The Sign of Acceleration
![Page 10: Acceleration and non-uniform motion. P-T Graph Changing velocities means it is NON-uniform motion - this means the object is accelerating. m/s 2 m/s.](https://reader038.fdocuments.in/reader038/viewer/2022110101/56649ef05503460f94c00246/html5/thumbnails/10.jpg)
Velocity and Acceleration have SAME sign: object is SPEEDING UP
Velocity and Acceleration have OPPOSITE sign: object is SLOWING DOWN
![Page 11: Acceleration and non-uniform motion. P-T Graph Changing velocities means it is NON-uniform motion - this means the object is accelerating. m/s 2 m/s.](https://reader038.fdocuments.in/reader038/viewer/2022110101/56649ef05503460f94c00246/html5/thumbnails/11.jpg)
· Acceleration is calculated as the change in velocity over the change in time.
· Acceleration has units of distance/time/time such as m/s/s (m/s2)
· Acceleration is a vector quantity.

Uniform motion - average velocity is the same as instantaneous velocity on a P-T graph.
Instantaneous velocity is the velocity of an object at a specific instant in time.

To find velocity for a specific time, you must estimate by making a straight line at that point.
Slope of this line gives instantaneous velocity for that specific time on the curve.

A P-T graph with a changing slope means motion with changing velocity (non-uniform / acceleration)
v = + 2 m/s
v = + 5 m/s

Motion is described in words.
Motion is described with a (data) table of values.
Motion is described with a graph.
Motion is describe with equations.
The study of motion (Kinematics) involves: Position, Velocity, Acceleration
