# 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

A

Velocity

5
Q

Displacement-time graphs Curve

A

Acceleration (use tangent to find velocity)

6
Q

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```
