Use an air hockey table to investigate simple collisions in 1d and more complex collisions in 2d.
Making bonds energy marble collision lab.
You will need three different ramp heights 2.
Your marbles may be different in color.
To keep the marbles straight this lab will refer to the inbound marble as the blue marble and the marble that is sitting still on the track at the start as the white marble.
3 books 3 rulers 3 sets of different sizes marbles 2 marbles of each size paper clip rubber band stopwatch procedures.
Breaking an old bond requires energy from a collision.
A marble rolled down a ruler will push an object a student is curious about this.
Energy momentum purpose.
Asking questions analyze and interpret data mathematical thinking pes.
Vary the elasticity and see how the total momentum and kinetic energy changes during collisions.
The marble coming into the collision is called the inbound marble in this laboratory.
Thus we have to measure the velocity of cart 1 before the collision and the common velocity of the carts 1 and 2 after the collision.
The energy absorbed in breaking one mole of covalent bonds is called the bond energy.
You will measure the speed of each marble before and after the collision to determine whether momentum is conserved in this system for collisions between.
Whereas making a new bond releases energy in the form of heat.
Marbles roll away when you don t want them to if there.
Bond energy measures the strength of a covalent bond.
Marble collisions teacher version in this lab you will roll a marble down a ramp and at the bottom of the ramp the marble will collide with another marble.
In the first part of the lab we make sure that after the collision the carts stick together and move with some velocity common to both masses.
Set up a ruler two to form a ramp for your marbles a.
You will measure the speed of each marble before and after the collision to determine whether momentum is conserved in this system for collisions between marbles of varying relative masses.
The student sets up a ruler as a ramp and releases a marble down the ramp.
To see the momentum of a marble before collision and its kinetic energy materials.
In this lab you will roll a marble down a ramp and at the bottom of the ramp the marble will collide with another marble.
Experiment with the number of discs masses and initial conditions.
The stronger the bond to be broken the more energy is required to be taken in.
It is the same as the energy given out in making the same amount of covalent bonds.
In other words the rolling marble can only transfers its energy to the marble it collides with which transfers the energy to the next marble and so on.
In order to get the best results with this experiment you ll want to make sure that the surface you are working on is level.
The exact energy required for a particular old bond to be broken and a new one to be formed is called the activation energy.
