Name 4 things that effect the thinking distanc |
Alcohol, Drugs, Distractions, Age |
Effects in the body system |
|
|
What happens when a moving trolley hits a static trolley? |
The moving trolley hits the static trolley and all of the energy is passed onto the static trolley to make it move at the same speed as the moving trolley. This is called The Law Conservation of Momentum |
|
|
|
What happens when you apply brakes on a car? |
Kinetic energy while moving, heat energy while the brakes are applied |
What energy is transferred? |
|
|
What is terminal velocity? |
The speed you are travelling at a given direction |
|
|
|
When the parachutist deploys his parachute does the air resitance increase or decrease |
Increased dramatically |
|
|
|
What is power measured in? |
Watts (W) |
|
|
|
What is energy measured in? |
Joules (J) |
|
|
|
Finish off this sentence: When a force is applied to an object the velocity changes, so the momentum '?' |
Changes |
|
|
|
What are KERS? |
Kinetic Energy Recovery System amd the reserve heat energy into kinetic energy, it uses electrical generator insted of brakes to slow the car down and uses that energy to boost the cars battery when needed |
|
|
|
What do shiny surfaces do and matte surfaces? |
Shiny surface reflect Infrared Radiation whereas , matte surfaces absorb IR hence why white reflects some heat and absorb whereas all black surface absorb. The darker the colour more IR is emitted |
|
|
|
What is the common phrase in Specific Heat Capacity? |
The greater the mass the higher its temperature and therefore stores the most energy |
|
|
|
Finish off this sentence: The higher the effiencency the more of the input energy is transferred into usefull forms of '?' |
Energy |
|
|
|
In the EM spectrum what waves do a) Gamma Rays b) Radio Waves |
a) Short wavelength, high frequency b) Long wavelength, low frequency |
|
|
|
Tue or False the angle of incidence is different to the angle of reflection? |
False as the incident angle and the reflected angle are equal |
|
|
|
Fill in the missing word(s): Ray reflected towards the normal, when it is less dense. No refraction takes place at a 90 degree angle. The light '?' down when it goes from more dense to less dense but when the light rays go from less dense to '?' dense it speeds up |
1) slows 2) more |
