Reflection
The bouncing of light is called reflection.
Generally the one moving as The expectation is that the driver of a moving vehicle is in control of that vehicle and can safely stop before hitting a stationery object.
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
I'm pretty sure that's going to depend on the vehicle's mass. I'm sitting here performing a gedanken experiment right now, with a house fly and a Mercedes both hitting the same brick wall.
The bouncing force comes from the impact between an object and a surface, causing the object to lose momentum and rebound in the opposite direction. This bouncing force is a result of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Reflection
Waves bouncing off an object is called reflection.
The word is "reflection."
