2.1 speed, distance & time Flashcards
1
Q
Speed
A
The rate at which an object covers distance, without considering it’s direction
2
Q
Displacement
A
The overall change in position of an object in a specific direction
3
Q
Velocity
A
Speed with direction, or how quickly displacement changes over time.
4
Q
Acceleration
A
How quickly velocity changes over time, indication a speed increase or decrease in a particular direction.
5
Q
what quantities are velocity and acceleration and why?
A
- vector quantities
- because they have both
magnitude and direction
6
Q
Average speed
A
Total distance traveled /
total time it took
7
Q
Instantaneous speed
A
Speed of an object at any specific moment.
8
Q
What does s represent
A
displacement / m
9
Q
what does u represent
A
initial velocity / m s-1
10
Q
what does v represent
A
final velocity / m s-1
11
Q
what does a represent
A
acceleration / m s-2
12
Q
what does t represent
A
time / s
