Velocity
The definition of Velocity
describes how fast an object moves and in what direction
acceleration is
The rate of change of velocity
The color of Smurfs
Blue
The 'force' that pulls masses towards each other
Gravity

If a car travels 120 km in 3 hours, this is its average velocity
40km/hr
A car speeds up from 10 m/s to 30 m/s in 5 seconds. This is its acceleration
4 m/s²
Tetris features falling theses from the sky
Blocks
The acceleration of A 10 kg object being pushed with a net force of 30 N.
3 m/s²

301
Velocity, but without the direction
Speed
This type of acceleration occurs when only gravity acts on an object
Free Fall
The Hardest Natural Substance on Earth
Diamond
An object is moving at a constant velocity. Describe the net force acting on it and explain what this implies about its acceleration.
Net force is 0, so there is no acceleration

The Extensions
A runner moves 50 m east in 10 seconds. Then 20 m west in 5 seconds. This is her total displacement.
30m east
A combination of an object's component velocities
Resultant Velocity

These are the monikers of Newton's 3 laws

An object moves in a circle at constant speed. This is why we say its velocity is changing.
its direction
An object has an acceleration of zero. Describe its motion.
moving at constant velocity.

Weight down, normal force up (normal force is greater than weight)
