Linear Acceleration Lab

Kinetic Energy is the energy of movement, whether it is horizontal or vertical, it’s kinetic. There is many different types of kinetic energy. There is; vibrational, rotational and translational (the movement from one location to another. IN our experiment we also have kinetic energy. The particles that move around need kinetic energy to bond because if the particles wouldn’t have kinetic energy, they wouldn’t move, then they wouldn’t be able to collide and at last there would be no chemical reaction taking place. But for a reaction to take place there has to be enough kinetic energy to overcome the bonding forces of the reactants. The minimum amount of kinetic energy need to cause a chemical reaction is called activation energy (symbol: Ea

The graph I created from the tested data differs from my predicted graph. They both are positive as the time increases as the position increases, but in my predicted graph, I did not count for acceleration. The reason the graph is not a

After the experiment had been conducted, the investigator concluded that the original hypothesis did not fit the outcome of the testing of the Beetle Robot. While it was hypothesized that the device would move and react in the same

In this lab, we applied the concepts of velocity,force, acceleration, time, and distance in order to calculate which trial had a higher velocity. We also learned the relationship between each of the factors and how altering one plays a role in the other factors. For example, if we were to apply more force the velocity of the cart would increase, as well as the amount of time it took for the cart to go down the

The Velocity Step Test measures gain and the time constant of the VOR by quickly changing the velocity of the chair when rotating left and right. Pre- and post-rotary nystgamus are measured at time constants of 60 and 240 degrees/second. Pre-rotary nystagmus time constant is measured during the 60- and 240-second velocity times and post-rotary nystagmus is measured during the 60- and 240-second stop times. The reason for using 60 degrees/second is to estimate the time constant and gain for the left and right horizontal canals. As the velocity increases, the time constant decreases and a percentage of VOR gain for the right and left can be compared. The test begins by accelerating the patient around 100 degrees/second2 stimulating the right peripheral system. The patient is spun to the right until maximum velocity is reached at 60 or 240

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.

Activity 7 was all about changing the strength in forces to make them unbalanced. When forces on an object are not equal, then it will move in the direction of the stronger force. According to Newton’s 2nd law, and some of our experiments, the equation F=ma is true. Force and mass are indirectly related, while force and acceleration are directly related.

The data collected agrees with Newton’s 2nd Law. Newton’s 2nd Law describes how the acceleration of an object is dependent on two things: the mass of that object, and the net force acting upon that object. As the mass of an object increases, its acceleration decreases. Our experiment directly relates to and agrees with this law of motion. The starting mass of our object was 653.7 grams, with an average acceleration of 0.8771 m/s².

Friction is the force that opposes the force applied on an object, as well as the motion of the object. The two types of friction covered in this lab are kinetic and static, but there are other types as well. Static friction ƒs opposes motion so that things do not move in relation to each other. Kinetic friction ƒk is the friction when objects are already moving in relation to each other. Examples of static friction and kinetic friction are riding a bike and moving furniture across the floor, respectively. It is important to note that friction is not dependent on the size of the area of contact between two surfaces assuming uniform surfaces. It is known that as the block pushes on the table, the table pushes back. This force is known as the normal force (ƒN) which is the equal force perpendicular to the object. In this experiment, it is noted that the table and room are stationary objects, and thus have no acceleration on them. This means that when the block is also stationary, the net force on the block is zero.

This clearly shows that the greater the force and the smaller the mass go towards making the acceleration greater.

Newton’s second law states that the acceleration of an object depends on the mass of the object and the force applied on the object. The first car that was built had a great amount of mass. The second car that was built had less mass than the first car. The same force was applied to both of the cars. However, the first car did not travel far because it had more mass. Even though the same size balloon was used for both cars, the one with less mass accelerated more than the one with more mass.

The purpose of this experiment is to test an Independent variable by collecting experimental data and its corresponding Dependent data. In this experiment it was tested what happens to a dynamic trolley or skateboard as different experimental variables are applied. Those experimental variables were different weights. Which means that this experiment is about the physics principles of the laws of motion and the inclined plane. The laws of motion are called newtons laws.

With the use of this experiment some conclusions have been drawn. For instance the main result is that the friction increases if one of the following variables increases: the weight of the box, the size of the box and the weight that is being pulled.

The coefficients of friction for this experiment were controlled by using the internet to find separate coefficients for the surfaces and objects used. A surface coefficient and the object coefficient were then added together and the answer was divided by two in order to find a final average coefficient.

In this experiment, frictional resistance, friction is studied. Friction is the force that is parallel to the surface and goes against the force of motion. Friction is dependent on the material of the two surfaces acting upon each other. Two types of friction were observed. Kinetic friction is the friction of two surfaces in motion. Static friction is the friction that must be overcome in order for an object to be in motion. Static friction will always be greater than kinetic friction because it requires more force to move a motionless object than it does to move an object in motion. The surface area, mass, and angle were observes in relationship to the coefficient of kinetic friction. Additionally, the ideal mechanical advantage (IMA), Actual mechanical advantage (AMA), and efficiency were observes as the angle changed.
