3
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.
New cards
4
one dimensional motion
In the case where an object moves along a single axis, it is called ________.
New cards
5
curve of v
Graphically, the acceleration at any point is the slope of the ________ (t) at that point.
New cards
6
Free-fall acceleration
The rate at which an object would fall if all the effects of air on it could be ignored.
New cards
7
straight line
The motion is along a(n) ________ only which may be vertical, horizontal or slanted but must be straight.
New cards
8
Displacement
A vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.
New cards
9
Acceleration
The rate of change of the velocity of an object with respect to time.
New cards
10
Average velocity
The ratio of the change in displacement that occurs during a particular time interval.
New cards
11
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
New cards
12
Average velocity is the ratio of the change in displacement that occurs during a particular time interval, i.e, final
initial velocity/ time taken
New cards
13
This slope connects two points on the graph
one that corresponds to x1 and t1, and another that corresponds x2 and t2
