physics Flashcards
what 2 properties may affect the resultant force
- speed
- direction
what do we call it when all the forces acting on an object balance out
equilibrium
what is it called when an object returns to it’s original state after all forces have been removed
elastic deformation
what is it called when an object does not return to it’s original state after all the forces have been removed
inelastic deformation
what does a higher springs constant mean
it means that it requires more energy to stretch it (more stiff)
hooke’s law formula
F = k x e
when a wave has it’s oscillations perpendicular to the direction of energy transfer, what wave is this ?
transverse wave
when a wave has it’s oscillations parallel to the direction of energy transfer, what wave is this ?
longitudinal wave
in reflection the angle of incidence is always _______________ the angle of reflection
equal to
