What happens when two objects with the same mass and speed collide?

Figure 8.7 shows an example of an inelastic collision. Two objects that have equal masses head toward each other at equal speeds and then stick together. The two objects come to rest after sticking together, conserving momentum but not kinetic energy after they collide.

What happens to the momentum when two objects collide and stick together?

If the two objects stick together after the collision and move with a common velocity vf, then the collision is said to be perfectly inelastic. In collisions between two isolated objects momentum is always conserved. Kinetic energy is only conserved in elastic collisions.

What is expected when two carts of the same mass move toward each other at the same speed and collide Inelastically?

Both carts come towards each other in a head-on collision. If both carts have the same masses and speeds then they will both come to rest after they hit the Velcro pads. This collision is completely inelastic: all the kinetic energy disappears.

What happens when two balls of equal mass collide?

Two balls with equal masses, m, and equal speed, v, engage in a head on elastic collision. Since the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero. For linear momentum to be conserved after the collision, both balls must rebound with the same velocity.

What happens in an inelastic collision between two objects with unequal masses?

in an inelastic collision between two objects with unequal masses, the momentum of one object will increase by the amount that the momentum of the other object decreases.

What happens in an elastic collision when the masses of the two objects are different?

15.4 Elastic Collision of Two Unequal Mass Objects A smaller mass approaching a larger mass will bounce back in a collision. If a larger mass is intially moving toward a smaller mass, both will continue with momentum in the direction of the intial momentum.

How does mass affect 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.

Do the two carts have the same momentum explain?

Is the magnitude of the momentum of each cart the same? Explain. Yes, the product of each mass and velocity gives the same momentum magnitude. No, the magnitude is different because they move in different directions.

Why do the two carts come to a stop at some time afterwards?

Any collision in which kinetic energy is lost is inelastic. Both carts come towards each other in a head-on collision. If both carts have the same masses and speeds then they will both come to rest after they hit the Velcro pads. This collision is completely inelastic: all the kinetic energy disappears.

Which of the following is true about what happens to energy when two balls collide?

Which of the following would transfer more energy? Which of the following is true about what happens to energy when two balls collide? The total amount of energy between the two balls becomes zero.

What is the relationship between the mass of the carts?

The mass of the carts is different in each situation. In each situation, total system momentum is conserved as the momentum change of one cart is equal and opposite the momentum change of the other cart.

What happens to momentum when two objects have different masses?

If the masses of the two objects are unequal, then they will be set in motion by the explosion with different speeds. Yet even if the masses of the two objects are different, the momentum change of the two objects (mass • velocity change) will be equal in magnitude.

Is momentum conserved in a perfectly inelastic collision?

Figure 8.7 A one-dimensional inelastic collision between two objects. Momentum is conserved, but kinetic energy is not conserved. (a) Two objects of equal mass initially head directly toward each other at the same speed. (b) The objects stick together, creating a perfectly inelastic collision.

What is an example of momentum conservation in physics?

As another demonstration of momentum conservation, consider two low-friction carts at rest on a track. The system consists of the two individual carts initially at rest. The total momentum of the system is zero before the explosion.
