Physics: Chapter 3
107,00 kilometers per hour - correct answer ✔how we are moving relative to
the sun
Galileo - correct answer ✔credited with being the first to measure speed by
considering the distance covered and the time it takes
speed - correct answer ✔defined as the distance covered per unit of time,
how fast something moves
speed equation - correct answer ✔distance/time
slash symbol (/) - correct answer ✔is read as per and means divided by
instantaneous speed - correct answer ✔is the speed at any instant
average speed equation - correct answer ✔total distance covered/time
interval
total distance covered equation - correct answer ✔average speed x time
velocity - correct answer ✔how fast an object is going and in what direction,
we need to know both the speed and the direction of an object for this
vector quantity - correct answer ✔a quantity in physics that specifies a
direction and a magnitude is called this
