Motion Flashcards
1
Q
Motion
A
Objects position changes with respect to time & observer
2
Q
Rest (stationery)
A
when objects position doesn’t change with respect to time
3
Q
Rest & Motion conditions
A
Object can’t be completely rest/motion
Position change due to time & observer
Object can be both rest & motion in given time
4
Q
Physical quantities
A
Quantities which are either vector/scaler obeying basic physics laws
5
Q
Scaler quantity
A
Only has magnitude (numerical value) no direction, only positive
Mass, distance, speed, area, volume, density, pressure, temperature
6
Q
Vector quantity
A
Has magnitude and direction can be positive, negative & 0
Displacement, velocity, acceleration, force, movement, weight, drag, thrust
