Force and Motion
(Newton's 1st Law)
Vocabulary:
Force: a push or a pull
Mass: a measure of the amount of matter in an object
Motion: movement
Inertia: the tendency of an object to resist a change in its state of motion (at rest or in motion)
Friction: a force that opposes another object moving past another
Position: location
Constant: same, no changes (level)
Incline: increase (upward)
Decline: decrease (downward)
Speed: how fast an object's position is changing with time at any moment
Formula for Speed: speed = distance / time
Velocity: the speed of an object taken together with its direction (speed and direction)
Acceleration: a change in velocity (an increase, causes it to accelerate...gas pedal)
Deceleration: a change in velocity (a decrease, causes it to decelerate...brake pedal)
Gravity: a force that pulls things to Earth and helps keep Earth moving around the Sun
Newton's First Law of Motion-Inertia: an object at rest will stay at rest UNTIL a force acts
upon it, an object in motion will stay in motion UNTIL a force acts upon it
