2.2 Motion graphs Flashcards
1
Q
DTG - straight horizontal line
A
stationary
2
Q
DTG - sloping line
A
constant velocity
3
Q
DTG - curve line
A
acceleration / deceleration
4
Q
Acceleration
A
Object’s speed changes over time
5
Q
constant acceleration on DTG
A
- smooth and regular curve
- speed of object is increasing at a
steady rate
6
Q
DTG - gradient
A
velocity
7
Q
DTG - how do you determine instantaneous velocity (acceleration)
A
- draw tangent
- calculate gradient of this tangent

9
Q
Displacement time graphs
A
shows how far an object moved from it’s starting point and the time it took to move that distance.
10
Q
Velocity time graphs
A
shows how quick an object is travelling against time
