What is the 1st law of motion
An object in motion or at rest, will stay at rest or in motion unless acted upon by an unbalanced force
What is Velocity
Distance/Time with a direction
through scientific investigation
You kick a bowling vs a soccer ball the soccer ball goes faster which law of motion is that
Law 2

Fnorm Fgrav Ffric
What is the 2nd law of motion
F=MA
What is Acceleration
A mean of how much velocity changes over time
What is the Law of falling bodies
2 objects with the different masses will fall at the same speed as each other
F=MA can be convertered into what other formula
W=MG
What is a balnaced force
A pair of forces that are equal and opposite
What is the 3rd law of motion
Every action has an equal and opposite reaction
