1.2 Velocity and Acceleration Flashcards
1
Q
Why would an objects velocity change even though it’s speed stays the same?
A
It changed direction
2
Q
What do we call it when an objects velocity changes?
A
Acceleration
3
Q
How can we calculate the acceleration of an object?
A
(Final velocity in m/s - start velocity in m/s) / time taken for the change in s = acceleration in m/s2
4
Q
What is deceleration?
A
If an object is slowing down and the acceleration is negative
5
Q
What is velocity?
A
Speed in a given direction
6
Q
What is the unit for acceleration?
A
Metres per second squared
M/s2
