Newton's Laws

What is the agreed upon position from which motion can be measured (ex. a tree, a building, a map or a coordinate plane). reference point
Describe Newton's 1st law. An object at rest will stay at rest and an object in motion will stay in motion at a constant speed in the same direction unless acted upon by an unbalanced force.
Describe Newton's 3rd law. For every action, there is an equal and opposite reaction.
What is the word for the amount of matter in an object? mass
What is the unit of measurement for mass? kilograms (kg)
What is motion? a change in position
Describe Newton's 2nd law. An object acted upon by an unbalanced outside force will accelerate in the direction of the force. The amount of acceleration depends upon the force applied and the mass of the object.
What is force? a push or a pull
What is acceleration? A change in the velocity of an object.
When does acceleration happen? When there is a change in the speed and/or direction of an object.
What is speed? How fast something is moving.
What is velocity? The speed AND direction of an object.
How do we calculate speed? speed=distance/time
