Questions:
1. Using the data you have gathered and your knowledge of the law of conservation of angular momentum explain the results for the angular momentum data column.
The angular momentum was different each time because the mass was different. If the mass was the same then the angular momentum would be the same because the law states that angular momentum will stay constant if in an
The cup will stay on the plate throughout the entire rotation because it will be moving in a circular motion. We can see that moving in a circular motion will cause it to stay on the plate because of the equation v= ωr. This equation relates the angular velocity (ω) and the linear velocity (v). When the cup is placed at the very center of the plate the radius (r) will equal zero. When zero is put into the equation for r, the right side of the equation will equal zero, leaving us with the equation v=0. Because v is the linear velocity, we can see that the cup will not move in a straight line, rather a circular
One of the best methods for determining mass in chemistry is gravimetric analysis (Lab Handout). It is essentially using the the mass of the product to figure out the original mass that we are looking for. Thus the purpose of our experiment was to compare the final mass in our reaction to the initial mass and determine the change in mass.
Vrock= Vcenter of mass + Wrock Where V is the translational velocity, and W is the angular velocity
This equation shows that mass will not affect the speed of an object, proving that whatever the mass of an object, the speed will always remain the same if all the other factors are kept constant.
When the eggs are dropped onto the pillow, the eggs will bounce a little and stay whole.
Q3: How do they feel each other before the last spin?How do we know this?
Angular momentum is the relationship between Rotational Inertia and Rotational Speed. More simply, it is the tendency an object has to continue moving in a circle or spinning.
Method: If momentum is conserved in a closed system, the total momentum of the system before collision should equal the total momentum of the system after the collision. Strobe photos will be used in the calculations that will prove that momentum is conserved.
The Grade 12 Physical Science learners at Penryn College were tasked with carrying out an experiment to investigate the effect of collisions on momentum. Different mass pieces (500g; 1kg and 1.5kg) were dropped on a moving trolley and the learners observed the velocity of the trolley before the mass pieces were dropped on the trolley and the velocity after the mass pieces were dropped. The velocities were then compared.
Collision Theory Experiment 1. What is the difference between a. and a Temperature increases the number of collisions. When the temperature increases the particles move quicker. If they're moving quicker, they are going to have more collisions. [ IMAGE] 2.
Title: Phases and Eclipses of the Moon. Purpose: The purpose of this lab is to demonstrate the different phases of the moon during its revolution around the earth and also to display solar and lunar eclipses. Hypothesis: I think that by following the procedure, I will successfully complete this lab in showing the phases of the moon throughout its revolution and the solar and lunar eclipses because I am moving the moon correctly.
Projection at an angle is when the trajectory is parabola and the object is projected towards the horizontal direction with an initial velocity. The maximum range of the hammer will occur when it is launched at 45o from ground level when air resistance is considered negligible. At this angle, the tangential velocity of the centripetal force (tension) and the tangential velocity of the force perpendicular to it (mgcosθ) are equivalent, resulting in optimal hang time, thus increasing the range. Circular motion is the orbit used to achieve the greatest initial velocity of launch when throwing the hammer. In hammer throw, the orbit is not horizontal or vertical circular motion as it is an angled plane. The athlete must exert a centripetal force in order to regulate the circular motion in which velocity accelerates before reaching optimal initial velocity of release. The centripetal force is the net force acting on the object while it is circular motion, this force acting towards the centre of the circle is described by Fc = mac, where ac = v2/r (Fc is centripetal force in N, m is the mass of the hammer in kg, ac is centr...
I will use the idea of centre of mass in this experiment. I know that
The absolute value of the slope, m, was then entered as the rate of respiration for the carbon (IV) oxide Gas Sensor in Table 2 then Ok as selected.
Throughout the past century, investigations of quantum and particle physics phenomena have proven to show the most significant concepts and ideas in the physical and sub-atomic world. However, the discoveries yet to be made are endless. One of the most fascinating concepts in the sub-atomic universe is the idea of spintronics. Spintronics is the quantum study of the independent angular momentum (not to be confused with the orbital angular momentum of the electron) of a particle, typically that of an electron (Introduction). An electron is a fundamental particle, with a negative charge, and is independently studied in the process of spintronic devices. The spin angular momentum of electrons is ±½ћ.
