    Why Does Steepness in a Potential Energy Graph Indicate Greater Force?

    A plot of a graph describes the potential energy of a particle, due to the force exerted on it by another particle, as a function of distance. At which three regions (Q), (W), (T) would the magnitude of force on the particle be the greatest? and why? [T]...

    Law of conservation of energy and momentum

    Two Objects collide head on, both with speeds of 10 m/s. Both projects emerge from the collision traveling in the same direction, each having at a speed 10m/s. How does this violate the conservation of momentum? The answer is: That it only violates the conservation of momentum. Why? I...
