Physics Lab Report Impulse

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

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

Many things can’t be explained, but I have explained a few things that might seem confusing. If distance equals rate times time, than how fast the object is going, and how long the object is staying in the air is key. The machine that works faster and keeps the object in the air longer should be better than the other. Unless there is a difference in the objects, as such as one might be lighter, or float to stay in the air longer. Or if one object is more aerodynamic than the other.

The purpose of this lab is to calibrate two force sensors properly. Observe the directional relationship between force pairs. Observe the time variation of force pairs. We need to explain Newton’s third law in simple language.

Purpose: Analyze how Distance, Velocity, Acceleration are related and experimentally determine Acceleration due to Gravity. Background: The clicker speed in different countries vary because of differing voltage. It can be visually observed with the dots on the carbon strip how fast you have pulled it. When the dots are close to each other on the carbon paper means that you pulled the strip slowly.

The main objective of this lab was to measure the friction force it takes to start moving a weighted block across a table, and as it continued to move. This force was tested experimentally in three separate ways. The force was then solved graphically and mathematically through six different runs per method. TALK ABOUT RESULTS HERE.

The velocity that recorded from the photo-gate is 0.2m/s less than the velocity on average. Part 2: Table 2 shows the change of energy according to different mass. The heavier the cart is, the more GPE and KE it has. All the velocity is remaining in stable at around 2.34m/s. Because of wasting energy during the movement so the KE is slightly smaller than the GPE.

In science class, students were given a propeller and rubber band to add propulsion force to the car. The car without any changes used thick black wheels in the front and thin white wheels with tires in the back. It used heavier axles with the thick wheels and light, aluminum axles with the thin wheels and clay connecting the bearing to the axle. In the first iteration, clay was removed. The fifth iteration changed the wheels in the front from large wheels to thin wheels with tires. The sixth iteration changed the axle in the front to the same aluminum axle that was in the back. The car performed at its best after the sixth iteration because it traveled further distance and was lighter.

In order to calculate frequency, the free body diagram must be taken into consideration in order to calculate the force of tension. In this lab, the force of tension and gravity are assumed to be the only forces. Furthermore, the

My results from this experiment relate to known values of momentum as the results clearly demonstrate the affect of mass on the velocity of an object. My experiment proves Isaac Newtons third law of momentum to be correct, as the net force of a marble caused the acceleration of another marble. The distance the marble travelled depended on the net force, which in this experiment changed due to the different masses. When the mass of the marble was lighter, it had a decreased net force, causing it to have less momentum, as when it collided with the stationary marble the distance travelled was only 3.5cm. The marble containing the heaviest mass had a greater net force and impulse, affecting the change of momentum, as when the collision occurred the stationary marble had travelled 53cm.

In a pool game, the physics are the determining factor to almost every game. The balls must go into each pocket at the long edges of the pool table by letting the cue ball hit it. After it is hit, it heads into a specific direction based off the momentum, mass, and angle of the hit. This experiment will showcase the results of multiple collisions on two objects of equal mass. A certain physics equation, called elastic collision, demonstrates this mathematically. Elastic collision, given by 1/2mvc^2 = 1/2mva^2 + 1/2mvb^2, only applies if the momentum and kinetic energy of the objects colliding are conserved. Once the masses cancel, the equation is simplified to a familiar equation: the Pythagorean theorem, also known as a^2 + b^2 = c^2 (Real World Physics 1).

Using the toy cars and track, the lab was conducted to prove that the momentum before a collision would be equal to the momentum after a collision. The most significant results that was produced by the experiment was that the momentum before the collision, being 0.05929 kg*m/s, and the momentum after, being 0.0682 kg*m/s, were not equal like they should have been. These results from the lab were not accurate in the fact that the before and after momentums were not the same, which helps to show that lab measurements will be slightly off due to inaccuracy of the lab equipment.

An experiment was performed to determine the velocity of a toy car traveling in a straight line. A toy buggy car was set in motion and a marker was placed to indicate the location of the car every 2 seconds as measured on a stopwatch. The displacement of each marker from the starting point was measured using several meter sticks. This measurement was repeated using the same car 5 times. The average displacement and average deviation were calculated using Google Sheets, and the average displacement was plotted against time. The resulting graph appeared linear and the slope of the line was used to determine the velocity of the car. The velocity of the car was determined to be 0.38 ± 0.04 ms-1. An accepted value for the speed of the car was

For the third collision in part one, the change in momentum from initial conditions to final conditions was 28.7 percent. This is change in momentum indicates that an external force (such as a friction force) was present on the two cars. This friction force justifies the idea that the law of conservation of momentum is only applicable when there are no other outside forces acting on the system.3 This additional force explains why the percent in the change of momentum from start to finish is 28.7

Several systematic occurred in this experiment, but the most important one would have been the fact that the air hockey table was not completely level. This impacted upon the experiment in two ways. In the first experiment where the red puck is initially stationary, as the table was not level it moved around before the black puck collided with it. To overcome this the red puck had to be held in place and as mentioned before this would have provided and external force acting upon the puck. The unevenness of the air hockey table also meant that there was a possibility of friction acting on the pucks while they were moving. In the third collision with the Velcro another systematic error occurred. When the two pucks collided and stuck together they did not continue straight, instead they rotated. This is not linear momentum but rather it is angular momentum. This is reflected in the results as the magnitude of the initial and final momentum of the system is equal, but the
