What is the Difference between Speed and Acceleration?
(Extra 100 points each if you can say the Units that we measure both)
Speed is how fast something is moving (m\s or km\h)
Acceleration is the change in speed over time (m\s2 or km\h2)

What is Newton's Law of Inertia
An object will continue to be at rest (not move)
OR
keep moving in a straight line (no change in motion)
unless acted on by an external force.
