vocabulary p.1
An objects change in position relative to a reference point
What is motion?
The rate at which velocity changes
What is acceleration?
The constant speed of a free falling object
What is terminal velocity?
Units for distance and displacement
What is meter or kilometer?
An object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity, unless acted on by an unbalanced force
What is Newton's 1st Law Of Motion
An object (that's stationary) used to specifying a precise location of objects
What is frame or refence?
Any action that can change the state of motion of an object
What is force?
What is projectile motion?
What is the formula for speed?
What is s=d/t (speed=distance/time)
Force equals mass times acceleration
What is Newton's 2nd Law Of Motion?
Distance and direction of an objects change in position from the starting point
What is displacement?
Force that opposes motion between two surfaces that are in contact
What is friction?
A quantity defined as the product of mass and velocity of an object
What is momentum?
Units for acceleration are
What is km/hr/s or m/s/s
For every action there is an equal and opposite reaction
What is Newton's 3rd Law Of Motion?
Describes how fast an object moves
What is speed?
Resistance to accelerate when a object force is applied
What is mass?
The unit or measure of force
