When you use a plane mirror, like a normal one in your house, it does not enlarge or reduce the size of the image. How does the distance of the image compare to the distance of the object?
object distance is same as image distance
image seems farther away than object
image seems closer than object

When playing billiards (pool) and you hit the cue ball into another ball. What happens if you hit the cue ball directly into another ball?
cue ball stops- other ball moves at cue ball speed
cue ball and other ball move at original speed
cue ball move backwards at same speed of other ball
cue ball and other ball stop immediately

slower car has more friction
slower car has more inertia
