How is momentum conserved in your choice of two of these collisions?
In an elastic collision, momentum is conserved because the total momentum of the system before the collision is equal to the total momentum of the system after the collision. In an inelastic collision, momentum is also conserved overall, but some of the kinetic energy is transformed into other forms of energy, such as heat or sound, during the collision process.
What would have happened to the gas if the molecular collisions were not elastic?
If molecular collisions were not elastic, then some of the kinetic energy would be lost in each collision, leading to an overall loss of energy in the gas. This would result in a decrease in temperature and pressure of the gas over time as the molecules lose energy.
How does momentum change after a collision?
In a collision, momentum is conserved. This means that the total momentum of the objects involved before the collision is equal to the total momentum after the collision. The individual momenta of the objects may change based on the type of collision (elastic or inelastic), but the overall momentum remains constant.
Why if total momentum is zero but kinetic energy is not equal to zero?
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
What causes the transfer of momentum to the inside particles?
The transfer of momentum to inside particles is caused by collisions between the particles. When an external force is applied to a system, it causes the particles to collide with one another, transferring momentum in the process. This transfer of momentum results in the acceleration of the particles and the overall motion of the system.

Is momentum conserved if there is no friction?
Yes, momentum is still conserved even if there is no friction. In the absence of external forces, the total momentum of a system remains constant. Friction only affects the conversion of kinetic energy into other forms of energy, but does not change the overall momentum of the system.
What charateristics of molecules move firely and hit one another?
Molecules in a gas have high kinetic energy, causing them to move rapidly and collide with one another. This constant motion and collisions lead to the transfer of energy and momentum between molecules, creating pressure and contributing to the overall behavior of the gas.
Why does bouncing of an object result in a greater change of momentum rather than just colliding?
Momentum is the mass multiplied the change in velocity. If you think about it, bouncing an object means that it comes back from whatever it bounced against, giving it a negative velocity. This means that the change in velocity for bouncing is greater than for colliding because in an inelastic collision like the one described, the velocity goes to zero.
What happens to kinetic energy during gas particle collisions?
During gas particle collisions, kinetic energy is transferred between the particles. When two particles collide, one particle may lose kinetic energy while the other gains kinetic energy, depending on the relative masses and velocities of the particles involved. Overall, the total kinetic energy of the system remains constant due to the principle of conservation of energy.
How momentum can be used for safety features?
Momentum can be used for safety features by incorporating it into collision avoidance systems. By utilizing momentum calculations, vehicles can detect potential collisions and activate safety mechanisms, such as automatic braking or lane departure alerts, to prevent accidents. This technology helps improve overall safety on the road by using momentum to predict and avoid potential risks.
How does the kinetic energy of a bicycle contribute to its overall efficiency and performance?
The kinetic energy of a bicycle, which is the energy it has due to its motion, contributes to its overall efficiency and performance by helping it maintain speed and overcome resistance. When a cyclist pedals, the kinetic energy generated helps propel the bike forward, making it easier to ride and increasing its efficiency. Additionally, the kinetic energy allows the bike to maintain momentum, making it easier to climb hills and navigate obstacles. Overall, the kinetic energy of a bicycle plays a crucial role in enhancing its performance and efficiency.
How do collisions between molecules in a gas affect the overall behavior and properties of the gas?
When molecules in a gas collide, they transfer energy and momentum to each other, leading to changes in the gas's pressure, volume, and temperature. These collisions determine the gas's behavior and properties, such as its density, viscosity, and thermal conductivity.
