Consider a plot of the displacement (x) as a function of the applied force (F) for an ideal elastic spring. The slope of the curve would be

the reciprocal of the spring constant

Is it possible for a system to have negative potential energy?

Yes, since the choice of the zero of potential energy is arbitrary

On a smooth horizontal floor, an object slides into a spring which is attached to another mass that is initially stationary. When the spring is most compressed, both objects are moving at the same speed. Ignoring friction, what is conserved during this interaction?

momentum and mechanical energy

A baseball is thrown vertically upward and feels no air resistance. As it is rising

its momentum is not conserved, but its mechanical energy is conserved

In a perfectly ELASTIC collision between two perfectly rigid objects

both the momentum and the kinetic energy of the system are conserved

In an INELASTIC collision between two objects

the momentum of the system is conserved but the kinetic energy of the system is not conserved

A shell explodes into two fragments, one fragment 25 times heavier than the other. If any gas from the explosion has negligible mass, then

the momentum change of the lighter fragment is exactly the same as the momentum change of the heavier fragment

Jacques and George meet in the middle of a lake while paddling in their canoes. They come to a complete stop and talk for a while. When they are ready to leave, Jacques pushes George's canoe with a force to separate the two canoes. What is correct to say about the final momentum and kinetic energy of the system if we can neglect any resistance due to the water?

the final momentum is in the direction opposite of F but the final kinetic energy is zero

A 1.0-kg block and a 2.0-kg block are pressed together on a horizontal frictionless surface with a compressed very light spring between them. They are not attached to the spring. After they are released and have both moved free of the spring

the lighter block will have more kinetic energy than the heavier block

## Collision:

A collision is an event in which two or more objects interact with each other for a short amount of time. The interaction can take place by contact or non-contact forces.

During a collision, the two objects exchange momentum and kinetic energy. The final momentum and kinetic energies of the object depends on their initial momentum, kinetic energy, and the nature of collision.
