Describing Motion Flashcards
1
Q
Velocity
A
Rate of change of displacement
2
Q
Speed
A
Rate of change of distance
3
Q
Acceleration
A
Rate of change of velocity
4
Q
Displacement-time graphs Gradient
A
Velocity
5
Q
Displacement-time graphs Curve
A
Acceleration (use tangent to find velocity)
6
Q
Velocity-time graphs Gradient
A
Acceleration
7
Q
Velocity-time graph straight line
A
constant velocity
8
Q
Velocity-time graph area
A
Displacement
9
Q
Projectiles (time to hit ground)
A
Use suvat
10
Q
Projectiles (Distance from place it fell)
A
use distance = speed x time
speed = in question Time = SUVAT (normally in previous question)
11
Q
Projectiles at angles (how long in air)
A
Use suvat (vertical component as u) double answer because projectiles at an angle are parabolic
12
Q
Projectiles at angles (Maximum height)
A
Use suvat with vertical component as u to work out t
13
Q
Projectiles at angles (How far away does it land)
A
Use distance = speed x time
speed = horizontal component time = suvat with vertical component as u to work out t
