Science: Physics

frame of reference a visible boundary in which motion occurs
reference point a stationary object used to determine if another object is moving
point of origin the place from which motion begins
distance the space traveled between two points
displacement the shortest distance between two points represented with a straight line (includes direction(vector))
force a push or pull
What unit is used to measure force? Newtons (N)
What type of forces result in a change in the speed and/or direction of motion? Unbalanced forces
What type of forces result in zero net force? Balanced Forces
Is gravity a push or pull? pull
What is the unbalanced force that brings nearly everything on Earth to a stop? friction
Newton's 1st Law An object in motion will stay in motion and an object at rest shall stay at rest, unless acted upon by an outside force.
Newton's 2nd Law As force increases, acceleration increases. As mass increases, acceleration decreases. F=ma
Newton's 3rd Law Every action has an equal and opposite reaction
inertia the tendency of an object to remain unchanged (property of matter)
In Newton's 2nd law, mass and acceleration have a(n)________ relationship indirect
In Newton's 2nd law, force and acceleration have a(n)________ relationship direct
