Motion Flashcards
What is speed?
Distance travelled each second.
What is the equation for speed?
Speed (m/s) = distance (m) / time (s)
What happens to the velocity if the direction changes?
The velocity changes.
If the direction changes, what happens to the speed?
It can stay the same.
What is velocity?
Speed in a given direction.
How does braking affect velocity?
Braking reduces velocity.
What is acceleration?
Change of velocity per second.
What is deceleration?
Change of velocity per second when an object slows down.
On a distance-time graph, what does the gradient tell you?
The speed.
On a distance-time graph, what does a steeper slope tell you?
The speed is greater.
On a distance-time graph, what does a straight line tell you?
The object is stationary.
What is the equation for acceleration?
Acceleration = change in velocity / time taken
On a velocity-time graph, what does the gradient tell you?
Acceleration.
On a velocity-time graph, what does the area tell you?
Distance travelled in a given time.
