Average velocity
A vector quantity with both, a magnitude and direction.
Vector quantity
A quanitity with both, magnitude and direction.
x m
If displacement (________ /s) is plotted against time (t s), a line with a slope /gradient will be obtained which tells the magnitude of the average velocity.
one dimensional motion
In the case where an object moves along a single axis, it is called ________.
curve of v
Graphically, the acceleration at any point is the slope of the ________ (t) at that point.
Free-fall acceleration
The rate at which an object would fall if all the effects of air on it could be ignored.
straight line
The motion is along a(n) ________ only which may be vertical, horizontal or slanted but must be straight.
Displacement
A vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.
Acceleration
The rate of change of the velocity of an object with respect to time.
Average velocity
The ratio of the change in displacement that occurs during a particular time interval.
One purpose of physics is to study the motion of objects which can be divided into two main categories
how fast an object moves, and how far an object travels in a given time
Average velocity is the ratio of the change in displacement that occurs during a particular time interval, i.e, final
initial velocity/ time taken
This slope connects two points on the graph
one that corresponds to x1 and t1, and another that corresponds x2 and t2
Kinematics
the branch of mechanics concerned with motion without reference to force or mass.
