# Question: What Happens When Two Objects With The Same Momentum Collide?

## Can momentum be lost?

Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision.

If there are only two objects involved in the collision, then the momentum lost by one object equals the momentum gained by the other object..

## What happens if two objects of equal masses collide elastically in one dimension?

Figure 1: A special elastic collision for which two objects of equal mass initally move toward each other along a line. The result is that they exchange velocities so that the final velocity of each is the negative of its initial velocity.

## How do you know if a collision is perfectly elastic?

If the kinetic energy is the same, then the collision is elastic. If the kinetic energy changes, then the collision is inelastic regardless of whether the objects stick together or not. In either case, for collisions with no external forces, momentum is conserved.

## When momentum is transferred from one object to another their combined momentum remains the same?

Whenever an action and reaction such as this occur, momentum is transferred from one object to the other. However, the combined momentum of the objects remains the same. In other words, momentum is conserved. This is the law of conservation of momentum.

## Can a lighter object have more momentum than a heavier one how?

Question: Can A Lighter Object Have More Momentum Than A Heavier One? … No, Because Momentum Is Independent Of The Mass Of The Object.

## Does Momentum have direction?

Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an object’s motion.

## What is the formula for final momentum?

The Momentum Calculator uses the formula p=mv, or momentum (p) is equal to mass (m) times velocity (v). The calculator can use any two of the values to calculate the third.

## What is the relationship between mass and momentum?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

## What happens when two equal masses collide?

Elastic Collision, Equal Masses For a head-on collision with a stationary object of equal mass, the projectile will come to rest and the target will move off with equal velocity, like a head-on shot with the cue ball on a pool table.

## Is momentum lost when objects collide?

Momentum is conserved in the collision. … Momentum is conserved for any interaction between two objects occurring in an isolated system. This conservation of momentum can be observed by a total system momentum analysis or by a momentum change analysis.

## Can momentum be destroyed?

The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton’s laws of motion. … Momentum is conserved in all three physical directions at the same time.

## Does momentum change with direction?

Notice that momentum does not just depend on the object’s mass and speed. Velocity is speed in a particular direction, so the momentum of an object also depends on the direction of travel. This means that the momentum of an object can change if: the object speeds up or slows down.

## What is momentum in real life?

Momentum in a simple way is a quantity of motion. … If an object does not move then it has no momentum. However, in everyday life it has an importance but many people didn’t recognize it. Momentum is just about every activity that involves motion. It is an essential concept of physics.

## How do you find the momentum of two objects after a collision?

Multiply the second object’s mass by its velocity. For example, if it weighs1,000 and has a velocity of -30 meters per second, then its momentum will be 30,000 kg meters per second. Add the two velocities together to determine which way the objects will move after collision.

## Is momentum always conserved?

Collisions. In collisions between two isolated objects Newton’s third law implies that momentum is always conserved. … In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions.

## Does direction matter measuring momentum?

Two objects with the same mass will always have the same momentum. … Direction does not matter when you are measuring momentum.

## What are the 3 types of collision?

There are three different kinds of collisions, however, elastic, inelastic, and completely inelastic. Just to restate, momentum is conserved in all three kinds of collisions. What distinguishes the collisions is what happens to the kinetic energy.

## Can two objects have the same momentum?

When comparing the kinetic energy of two objects, the velocity of an object is of double importance. So if two objects of different mass have the same momentum, then the object with the least mass has a greater velocity.
