- 1: newtons law __- inertia, an object at rest will stay at rest and an object in motion will stay in motion unless acted on by an unbalanced force
- 2: newtons law __ force=mass x acceleration
- 3: newtons law __for every action there is an equal and opposite reaction
- 9.8: near the earths surface, gravitational acceleration is ___m/s/s

- force=: mass x acceleration
- forces: a paper on a desk has balanced _____ acting on it
- frame of reference: object or point from which motion is determined
- friction: force that opposes motion
- gravity: force of attraction between all objects in the universe
- hypothesis: prediction based on patterns and observations
- inertia: an objects tendency to resist a change in motion
- meter: length unit

- parabola: distance time graph for acceleration is always a curved line, or ____
- projectile: any object that is thrown
- speed: distance traveled per unit of time

- unbalanced: _____ forces are not equal
- unbalanced: for every force, there is an ______ force
- velocity: speed in a given direction
- volume: amount of space an object takes up
- weight: measure of the pull of gravity on an object
