1.2 Kinematics Flashcards
1
Q
What are the equations of motion?
A
v = u + at
x = ½(u+v)t
x = ut + ½at²
v² = u² + 2ax
2
Q
What is the mean speed/ velocity ?
A
total distance/displacement travelled/ total time taken Δv/ Δt
3
Q
What is the instantaneous speed/ velocity?
A
Rate of change of distance/ displacement of the speed/ velocity in an instant
4
Q
What is the displacement?
A
The displacement of two points is the shortest distance between them together with direction
5
Q
What is the terminal velocity?
A
The maximum velocity of an object when the resistive forces on it are equal and opposite to the ‘accelerating’ force.
