Vector for speed
Velocity (ms^-1)
What is instantaneous velocity
The velocity at a specific time.
How does a s/t graph look when there’s uniform velocity?
Straight line.
In an s/t graph (of uniform velocity), what do specific items represent?
-A coordinate represents v=u+at
-The gradient shows velocity
-Straight lines imply constant velocity.
How does a v/t graph look like when there’s uniform velocity?
-Horizontal line.
In a v/t graph (of uniform velocity), what do specific items represent?
-Area under graph shows the distance covered
-Gradient indicates acceleration.
-Straight slanted lines imply constant acceleration
How does an a/t graph look like when there’s uniform velocity?
-Dispersed L’s across the graph
In an a/t graph (of uniform velocity), what do specific characteristics represent?
-Horizontal lines imply constant acceleration
-The area under the graph indicates the change in velocity.
How does a s/t graph look like when there’s acceleration?
-Curve upwards
In an s/t graph (of acceleration) what do specific items represent?
-Tangent represents instant velocity
-Gradient
How does a v/t graph look like when there’s uniform acceleration?
Straight line.
In a v/t graph (of uniform acceleration), what do specific items represent?
-Area under graph is the change in position
-Gradient represents v=u+at
How does an a/t graph look like when there’s uniform acceleration?
Horizontal line
