How to Solve Conservation of Momentum Problems in One Dimension Using Tutorials In Introductory Physics


Conservation of momentum is one of the fundamental principles of physics. It states that the total momentum of a system of objects remains constant as long as no external forces act on the system. In other words, the momentum before an interaction is equal to the momentum after the interaction.


One-dimensional conservation of momentum problems involve situations where objects move along a straight line before and after an interaction. For example, a collision between two cars on a highway, or a bullet hitting a target. To solve these problems, we need to apply the following steps:



Identify the system of objects and draw a diagram showing their initial and final velocities.

Choose a positive direction along the line of motion and assign signs to the velocities accordingly.

Write down the conservation of momentum equation for the system: pi = pf, where pi is the initial momentum and pf is the final momentum.

Substitute the values of the masses and velocities into the equation and solve for the unknown quantity.

Check your answer for consistency and reasonableness.

Here is what I added:


Let's look at an example of a conservation of momentum problem in one dimension and see how to solve it using Tutorials In Introductory Physics and Quizlet. Suppose two cars collide head-on on a straight road. Car A has a mass of 1500 kg and an initial velocity of 20 m/s to the right. Car B has a mass of 1000 kg and an initial velocity of 30 m/s to the left. After the collision, the two cars stick together and move with a common velocity. What is the final velocity of the cars?


To solve this problem, we need to follow the steps outlined above. First, we identify the system of objects and draw a diagram showing their initial and final velocities. We choose the positive direction to be to the right and assign signs to the velocities accordingly.




Next, we write down the conservation of momentum equation for the system: pi = pf. Since there are two objects in the system, we need to add their momenta before and after the collision. The initial momentum of the system is given by pi = mAvAi + mBvBi, where mA and mB are the masses of car A and car B, and vAi and vBi are their initial velocities. The final momentum of the system is given by pf = (mA + mB)vf, where vf is the final velocity of the cars. Substituting the values of the masses and velocities into the equation, we get:


pi = pf

(1500 kg)(20 m/s) + (1000 kg)(-30 m/s) = (1500 kg + 1000 kg)vf

(30000 kgm/s) + (-30000 kgm/s) = (2500 kg)vf

0 = (2500 kg)vf

vf = 0 m/s


The final velocity of the cars is zero, which means they stop moving after the collision. This makes sense because the initial momenta of the cars have equal magnitudes but opposite directions, so they cancel out.
