PHY2048 Chapter 3: 1-D Kinematics/Motion in a Straight Line-
Questions with Correct Answers/ Verified
kinematics - ✔️✔️study of motion, distance & time, speed & velocity, accelerations. These are
vectors !
position - ✔️✔️the location of an object; in basic terms - where something is
displacement - ✔️✔️the change in position of an object
velocity - ✔️✔️change in position per unit of time (it is also the derivative of the change in
displacement)
acceleration - ✔️✔️change in velocity per unit of time (it is also the derivative of the change in
velocity)
speed - ✔️✔️This is a scalar value used to describe the distance traveled per unit of time.
average velocity - ✔️✔️the total displacement divided by the time interval during which the
displacement occurred
average speed - ✔️✔️total distance divided by total time
instantaneous velocity - ✔️✔️the velocity of an object at some instant or at a specific point in the
object's path
position equation for constant velocity - ✔️✔️final position = initial position + (velocity*time)
xf = xi + v(t)
or
x = x0 + v(t)
