Physics P456 practice exam questions

I am currently undergoing my gcse's and i wanted to create flashcards for myself but most importantly for the people who will be doing the same in the future x

HideShow resource information
What do arrows show?
• Arrows show the size and direction of force, a larger force = longer arrow
1 of 12
what is momentum?
• Momentum is how hard an object is to stop; heavier and faster objects have a larger momentum
2 of 12
give me 4 examples of car features: (physics wise)
Crumple zones crumple on impact increasing time to stop. Helmet padding increases the time for your head to stop. Air bags slow you down more gradually. Seat belts stretch and slow you down slowly.
3 of 12
what is kinetic energy?
Kinetic energy is movement. Anything moving has kinetic energy.
4 of 12
what is Gravitational Potential Energy (GPE) ?
GPE is height energy.
5 of 12
what is electric current?
Electric current is the flow of charge around a current.
6 of 12
what is a series circuit?
Series circuits are one continuous loop.
7 of 12
what is a parallel circuit?
Each component is separately connected to the + and – side of the battery. If you remove one, it’ll hardly affect the others.
8 of 12
what do waves have?
Waves have amplitude, wavelength and frequency.
9 of 12
what is frequency?
• Frequency is the number of waves passing past a certain point per second or the number of waves produced by a source each second.
10 of 12
what is diffraction
Waves spreading out
11 of 12
what is a wave interference?
when waves meet they cause an interference.
