1

Distance is...

the space between two fixed positions.

2

Displacement is...

the distance between two fixed points and the direction from one and other.

3

Speed is...

the rate of change of distance.

4

Velocity is...

the rate of change of displacement.

5

Acceleration is...

the rate of change of velocity.

6

Displacement-time graph:

-the gradient is the velocity

7

Instantaneous speed is speed...

at a certain point.

8

Velocity-time graph:

-gradient is acceleration
-area is displacement

9

V=

u + at

10

s=ut +

0.5 x at squared

11

s=

0.5 x (u+v) x t

12

v2 =

u2 + 2as

13

Trajectory is...

the path of any moving object.

14

A projectile is an object...

that is given an initial force then allowed to move freely through space.

15

A parabola is a name...

given to the shape of the curve, a projectile follows when gravity is the only force acting on it.
