Acceleration change of velocity over time (increasing, decreasing, or changing direction)
Constant acceleration a steady change in velocity (free falling near the surface of the Earth)
Speed-time graphs speed axis and time axis combine to show the acceleration via the slope
Negative acceleration when an object is slowing down over time
Positive acceleration when an object is speeding up or gaining speed
Unbalanced forces cause an object to move or accelerate
Balanced forces does not move and net force equals zero
Inertia property of matter that resists change
Newton’s 2nd Law of Motion acceleration of an object is equal to the net force acting on it divided by the object’s mass
Newton’s 3rd Law of Motion one object exerts force on a second object, the second object exerts an equal and opposite force on the first object (action/reaction forces)
Centripetal force force that keeps an object moving in a circle
Velocity v = d/t
Weight mass x acceleration due to gravity
