P9 - Motion Flashcards
1
Q
What is speed?
A
How fast something moves.
Formula: Speed = distance / time
2
Q
What is velocity?
A
Speed with a direction (e.g., 20 m/s north)
3
Q
What is acceleration?
A
How quickly velocity changes.
Formula: Acceleration = (change in velocity) / time.
4
Q
What do distance-time graphs show?
A
They show how far something moves over time.
Straight line = constant speed
Steeper liner = faster speed
5
Q
What do velocity-time graphs show?
A
They show how velocity changes over time.
Steeper line = faster acceleration
Flat line = constant velocity
6
Q
How can you find acceleration on a velocity-time graph?
A
Find the slope ( gradient of the graph.
