what are newtons three laws
law of inertia
acceleration
reaction
define displacement
is the change in postion a vector quantity
define average speed
total distance travalled divided by the time it took to get there
definr instantaneous speed
is the speed that an object is travelling at in a particular moment
define constant speed
constant speed or uniform motion is the speed of an object remaining the same over a portion of timr
definr acceleration
is the rate of change in speed. scalar. gravity is 9.8m/s 2
define average acceleration
is the average rate of change in speed
define postion
is the seperation and direction from a reference point
define scalar quantity
quantities described only with a magnitude
define vector
quantities described with both magnitude and direction
