sols, helped give the movie a more survival effect to help the mood of the movie. The plan to save the astronaut with the ship was brilliant, using Earth’s gravitational pull and slinging to Mars. The math and how the trajectory was explained helped make the movie actually seem realistic and provided better information. The idea of having scientist do the same work that the astronaut was doing on Mars, made…

certain staging, but in this particular painting such staging is conjugated with a sense of naturalness. Animal bodies are hung from high up, such as the deer, while others make way their way down, off the table and towards the floor, in a natural gravitational movement. I think that it is possible that all elements retain their assigned connotation and we may indeed approach them in this way, but another possibility is for…

energy)_(1-2)=1/2 mv^2 This formulation incorporates a number of simplifying assumptions. First, it ignores energy losses such as friction and aerodynamic drag that inevitably occur in real‑world mechanical systems. It also ignores the small change in gravitational potential energy that will occur between states 1 and 2 (from figure 2) as the projectile moves up the slider. Mechanical Efficiency of Ballista Mechanical efficiency is a quantitative measure of performance that is typically…

downward force which he later called gravity. Newton “created an equation to find the gravitational pull between the earth and the moon; 1/R2; where r represents the distance between two objects.” (Stern, Dr. David P. "(20) Newton 's Theory of "Universal Gravitation"" Newton 's Theory of "Universal Gravitation" Web. 4 Mar. 2015.). Newton also proposed that gravity is universal which keeps the planets in the gravitational pull of the sun. Even though many theories are used today for different…
