Motion Flashcards
(8 cards)
1
Q
What is motion?
A
A change in position of an object with respect to time.
2
Q
What is speed?
A
Distance travelled per unit time. It is a scalar quantity.
3
Q
What is velocity?
A
Displacement per unit time. It is a vector quantity.
4
Q
What is acceleration?
A
The rate of change of velocity.
5
Q
What does uniform motion mean?
A
Motion at constant speed in a straight line.
6
Q
What does non-uniform motion mean?
A
Motion with changing speed and/or direction.
6
Q
What is the difference between distance and displacement?
A
Distance is the total path length (scalar); displacement is the shortest path from start to end (vector).
6
Q
Can an object have constant speed but changing velocity?
A
Yes, if it is changing direction (e.g., moving in a circle)
