This experiment aims to test the law of conservation of momentum by using cart and track system.

Procedure

1. Put two carts onto the track.
2. Hit the button on the cart so that they start to move at opposite directions. 3. Find the position where the carts hit the end at the same time. 4. Find the distance that each cart traveled.

5. Repeat step 1-4 with 500g and 1000g weights on one of the carts. Data and Calculation
m1m2=x2x1
The carts were measured to be 12cm each and weighting 500g each. And the total length of the track is 100cm. x1+x2 has a value of 76cm.

Theoretical Value of x1 and x2

0 grams of weight
500500=3838
500 grams of weight
5001000=25135023
1000 grams of weight
5001500=1957

Experimental value of x1 and x2
0 grams of weight
x1= 36 x2=40
500 grams of weight
x1= 24 x2=52
1000 grams of weight
x1= 20 x2=56

%error
0 grams of weight = 5.26%
500 grams of weight = 3.51%
1000 grams of weight = 2.63%

Conclusion
The equation m1x1=m2x2 or the conservation of momentum is proven true by this experiment. Even though there are % errors in these trials, these % error are insignificant. There are many sources of error in this experiment. Whether the carts hit the end of the track at the same time is hard to measure as it is measured by human reaction instead of the device itself. Furthermore, there are net external forces working on this system. The track itself was also not perfectly leveled.

...Collision and Conservation of Momentum
Collision, a normal phenomenon in our daily life, also is familiar by people in physics field. As we can imagine, there are many interesting among collision cause our attention to think about what is this exactly about and how does is work or maybe why is that such as there maybe some neutron stars intensely hurtling in outer space or two small eggs hitting each other. Outer space is filled with infinite particles that maybe...

Background Information:
Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved, which means that “momentum before an event equals momentum immediately after, or pi=pf”. Since pi=pf, then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an...

...Solving Momentum Problems
Momentum:
For lack of a better definition, momentum is a measure of the “oomph” that an object has due to its
motion. The more mass an object has and the more speed it has the more momentum it has. The
formula for momentum is simply:
p=mv
Where p is momentum, m is mass, and v is velocity
Note that momentum is a vector quantity, so it is possible to have negative...

...information collectors. This will measure the acceleration, velocity, and position of the cart as it moves down the track. The most important measurement collected is the velocity; which will be used to calculate the momentum.
We will also explore how mass impacts in the change of momentum, and if there can be a non-changing impulse between the two carts with different masses.

...CONSERVATION OF MOMENTUM PRACTICAL WRITE UP
AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system.
HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction.
METHOD: An air hockey table was set up and a video...

...What is momentum?
Momentum of a body is defined as the mass multiplied by the velocity of this object.
Momentum= m x v
Momentum and Newton’s second law of motion:
The resultant force is proportional to the change in momentum per a second.
We know that force = mass x acceleration. So F (mv-mu)/t
F m (v-u)/t = ma so F=kma
Momentum is a vector quantity:
Momentum has a...

...to study the principle of conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision.
Introduction:
When bodies collide with each other, the total momentum p = mv, is always conserved regardless of the type of collision provided no external forces are present. There are two types of collisions. In an elastic collision, both the kinetic...
