IB DP Physics: HL復習筆記2.1.3 Acceleration
Acceleration Acceleration?is defined as the?rate of change of velocity In other words, it describes how much an object's velocity?changes?every?second The equation below is used to calculate the av...
IB DP Physics: HL復習筆記2.1.2 Speed & Velocity
Speed & Velocity Speed The?speed?of an object is the distance it travels every second Speed is a?scalar?quantity This is because it only contains a magnitude (without a direction) The?average s...
IB DP Physics: HL復習筆記2.1.1 Distance & Displacement
Distance & Displacement Distance?is a measure of how far an object travels It is a?scalar quantity - in other words, the direction is not important The athletes run a total distance of 300 m Co...
