Newton's Second Law Practical Report

Newton 's three laws of motion play a huge role in our everyday life; from driving down the road and catching a baseball. Newton’s laws help us fully understand gravity, motion, and force in three easy-to-understand laws.

amount of force that varies in proportion to the product of the two objects ' masses, and in

where F is force (5N) , m is mass (5kg), and a is acceleration (you have to find acceleration)

Force is equal to the mass of an inert object multiplied by the acceleration of that body

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

The purpose of this experiment was to investigate the effects of different masses hoisted by an electric motor from ground level to a height of 1.29 m. The main purpose was to look how a change in mass affected the efficiency of our motor, but it did affect other variables such as power, current, force, etc. For this experiment, our hypnosis is that as mass increases, the efficiency increases. Because in the equation for efficiency, efficiency=gain in potential differenceelectrical energy used, gain in potential difference = mgh, the mass of an object has a direct relationship with the efficiency of the motor. In this equation, we see that efficiency is affected by the mass that is lifted, gravity, the height the mass is being lifted, and the amount of energy that is put into the system. We can see that mass, gravity, and height has a direct relationship while inputted power has an inverse relationship with efficiency.

recorded how far the items travelled. This showed me how Newtons Three Laws of Motion

In many of the comic books released by Action Comics #1, Superman is depicted holding a massive falling object such as an airplane, or a car using just one or both of his hands. This means that the entire weight of a falling plane or car is balanced on a section of area approximately the size of a human being's hands (Inglis-Arkell). According to Boeing, the average amount of weight for a Boeing 747 airplane that is full of passengers is around 115,000 kilograms (“Aircraft”). The average area of an adult male hand is 0.189 meters (Agnihotri). We are able to determine the force applied in newtons according to the equation Fw

The work offers an exact quantitative description of bodies in motion in three basic laws. The first law, known as the Law of Inertia, states that an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law states that acceleration is produced when a mass is acted on by a force. The greater the mass of the object, the greater the force required to accelerate it.

2. Why did increasing the voltage from 3 volts to 4 volts increase the force

A table of our findings from the five force analysis can be found in Appendix B, our

Dependent: Distance, Velocity, Acceleration Constant: Acceleration, Weight, Length of Carbon Paper Hypothesis: If the time it takes for an object to fall increases, then the distance it takes for the object will exponentially increase, the speed will increase linearly, and the acceleration will remain constant without a slope, because the gravitational force of earth is 980cm/s/s

1. Car have been designed to have less mass throughout the years. To make a car have less mass it must be designed to make it weigh less. If you have less mass, you have more velocity. The car’s mass depends on the parts of the engine.

Controlled Variable – Same amount of air resistant (stay in the same room), same surface of what the trolley is going to accelerate on, same trolley, have the string equally stretched out every time and same tick rate of the ticker timer. The controlled variable will be controlled to create a fair test.
