vector - ANSWERSa quantity that has both size and direction
acceleration - ANSWERSthe rate at which velocity changes with time; any change in velocity, faster OR
slower
velocity - ANSWERSthe speed in a specific direction
meter - ANSWERSthe standard unit of length
if velocity does not change - ANSWERSthen there is no acceleration
like velocity, acceleration - ANSWERSis a vector, which means it has both size and direction
when the acceleration is in the same direction as the object is moving - ANSWERSthe speed of an object
increases
when the acceleration is in the opposite direction as the object was moving - ANSWERSthe speed of the
object decreases
when the acceleration is at a right angle to the motion - ANSWERSthe direction of the object changes
but the speed does not change
to measure acceleration - ANSWERSyou need to know how velocity changes with time
a change in velocity - ANSWERScan be found by comparing the initial velocity and the final velocity of the
moving object
