Describing Motion
What is the rate of change of an object's position over time called?
Velocity
An object starts from rest and accelerates at a rate of 4 m/s2 for 2 seconds. What is its final velocity?
8 m/s
What is Newton's First Law of Motion?
An object in motion tends to stay in motion unless acted upon by an outside force.
A weight of 20 N hangs from a rope. What is the tension in the rope?
The Grand Army of the Republic was made of up clones created from the DNA of this bounty hunter.
Jango Fett
Velocity has a direction; speed does not. This means that velocity is a ___________ quantity.
Vector
An object's initial velocity is 5 m/s. It accelerates at 4 m/s2 for 2 seconds. What is the object's final velocity?
13 m/s
What is Newton's Second Law of Motion?
F = ma
If the mass of an object doubles, but the force applied to it stays the same, the acceleration of the object will...

Acceleration
An object accelerates from rest to 30 m/s in 6 seconds. What is its acceleration?
5 m/s2
What is Newton's Third Law of Motion?
For every action, there is an equal and opposite reaction.

Ilum
A car is moving at a constant 20 m/s. After 10 seconds, how far will it have travelled?
200 m
A car’s initial velocity is 20 m/s. The driver hits the brakes, causing an acceleration of -4 m/s2. How far does the car travel before it comes to a stop?
50 m
