    Modern Technology in a Historical Setting: Impact on Society

    If you went back in time and brought with you modern day devices, could you teach the people of that day (to a certain extent) how to create and use these devices? What impact would this have the modern day? Would we be more evolved?

    Speed, force, velocity, (falling object)

    Here i will state the question directly: Assume the egg is not encased in an egg holder:(Note the time taken by the egg to hit the ground is 0.1s and the hight of the balcony is 4m.) a). calculate the speed with which the egg, when dropped from the first floor balcony will hit the ground.(Use...

    Speed, force, velocity, (falling object)

    Everyone knows that an egg would not really take 0.1 seconds to fall four meters. This question has been just simply used to test my knowledge about Newtons laws, force, velocity.(which isn't very much).

    Speed, force, velocity, (falling object)

    thanks for the tips but i haven't learned anything about that so far on kinematics equations ect.

    Speed, force, velocity, (falling object)

    Thank you but I believe I needed to use Newtons laws for the first question and I'm not sure that I did.

    How does recovery of braking energy improve I.C. engine performance?

    Don't Formula One cars use this?... I don't know the physics behind it.

    Speed, force, velocity, (falling object)

    Homework Statement (A) An egg (57g) is dropped from a balcony 4m high,calculate the speed with which the egg, when dropped from the first floor balcony will hit the ground. ( use Newtons laws). ( note the time taken for the egg to hit the ground is 0.1s) (B) What force from the ground will be...

    Impact Force (helmets) Safety Devices

    I'm doing a physics assignment on safety devices such as helmets and i need help with a question. Why is the Impact force reduced for a helmet with a soft interior VS a hard interior? I know it is because the soft padding on the inside of soft the helmet will reduce the time taken for your...

    Some Questions on Physics (Force) HELMETS

    1. Why is the force reduced for a helmet with a soft interior VS Hard interior? 2. What points would need to be considered during design and construction to ensure that the impact on the body is decreased? What criteria must be met? 3. Why should a helmet be replaced every 5 years...
