Physics revision Flashcards
1
Q
Distance
A
Speed x Time
2
Q
Weight
A
Mass x gravitational field strength
3
Q
Definition of : Speed
A
How much distance is covered in how much time
4
Q
Average speed (Definition)
A
The overall distance travelled divided by the overall time for a journey
5
Q
Relative motion (Definition)
A
Different observers judge speed differently if they are in motion too, so an object’s speed is relative to the observer’s speed
6
Q
Acceleration (Definition)
A
Change in speed or direction eg if an object is moving in a circle at constant speed, it is accelerating
7
Q
Time
A
Speed divided by distance
