Chapter 1 - Motion Flashcards
1
Q
How does the line of a distance-time graph look like if the object is stationary
A
It’s horizontal
2
Q
What does velocity mean
A
The speed in a given direction
3
Q
What does the gradient of the line on a distance-time graph represent
A
Speed. The steeper the gradient, the faster the speed
4
Q
What is acceleration
A
The change of velocity
5
Q
What is the equation for acceleration
A
A= v - u
\_\_\_\_\_
t
A= Acceleration (m/s2)
V= Final velocity (m/s)
U= Initial velocity m/s)
T= Time take for the change (s)
6
Q
What does the gradient of the line on a velocity-time graph represent
A
Acceleration. The steeper the gradient the greater the acceleration
7
Q
What does it mean if the line on a velocity-time graph is horizontal
A
The acceleration is zero, so it is travelling at a steady speed
8
Q
What does it mean if the gradient of a velocity-time graph is negative
A
The object is decelerating
