Linear Motion, Projectiles and Collisions Flashcards
1
Q
Symbols in linear motion
A
S displacement
U initial velocity
V final velocity
A acceleration
T time
2
Q
Equations of Linear motion
A
v=u+at
S= ut + ½at^2
s= ½ (u+ v)t
v^2 = u^2 + 2as
S = vt - ½at^2
3
Q
Acceleration in a velocity-time graph
is found
A
By finding the gradient
4
Q
The area under a velocity-time graph is…
A
The displacement
5
Q
What is velocity
A
The rate of change of displacement
v=Δs/Δt
6
Q
What is acceleration?
A
The rate of change of velocity
a=v-u/Δt
ms-2
7
Q
What is displacement?
A
The distance moved in a particular direction from a fixed point
8
Q
The slope or gradient of a displacement-time graph gives
A
The velocity
9
Q
What is speed and its formula
A
The rate of change of distance
v=s/t
10
Q
What is linear motion?
A
Motion in a straight line
11
Q
Average speed formula
A
u+v/2
