The work done to stop a car during collision is described in the equation W = F * d where F is the force of collision and d is the distance of impact. In this case, when work is constant and the distance is long, then the force must decrease. If the distance shortens, then the force of collision must increase. The inflation deflation process of the airbag lengthens the distance, hence force is lessened.
Concave mirrors can make a real image.when the object is away from the mirror it is called real image and when the object is closer to the mirror it is called virtual mirror.
Elaborate rehearsal involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of long-term memory.
Six strategies of elaborate rehearsal are:
1. Rephrase information into your own words.
2. Create your own study questions and answer them.
3. Use images to help you.
4. Group terms that are of the same topic together.
5. Use a mnemonic strategy.
6. Space our your learning and don't try to cram in on sitting.
