P2- Motion Flashcards
What are the axis on a distance-time graph?
Distance➡️Y-axis.
Time taken➡️X-axis.
What is the equation to calculate speed?
Speed (m/s)= Distance (m)/ Time taken (s).
Define velocity.
Velocity is speed in a given direction.
Define acceleration.
Acceleration is the change of velocity per second.
What is the equation to calculate acceleration?
a (m/s2)= (v-u)/t
What is the unit for speed and velocity?
m/s
Metres per second.
What is the unit for acceleration?
Metres per second squared.
If the line on a velocity-time graph is horizontal, what does this mean?
The acceleration is zero.
The area under the line on a velocity-time graph tells us….
Distance travelled.
The gradient of the line on a velocity-time graph gives…
The acceleration of an object.
Define speed.
Distance travelled each second by an object.
