# Linear Collision: Predicting Mass Motion

• pakontam
In summary, linear collision is a type of collision in physics where two objects collide in a straight line, resulting in a transfer of momentum and energy between them. The mass motion in a linear collision can be predicted by using the principles of conservation of momentum and energy. The outcome of a linear collision is affected by factors such as the masses and velocities of the objects involved, the angle of collision, and the presence of external forces. In a linear collision, the total kinetic energy of the system before and after the collision remains the same, as long as there are no external forces acting on the objects. This is known as the conservation of energy. Linear collisions can also be perfectly elastic if there is no loss of energy due to external factors, resulting

it is possible to predict the subsequence motion of two point mass after a linear collision, given ONLY their mass and velocity before the collision?
thanks.

Think about a billiards game. Would this be possible if your premise were true?

if you mean snooker, yes, it's possible to predict, based on the assumption that no energy is lost and the balls are of the same mass. (assume correct, is it?)
but u don't know the energy 'status' of the system after the collision, how do u predict?

## 1. What is linear collision?

Linear collision is a type of collision in physics where two objects collide in a straight line, resulting in a transfer of momentum and energy between them.

## 2. How can mass motion be predicted in a linear collision?

Mass motion in a linear collision can be predicted by using the principles of conservation of momentum and energy. By analyzing the initial velocities and masses of the objects, the final velocities can be calculated.

## 3. What factors affect the outcome of a linear collision?

The outcome of a linear collision is affected by factors such as the masses and velocities of the objects involved, the angle of collision, and the presence of external forces such as friction or air resistance.

## 4. How is kinetic energy conserved in a linear collision?

In a linear collision, the total kinetic energy of the system before and after the collision remains the same, as long as there are no external forces acting on the objects. This is known as the conservation of energy.

## 5. Can linear collisions be perfectly elastic?

Yes, linear collisions can be perfectly elastic if there is no loss of energy due to external factors. In a perfectly elastic collision, both momentum and kinetic energy are conserved, resulting in no change in the total energy of the system.
